Isolated USB motor controller (ESC) for brushed DC motors 3…18V / 20A, with integrated current, voltage and temperature probes.

SKU: MOTORCTL Categories: ,


The Swiss-made Yocto Motor DC device is an USB motor controller (ESC) for brushed DC motors. It can make your motors go forward, reverse or even brake. Applied power is controlled by pulse width modulation (PWM) with a resolution of 0.1%.

Power supply voltage range is 3 to 18V. Without any cooling but natural convection, it can withstand 10A continuous. With proper cooling, using a small fan for instance, it can withstand up 20A continuous. 30A short bursts are allowed.

The Yocto Motor DC features integrated voltage, current and temperature probes, to easily monitor vital parameters from software. The configurable built-in safety system protects against overheating, low power supply and excessive currents. A red LED signals abnormal conditions.

It is also an isolated device: the power part is electrically isolated from the USB part. The driving PWM frequency can be configured from 250 Hz to 32 KHz. The device includes a configurable startup booster to help motors to start at low RPMs.

This device can be connected directly to an Ethernet network using a YoctoHub Ethernet, to a WiFi network using a YoctoHub Wireless-g, it can even be connected to a GSM network thanks to the YoctoHub GSM.

USB cables and enclosure to be ordered separately from MOTORCTL Yocto Motor DC.
