It supports most DC geared motors and encoder speed measuring motors on the market with 5-12V. Onboard power supply anti-reverse connection protection circuit. The motor drive chip comes with protections such as short circuit, overcurrent, and overheating. The onboard 5V regulator circuit provides 3A high current output. Onboard 3.3V regulator circuit provides 500mA current output. Motor driver chip: AT8236 Power output: VM, 5V, 3.3V VM power supply range: 5V-12.6V 5V output current: 3A Single channel maximum current: 6A Hall signal Output : 0-3.3V Drive signal Input : 0-7V Motor drive chip protection: over-current protection, short-circuit protection, under- lockout, over-temperature protection detection: VM detection Expansion board protection function: input anti-reverse connection protection Function: It can drive two motors with Hall encoders at the same time, and at the same time, the 5V3A high current output supplies power to the main board.
