yahboom AT8236 Dual H-Bridge Motor Control 3.6A

SKU CH-29K6-Y4D5H

Dual H-bridge board drives two DC or stepper motors at up to 3.6 A each with built-in over-current, short-circuit and thermal protection

  • Rated 3.6 A per motor with 6 A peak using dual AT8236 chips
  • Built-in over-current, short-circuit, under-voltage and over-temperature protection circuits
  • Compatible with 3.3 V and 5 V microcontrollers including Raspberry Pi, Arduino, STM32
  • Drives TT, 310, 520 and encoder motors via DuPont or PH2.0 connectors
  • Supports cascaded power supply for simultaneous dual-channel H-bridge control

Dual H-Bridge Motor Controller

The Yahboom AT8236 board drives two DC or stepper motors with a rated current of 3.6A per channel and a peak capability of 6A. It targets makers and engineers building Arduino, Raspberry Pi, STM32 or Jetson Nano projects that need reliable dual-motor control.

Current and Voltage Limits

Each channel handles up to 3.6A continuous and 6A peak while the on-board regulator accepts 5V or 3.3V logic signals. The design includes over-current, short-circuit, under-voltage lockout and over-temperature protection to keep the module safe under heavy loads.

Wiring and Common Issues

Motors connect via DuPont or PH2.0 headers and the board supports cascaded power for multiple modules. Builders must match the logic level to their microcontroller and ensure the supply can deliver the peak current; undersized power leads are the usual cause of voltage drop and thermal shutdown.

Questions about this item

Which version of the AT8236 board should I choose for a 3.6 A motor?

The module uses two AT8236 chips; each channel is rated for 3.6 A continuous and 6 A peak, so a single board handles two such motors.

What does the 3.6 A rating mean when the board is installed in a robot?

It means each motor can draw up to 3.6 A continuously without overheating, with brief peaks to 6 A, and the on-board protection prevents damage from stalls or shorts.

What logic levels does the AT8236 interface accept and what does that limit?

The inputs work with 3.3 V or 5 V microcontrollers such as Raspberry Pi, Arduino, STM32 or Jetson Nano, so any 3.3 V or 5 V PWM signal can drive the H-bridges.
