The Yocto-Motor-DC device is a USB motor controller (ESC) for brushed DC motors. It can make your motor 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 with software. The configurable built-in safety system protects it 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-n and to a GSM network using a YoctoHub-GSM.
