Bala2-Fire
SKU:K014-E
Description
Bala2-Fire is a balancing car application. This product is a self-balancing robot composed of M5Stack Fire and the BALA2 motor base. The base uses STM32F030C8T6 as the main controller and is powered by dual N20 encoder geared motors. It has a built-in 1200mAh battery. The name "BALA" comes from the abbreviation of the word "Balance", and this is currently the second-generation product.
The BALA2Fire base includes rich interfaces. In addition to the standard PortB and PortC, it also supports 8 servo channels, of which 4 channels can be connected directly, and the remaining 4 channels need to be extended from inside the base. You can control it to move freely through programming, or develop remote control functions via WiFi. Even if you have never worked with balancing car programs before, you can quickly complete programming and control it through UiFlow.
By default, the balancing car application is pre-installed at the factory. During operation, it uses a PID closed-loop algorithm to maintain vertical balance, and uses accelerometer and gyroscope attitude data to correct its direction and position.
