About the PCB MotorECU
PCB MotorECU is an open source PCB design by Knektium, published on GitHub under the CERN-OHL-1.2 license. It is a 2-layer board measuring 61 × 61 mm, with 27 components from 18 distinct parts.
Other key parts include the IFX9201SG, TLE4964, XMC1404_F064, TLE7251 and LM35-D. By type, the board carries 14 capacitors, 5 ICs, 4 connectors, 3 diodes and 1 resistor.
It belongs with the robotics & motion and sensors designs in this gallery.
From the project
The KiCad project for the PCB that is used as ECU for the Wolley Wheel and Fan modules.
This is the KiCad project for the PCB that is used as ECU for the Wolley Wheel and Fan modules.
It's a circular PCB that a brushed DC motor can be directly mounted on to be controlled by the driver and MCU onboard through CAN.
- Mabuchi RS-385PV-2465 - Mabuchi RS-365
Version 1.4: - Replaced the 4-pin connector with the new 5-pin connector. - Removed the battery power connector.
