Is the FireBeetle-ESP32 too big for your projects? Why not try our newly launched Beetle-ESP32! This Beetle-ESP32 Microcontroller is just 1.38”×1.34” and is a simplified version of FireBeetle-ESP32 - specially designed for electronic engineering fans and DIY lovers. It is equipped with 4 analog ports, 4 digital ports, UART and I2C interfaces, which would be a perfect (tiny) replacement of a FireBeetle-ESP32. This microcontroller enables users to directly burn programs via the onboard USB interface (micro-USB cable required). Meanwhile, Bluetooth and WiFi are integrated into the microcontroller for supporting more applications. With this Beetle-ESP32, you can easily build up your dream project!
