M5Stack BALA2 Fire Self-balancing Robot Kit

The BALA2 Fire (Bala is short for ‘Balance’) is the second generation of the

M5Stack

balancing robot series. The BALA2 Fire is a Self Balancing Robot consisting of an M5Stack Fire and two wheels with DC motors. The base uses an STM32F030C8T6 as the main control and has a two-way encoding motor driver and a built-in 1200mAh battery.

This robotics product comes with preloaded software including 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 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 the M5Stack Fire through I2C(0x3A).
