Created by Espressif Systems, ESP32 is a low-cost, low-power system on a chip (SoC) series with Wi-Fi & dual-mode Bluetooth capabilities! The ESP32 family includes the chips ESP32-D0WDQ6 (and ESP32-D0WD), ESP32-D2WD, ESP32-S0WD, and the system in package (SiP) ESP32-PICO-D4. At its heart, there's a dual-core or single-core Tensilica Xtensa LX6 microprocessor with a clock rate of up to 240 MHz. ESP32 is highly integrated with built-in antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules. Engineered for mobile devices, wearable electronics, and IoT applications, ESP32 achieves ultra-low power consumption through power saving features including fine resolution clock gating, multiple power modes, and dynamic power scaling.

  • Processors:
    • Main processor: Tensilica Xtensa 32-bit LX6 microprocessor
      • Cores: 2 or 1 (depending on variation) All chips in the ESP32 series are dual-core except for ESP32-S0WD, which is single-core.
      • Clock frequency: up to 240 MHz
      • Performance: up to 600 DMIPS
    • Ultra low power co-processor: allows you to do ADC conversions, computation, and level thresholds while in deep sleep.
  • Wireless connectivity:
    • Wi-Fi: 802.11 b/g/n/e/i (802.11n @ 2.4 GHz up to 150 Mbit/s)

      • RTC fast SRAM: 8 KiB For data storage and main CPU during RTC Boot from the deep-sleep mode.
      • RTC slow SRAM: 8 KiB For co-processor accessing during deep-sleep mode.
      • eFuse: 1 Kibit Of which 256 bits are used for the system (MAC address and chip configuration) and the remaining 768 bits are reserved for customer applications, including Flash-Encryption and Chip-ID.
      • Embedded flash: Flash connected internally via IO16, IO17, SD_CMD, SD_CLK, SD_DATA_0 and SD_DATA_1 on ESP32-D2WD and ESP32-PICO-D4.
        • 0 MiB (ESP32-D0WDQ6, ESP32-D0WD, and ESP32-S0WD chips)
        • 2 MiB (ESP32-D2WD chip)
        • 4 MiB (ESP32-PICO-D4 SiP module)
    • External flash & SRAM: ESP32 supports up to four 16 MiB external QSPI flashes and SRAMs with hardware encryption based on AES to protect developers' programs and data. ESP32 can access the external QSPI flash and SRAM through high-speed caches.
      • Up to 16 MiB of external flash are memory-mapped onto the CPU code space, supporting 8-bit, 16-bit and 32-bit access. Code execution is supported.
      • Up to 8 MiB of external flash/SRAM memory are mapped onto the CPU data space, supporting 8-bit, 16-bit and 32-bit access. Data-read is supported on the flash and SRAM. Data-write is supported on the SRAM.
      ESP32 chips with embedded flash do not support the address mapping between external flash and peripherals.
  • Peripheral input/output: Rich peripheral interface with DMA that includes capacitive touch, ADCs (analog-to-digital converter), DACs (digital-to-analog converter), I²C (Inter-Integrated Circuit), UART (universal asynchronous receiver/transmitter), CAN 2.0 (Controller Area Network), SPI (Serial Peripheral Interface), I²S (Integrated Inter-IC Sound), RMII (Reduced Media-Independent Interface), PWM (pulse width modulation), and more.
  • Security:
    • IEEE 802.11 standard security features all supported, including WFA, WPA/WPA2 and WAPI
    • Secure boot
    • Flash encryption
    • 1024-bit OTP, up to 768-bit for customers
    • Cryptographic hardware acceleration: AES, SHA-2, RSA, elliptic curve cryptography (ECC), random number generator (RNG)
Clarification note: In this context, "RTC" is a bit of an "Espressifism" because it's used as shorthand for the low-power and analog subsystem which is separate from the CPU and the main "digital" peripherals ("digital" is another Espressifism). There is some real time clock functionality as part of the RTC subsystem, but there's also a lot of other stuff.

Community & Discussion

For most questions, it's probably best to submit a post in the forums for widest community visibility and easily writing out the nitty-gritty details of your situational context — for example, including example code and detailing the relevant configuration of your software, firmware, and hardware. Alternatively, real-time chat via IRC is a great way to converse with others, learn new things, and sometimes get answers to questions on the spot. But, having said that, the main drawback to online chat is that not everyone is active or looking at the channel (chat room) at the same moment — people work at different hours and live in different parts of the world — so timing can be hit-or-miss. So, if you ask a question in the IRC channel, try to stick around, as it might take someone awhile to respond.

  • Forum: ESP32.com (Official Espressif ESP32 Forums)
  • Chat: #ESP32 on IRC.freenode.net In order to connect to the #ESP32 chat channel on the Freenode IRC network, you will need to use an IRC client program. For long term usage, it's recommended to download a full fledged IRC client. However, for temporary usage, you can Freenode's webchat client.

  • Espressif: ESP32-ZERO V2 (surface-mount PCB module), ESP32-PICO Core Board V2, ESP32-PICO-KIT (ESP32-PICO Core Board) V3 & V4
  • Microwavemont: ESP32-PICO Motherboard, ESP32-PICO-ADB, ESP32-PICO Double Decker, ESP32-PICO-CAM, ESP32-PICO-tinyCAM

Compact Surface-Mount PCB Modules

The ESP32-based Wi-Fi/Bluetooth communication modules in the table below are surface-mount devices (SMD). Each module is a small printed circuit board upon which chips and other components are soldered and treated as an inseparable assembly to be integrated onto another PCB. All the modules listed below contain an ESP32 chip, a 40 MHz crystal (clock), and a flash memory chip, but vary in features such as antenna configuration, capacity of the flash memory chip, and EM shielding. Because these wireless communication module boards are designed for incorporation into final products (unlike development boards), they lack development components which are unnecessary or undesirable in final products — e.g., typically no USB-to-UART nor programming/reset buttons — minimizing both cost and physical size.

Note that the pSRAM column refers to inclusion of additional on-board pseudostatic RAM; this figure does not include the SRAM within the ESP32 chip itself.

Small & Medium Development Boards/Modules (Using PCB Module)

Development boards are designed to be easily worked with for the purpose prototyping and development. Typically this means connections are broken out with 0.1″ spaced headers (in contrast to the more tightly spaced connections seen on the compact surface-mount module boards). Furthermore, development boards often contain on-board components to aid in easy prototyping & programming — e.g., power-supply/regulation, USB-to-UART, and buttons for flashing & resetting.

Purchasing

Disclaimer: Vendors are listed here for informational purposes only. Buyers should use prudence and careful judgement when ordering. Before ordering, read all product descriptions and check vendor ratings when possible. Prices listed below are approximate and do not include shipping costs. Furthermore, prices listed below may be outdated, so be diligent and check for yourself.

Note to the beginner: If you are just getting started and don't know what to purchase, it would probably be best for you to purchase a development board (instead of an surface-mount module) for easier hardware setup and an better first time experience. Espressif's official, publicly sold development boards are ESP32-PICO-KIT, ESP32-DevKitC, and ESP-WROVER-KIT.

Note about Taobao: Taobao is a Chinese marketplace. For international shopping, intermediary agents are often used (for a fee, of course). Those unfamiliar with Taobao should read Naomi Wu's "Source Parts on Taobao: an Insider's Guide" and Eric's "How to Buy Directly from Taobao" before attempting to make a purchase through the venue.

QFN Packaged Chips

A few words of clarification because some people have erroneously confused chips with surface-mount PCB modules: If you wish to purchase just the Espressif ESP32 chip itself, understand that this means you're only receiving the fabricated silicon contained within a tiny Quad-Flat No-leads package. For those seeking integration/inclusion of ESP32, using an surface-mount module board with ESP32 inside is often more desirable, since such modules combine an ESP32 chip, 40 MHz crystal (clock), flash memory chip, and appropriate "glue" components into a ready-to-use, compact assembly. Having said that, if you wish to purchase only the chip and not a module board, you can purchase the chip through vendors listed below. You can also find sellers in venues like eBay and AliExpress using search queries with "ESP32" and "QFN", "SMT", "SMD", "package", "bare" or "raw"; also using the full identifier (such as "ESP32-D0WDQ6" or "ESP32-D2WD") in search queries may prove fruitful.

In addition to the sellers listed below, you can contact Espressif directly for chip purchase inquiries. For small quantities, Espressif will likely direct you to an appropriate distributor to contact. If you are a distributor or otherwise interested in ordering a large quantity of parts, the minimum order quantities for parts direct from Espressif are listed in the Espressif Products Ordering Information document.

  • SPI0 is permanently reserved for cache access to the flash chip. SPI1 is connected to the same pins via an arbiter and is used to write to flash. You can use SPI1 to also write to other peripherals connected in parallel with the flash (but with another /CS), however, this is tricky to implement because it means you can't simultaneously access flash anymore. Thats why it's not in the driver yet.
  • International System of Quantities (ISQ) notation is used to represent the measure of data described on this page. Notably, International Electrotechnical Commission (IEC) defined binary prefixes (based on powers of two) are used where appropriate; International System of Units (SI) defined metric prefixes (based on powers of ten) are used where appropriate. For the most part, this means you'll see binary prefixes — e.g., kibi (Ki) and mebi (Mi) — used for memory capacities and data sizes. However, low-level information transfer rates and networking data rates (notably Wi-Fi and Bluetooth data rates) typically focus on raw bits per second (without the notion of the byte) with multiples expressed in powers of ten; thus use metric prefixes. See Binary prefix, Orders of magnitude (data), Orders of magnitude (bit rate), and Data rate units on Wikipedia for more information.
