firebeetle esp32 has made a special hardware design for Arduino IDE. You can download it without manually switching boot mode. It supports Arduino, IDF (linux), micropython etc. Moreover, FireBeetle made a pin mapping for Arduino IDE. It can be configured with Dx transport, is compatible with Arduino UNO and reduces the entry barrier.
The small size and high performance make FireBeetle the ideal solution for IOT low power consumption projects.
