This product is a self-balancing robot composed of the M5Stack Gray and the BALA2 motor base. The base uses the STM32F030C8T6 as the main controller, powered by two N20 encoded reduction motors, and has a built-in 1200mAh battery. The name "BALA" comes from the abbreviation of "Balance," and this is the second-generation product. The BALA2 base includes a rich set of interfaces, supporting 8 servo motors in addition to the regular PortB and PortC, with 4 interfaces directly connectable and the other 4 needing to be extended from inside the base. You can program it to move freely or develop remote control functions with WiFi. Even if you have never worked with balancing car programs before, you can quickly complete programming and control it using UiFlow. The product comes pre-installed with a balancing car application, using a PID closed-loop algorithm to maintain vertical balance during operation, and utilizes accelerometer and gyroscope attitude data to correct its direction and position. Features 9-axis attitude sensor Dual-wheel drive, PID control balance Grove expansion interface (PORTB/PORTC) 8 servo motor drives, 4 external, 4 internal Supports WiFi, programmable Built-in speaker Supports TF card expansion Compatible with LEGO I2C communication: 0x3A Development platforms MicroPython UiFlow Arduino Includes 1 x Gray 1 x Bala2 Base 2 x HY2.0-4P connection cables (20cm) 4 x wheel hub connectors 2 x LEGO arms 1 x hex key 1 x USB Type-C cable (1m) Applications Balancing car Specifications Specification Parameters MCU STM32F030C8T6 ESP32 240MHz dual-core, 600 DMIPS, 520KB SRAM, Wi-Fi Flash/RAM 16MB Flash LCD 2-inch, 320x240 color TFT LCD, ILI9342C Speaker 1W-0928 MEMS BMM150+MPU6886 Motor drive HR8833 Base controller STM32F030 Interfaces GROVE I2C x 1/UART x 1/GPIO x 1/SERVO x 4(+4 Extendable Channels) Battery capacity 1200mAh Net weight 157.0g Gross weight 337.0g Product Size 54 x 54 x 65mm Packaging dimensions 100 x 100 x 100mm Casing material Plastic Learn and Documents → DOCUMENTS Show more
