Description

M5Stack FIRE Kit features an ESP32 Core, 16M Flash + 8M PSRAM, 9-Axis IMU sensor (6-Axis posture acceleration measurement + 3-Axis magnetic measurement), power management IC, speaker, microphone, and a 2 inch 320x240 LCD screen. The middle part is called M5GO base which provides a 500 mAh battery, M-BUS socket, LED bar and three more GROVE Ports. The bottom part is a charge table, which can be connected to the M5GO base via POGO pins.

Wifi Issues due to GPIO15

When the M5GO bottom is attached, GPIO15 (side lights pin) needs to be setup as an output pin, otherwise Wifi will fail to connect frequently. If you do not want to setup the side lights component (to save memory, for example), you can use the following alternative instead:
