Description

BALA2Fire is short for 'Balance', as its name suggests, it is the second generation of M5Stack balancing robot series. BALA2Fire is a Self Balancing Robot consisting of M5Stack Fire and two wheels(DC motors).The base uses STM32F030C8T6 as the main control and has a two-way encoding motor driver and built-in 1200mAh battery.

This robotics product comes with preloaded software. A self-balancing robot application which balances the robot vertically using a closed-loop algorithm. You can program it to automatically move around through programming, or you can combine Wi-Fi to develop remote control functions.

This Robot is controllable by a Smartphone device or a Transmitter. The BALA2 base contains a wealth of interfaces. In addition to the conventional PortB and PortC, it also supports 8-channel servos, of which 4 channels can be directly connected, and the remaining 4 channels need to be connected from the inside of the base. Even if you have never attempted such a balancing robot program, you can quickly get the hang of it and control it through UIFlow. The self balancing robot uses data from the Accelerometer and Gyroscope to correct its orientation and position.The 2 DC driver module communicates with M5Stack Fire through I2C(0x3A).

Caution: While using PSRAM, you cannot use PortC
