Converts USB to serial and includes essential programming circuits
Eliminates the need for separate programming circuits on the ESP32 board
Features dual port for Arduino and ESP8266/ESP32 programming
Equipped with a 3.3V/5V power switch, suitable for Arduino/ESP programming
The Makerfabs ESP32 Programmer USB2UART CH340K is a meticulously designed module that caters to the programming needs of ESP8266 and ESP32. It is based on the CH340K chip and serves a dual purpose. Not only does it convert USB to serial, but it also incorporates the essential circuits required for ESP8266 and ESP32 programming.
The programmer eliminates the need for creating a programming circuit on the ESP32 board, thereby reducing costs and enabling the creation of a smaller board. For a practical application of this, one may refer to the HA-DC motor design.
The product is equipped with a dual port, one for Arduino programming and the other for ESP8266/ESP32 programming. It also features a 3.3V/5V power switch, making it suitable for Arduino and ESP programming.
Please note that this product is designed for programming purposes only and should be used accordingly.
