Cheap & powerfull. I am using this at my RC model boat for nearly 3 month. No problem.

I am planning to order 100 pcs for our local competition. Are there any more discounts? We are ready to share Jsumo as a our sponsor. Please.

I am using this board with MikroC, easy to use. I suggest for all robot guys. Mosfet side is very helpful for triggering selenoids from board. At 2nd design I can suggest you may add more voltage outputs. Adding 8 sensor makes little cable harness problem.

Very useful controller, I used for sumo robot. Jsumo team send me free code. Very basic. What I liked most. Ready made sensor pins for 12V.

I was designing myself before. Later I gave a chance to this controller. We are using them for our 5 minisumorobots. Very clean designed. At first understanding code was hard but later I used to. For next projects I will contiune to buy.

Before them, I was using Pololu motors, they are nearly 2 times bigger and I use this 300 Rpm at 4S (2+2) lipo total 16,8Volts, doesn't burn.

I used it in my mini sumo robots.The response time of the sensor is very good, the opponent can detect immediately.

I used it in our own competitions. Better than lots of wheels models. We want bigger sizes too! :)

We use them at minisumo and sumo robots. One tip, Don't use them as analog. Black & White is very sharp transition for directly using with digital inputs.

Greetings from Mexico! The information inside is really enlightening. I would recommend to all competitors for better sumo robots.
