Yahboom AT8236 Dual H-Bridge Motor Drive Board development board

SKU CH-GYJM-PSS2T

Dual H-bridge board drives two DC or stepper motors at 3.6 A continuous, 6 A peak with over-current, short-circuit, under-voltage and over-temperature protection

  • CPU TypeOther
  • Drives two motors at 3.6 A continuous each using dual AT8236 chips
  • Peak current reaches 6 A per channel for short bursts
  • On-board 3.3 V and 5 V regulators with anti-reverse, over-current, short-circuit, under-voltage and over-temperature protection
  • Compatible with 3.3 V or 5 V logic from Raspberry Pi, Pico, Arduino, Jetson Nano, STM32
  • DuPont and PH2.0 connectors suit TT, 310 and 520 motors

Dual H-Bridge Motor Driver

This Yahboom AT8236 board drives two DC or stepper motors for robotics and automation projects. Each channel delivers a rated 3.6A with a 6A peak, making it suitable for TT, 310 and 520 class motors. It connects to 3.3V or 5V microcontrollers such as Arduino, Raspberry Pi, Pico, Jetson Nano or STM32.

Screw terminals and PH2.0 headers

Power and motor leads attach through screw terminals while logic signals use PH2.0 connectors or DuPont pins. The on-board 3.3V/5V regulator and anti-reverse circuit protect against wiring mistakes. Cascading multiple boards shares a single supply, but ensure the combined current stays within the source limits.

3.6A rated current per channel

The dual AT8236 chips set the continuous current ceiling at 3.6A per motor with a 6A peak. Builders needing higher sustained current or more than two independent channels will need a different driver architecture.

Questions about this item

How can I confirm the AT8236 board is working after wiring it to my microcontroller?

Apply power and send a PWM signal from the microcontroller; the connected motor should spin smoothly at the commanded speed and the on-board protection circuits should keep the chips cool even at the 3.6 A rated current.

What ships with the Yahboom AT8236 board and what must I source separately?

The package includes the motor drive module and a power cable; you must supply the microcontroller (such as Arduino, Raspberry Pi Pico or STM32), the motors (TT, 310 or 520 types) and the DuPont or PH2.0 wires to connect them.

Which version of the Yahboom dual H-bridge should I choose for a 520 motor drawing up to 6 A peak?

The single AT8236 version listed here handles 3.6 A continuous and 6 A peak per channel, matching the 520 motor’s requirements; no higher-capacity variant is offered in this listing.
