Very lightweight for sumo projects. Before this model, I was using nearly 2 times heavy gears (1 module) but with this combination robot's response time decreased (which is better) and no more sound like tractor, jejeje.

Motor's current slope is wonderfull. We were using old chinese motors which makes lots of electrical noises, resets... but this RE35s are completely insane. Very clean electrical interface. Same weight but power is nearly tripled! Just my problem is heating due to Arduino's low PWM frequency.

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! :)
