1. Is this just an ad?

2. The name is likely to conflict with this established product: https://www.leaflabs.com/maple/

3. You don't seem to say how much Flash it has.

  Are you sure? yes | no

Hi, It's a real project, so we want to share with people. And we also hope some persons can use it to develop. The idea is come from leaflabs maple board. The dimension & interface are same completely. But It's a ESP32 board.

The Flash size is 4MB. Because of  no ESP32 chip, we are using ESP-WROOM32 of ESpressif.

  Are you sure? yes | no

The Arduino IDE can program the ESP8266 directly, however it is frequently more difficult, whereas the ESP32 is simple to program.
