SWITCH SCIENCE ESPr Branch 32 (with Grove connector)

This development board integrates Espressif Systems' wireless communication module (Wi-Fi + Bluetooth) ESP-WROOM-32, a GROVE connector, a USB-serial conversion IC FT231XS, a 3.3V regulator, a reset switch, and an operating mode switch. The GROVE module can be used in the same way as the ESPr Developer 32. Regarding firmware rewriting for the firmware rewrite circuit on the ESP-WROOM-32 Wi-Fi module, the procedure for rewriting the firmware on the ESP-WROOM-32 is the same as that for the ESPr Developer 32. Regarding the external power supply terminal, there is an input terminal for external power supply next to the reset switch. It is left unmounted at the time of shipment, so please install a connector or terminal as needed. The input voltage is 4.0V to 6.0V.
