Motor drivers
About the Motor drivers PCB
Motor drivers is an open source PCB design by manyetox, published on GitHub under the CC-BY-NC-4.0 license. It is a 4-layer board measuring 25 × 27 mm, with 25 components from 13 distinct parts.
By type, the board carries 10 capacitors, 10 resistors and 3 connectors.
It belongs with the robotics & motion and sensors designs in this gallery.
From the project
Source-available modular mobile carrier for autonomous photonics experiments using ESP32 control, optical flow, IMU sensing and magnetic wheel encoding.
Platform: V2 Board revision: MDI-R2.0 Status: validated; current PCB: 4 layers, approximately 25 × 27 mm
This daughterboard combines low-speed differential-drive actuation with inertial sensing.
- TC78H651FGN dual H-bridge motor driver - BNO086 9-axis smart IMU - SPI-oriented IMU interface signals - separate motor output pads
The design is intended for the low-speed DC-gearmotor V2 drivetrain rather than the V1 stepper/flexure architecture.
