SUMO:BIT - Sumo Robot Expansion Board for micro:bit
Want to participate in a Sumo robot competitions but you’re a complete beginner? Or want to try controlling a Sumo robot using a micro:bit mainboard? SUMO:BIT is here to the rescue!
Program your SUMO:BIT with Microsoft MakeCode Editor graphical programming interface. Just install SUMO:BIT MakeCode Extension and you may start to code your projects. If you’re a beginner, you can start with the block programming mode; simply drag, drop & snap the coding blocks together. For more advanced users, you can easily switch into JavaScript or Python mode on MakeCode Editor for text-based programming.
SUMO:BIT Features:
- Designed for micro:bit, beginner friendly, easy drag and drop code with MakeCode for autonomous Sumo robot
- Co-processed by Raspberry Pi RP2040
- Detachable MD13S motor driver, replace without hassle whenever needed
- Powerful Motor Driver that supports up to 13A (continuous) motors and 30A peak current.
- Mode interchangeable without reprogramming.
- USB host for wireless USB joystick, easily interchangeable between autonomous and remote-controlled within seconds!
- Onboard motor alignment adjust and calibration
- 4-way DIP switch for 16 different winning strategies!
SUMO:BIT Specifications:
- Power Input Voltage (LiPo Battery):
- Min: 7V
- Max: 25V
- Motor PWM Frequency (when connected with MD13S): 20KHz
- Maximum DC Motor Current each Channel (when connected with MD13S): 13A
- Peak Motor Current each Channel (when connected with MD13S: 30A ⚠️must not exceed 10 seconds⚠️
- USB Host Output Voltage: 5V
