FIRE
Description
M5Stack FIRE Kit is a upgrade from the Gray kits,except the 9-Axis IMU sensor. It provides more
hardware resources : 16M Flash + 4M PSRAM , enhanced Base (M5GO Base and M5GO CHG Base), larger
M5Stack Docs
battery, etc.
With a IMU posture sensor, you can include posture detection in your work : accelerated speed,
angulation, and trajectory deection. You can make relative products like sports data collector, 3D remote
gesture controller and more.
FIRE is M5 Core device. Its modular, stackable, scalable, and portable device is powered with an ESP-32
core, which makes it open source, low cost, full-function, and easy for developers to handle new product
development on all stages include circuit design, PCB design, software, mold design and production.
