This single programmer will help you to program multiple microcontroller chips/boards. This board got dedicated slots for programming ESP32 Cam Board ESP32/ESP8266 Chip Arduino Pro mini Along with that, it also got a dedicated pinout of a regular TTL programmer using which you can program almost all the microcontroller chips. This simplifies the programming of the Microcontroller significantly since no manual reset and boot mode selection is needed when using with a common USB to serial interface. It’s a must have tool for all IOT and Electronics Engineers.
