Robot Power Simple-H Dual Channel H-Bridge Controller 20A, 5-28V for 3-28V Logic
Supports 5V to 28V supply voltage
Drives 20A continuous, 25A with fan
Features heatsinks for heat dissipation
Accommodates complex microcontrollers
Includes current sense outputs
The Robot Power Simple-H Dual Channel H-Bridge Controller 20A, 5-28V for 3-28V Logic is a versatile and robust circuit designed for driving DC motors and other DC loads within a range of 6V to 28V. It supports a wide array of command sources, from simple switches to complex microcontrollers, allowing for flexible integration into various systems. The Simple-H HV version accommodates up to 28V input signals, maintaining the same circuit board footprint and mounting pattern as its counterparts.
This controller does not include on-board logic for interpreting commands, necessitating an external signal source to convert command inputs into the necessary switching signals. This design choice enables control via simple pushbuttons or advanced microcontrollers, including PCs through parallel or USB ports. The HV version features indicator LEDs with a constant-current driver, ensuring consistent output regardless of signal voltage and eliminating input signal loading.
The Simple-H is engineered to deliver reliable performance, with current ratings sustained over extended periods, unlike some competitors. It employs heatsinks and heavy copper areas for efficient heat dissipation, with the option to add a cooling fan for enhanced performance. The controller's design allows for configuration as a single full H-bridge or two independent half-bridge circuits, which can be combined for increased current handling. Mounting provisions for a standard 12V 50mm square computer cooling fan are included to maximize cooling efficiency.

If you are not satisfied for whatever reason with a Product you bought on the Site, it is possible to return it for refund within 30 days from the date you received it unless otherwise indicated in the Product listing. You must first advise the Vendor associated with your order in your account to obtain a return authorization (‘’RA’’) number before returning a Product. (‘’RA’’) numbers are valid for 30 days, within which time the returned Products should be received by the Vendor. No returns will be accepted without having previously obtained an (‘’RA’’) number. The Product must then be returned in its original packaging (in perfect condition for resale) with its receipt and your (‘’RA’’) number. Reimbursement will be denied for any Products which do not conform to the above mentioned conditions.
Build-it-yourself Robot Parts are not refundable once assembled. Robots & Kits requiring assembly or soldering are also not refundable once assembled, soldered or modified in any way. All sales of robotic software and apps are final and cannot be refunded or exchanged. Returns are not accepted on special orders and clearance items except when they are found defective, in which case the Product may be repaired or replaced at the Vendor’s discretion. 20% Restocking fees may apply if you are returning a large quantity of the same Product that was ordered specifically for you from the manufacturer.
Please note that all items will be reimbursed within 7 to 14 days of receiving the Product (shipping fees excluded). You must also cover the cost of returning the Product. Shipping fees will only be refunded if the return is a result of a shipping error on our part. Cleaning fees of USD 100 may also be charged if a domestic robot is returned and has not been properly cleaned.
