About the Board v2 before connector move

Board v2 before connector move is an open source PCB design by gizatt, published on GitHub. It is a 2-layer board measuring 55 × 65 mm, with 25 components from 15 distinct parts.

Other key parts include the LD33V, MPU-6050-BREAKOUT and DRV8313PWP. By type, the board carries 12 capacitors, 5 connectors, 4 ICs, 2 resistors, 1 switch and 1 diode.

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

From the project

For ease of control tuning, I chose a main board with Bluetooth Low-Energy (BLE) support, and written a companion program that connects to the robot and allows parameter updates. This program is currently very primitive but it beats reprogramming or having it drag around a serial

For ease of control tuning, I chose a main board with Bluetooth Low-Energy (BLE) support, and written a companion program that connects to the robot and allows parameter updates. This program is currently very primitive but it beats reprogramming or having it drag around a serial cable (which interferes with control).

I mostly rely on SimpleFOC for the actual FOC implementation, and took their advice on sensor and drive chip choice. I'd like to dive deeper into controlling these motors better -- for example, trying to compensate for cogging torque to get smoother operation - but I have more…
