About the Osc dev m007 PCB

Osc dev m007 is an open source PCB design by OpenServoCore, published on GitHub under the Apache-2.0 license. It is a 6-layer board measuring 50 × 50 mm, with 78 components from 29 distinct parts.

Other key parts include the CH32M007E8U7. By type, the board carries 33 resistors, 25 capacitors, 4 connectors, 4 diodes, 3 transistors and 2 LEDs.

It belongs with the robotics & motion, sensors and power & battery designs in this gallery.

From the project

The goal of this project is to create an open servo controller board and firmware.

The development board for OpenServoCore's M007 servo brain. One chip - the CH32M007, 3 × 3 mm - contains the microcontroller, the motor gate driver, the current-sense amplifier, and the 5 V regulator. Add six small MOSFETs and it drives a brushed servo motor (SG90/MG90 class) or a small 3-phase BLDC, measures motor current, reads a position sensor, and talks on a single-wire bus.
