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 insulated device: the power part is electrically insulated 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.

We need a 24V DC motor controller. Can you built a 24V version, if we order 10, 20, 50 or 100 items. If yes, how much will it cost?

@webjoy: contact support at Yoctopuce.

what are the correct enclosures for yocto-motor-dc and micro-usb-hub-v2

4 - martinm (Yocto-Team)Tuesday,may 02,2017 17H24

The Yocto-Motor-DC will fit in a YoctoBox-Watt-Transp (or black). No standard enclosure for the Micro-USB-Hub-V2 because it is supposed to be integrated into the enclosure of the contraption using it.

Yoctopuce, get your stuff connected.
