Using Arduino General Electronics HassanAli23 October 23, 2020, 5:26pm 1 Hi everyone. I want to use an ESP8266 WIFI Module but I discovered that there are two different types which are the CP2102 and the CH340. I just want to know what the differences are between both of them. Thanks.1 Like alesam October 23, 2020, 7:18pm 2 Both of them Serial-USB converters just by different manufacturers. An CP2102 considered as a better one but from my experience there is no difference. Some people complained about problem with CH340 driver installation. However mostly it's just an old OS issue.1 Like groundFungus October 23, 2020, 8:42pm 3 I see no difference, either.

Certainly not a problem if you are using Linux (such as Mint).

Did you read the data sheets? All the answers you would ever need are there. 6v6gt October 25, 2020, 9:09am 6

In general, that is of course true. However, information like difficulties of obtaining/installing compatible drivers is something that community experience can better provide. If you are choosing an ESP8266 development board, the one I favour is the Wemos D1 mini. It is compact and breaks out all the usable pins. There are some clones, however, that have strange feature like, for example, a non standards voltage divider resistor pair on the analog pin. Other, larger breakouts, often duplicate many pins and are difficult to use on a breadboard, but could also have a stronger voltage regulator.4 Likes sblantipodi January 12, 2021, 8:45am 7 In my experience *CP2102 caps at 500K baud rate, * *CH340 can go easily up to 1 million baud rate. *IMHO CH340 is the best alternatives2 Likes system Closed May 12, 2021, 8:46am 8 This topic was automatically closed 120 days after the last reply.
