DC-DC converter v2 is an open source PCB design by pioneers: a 2-layer, 53.3 × 27 mm board with 21 components (15 distinct parts). It is built around the C1849534, Anderson_Horizontal.

PiElectrical Work and Documentation

To Do: - Add battery calibration (Added switch, WIP for runtime) - Create DC-DC Converter (Work In Progress) - Fix battery shorting problem (Complete) - Remove power from data port, optional power using shortings (Complete) - Consider using different port for 5v (Kept as USB)

To Do: Large Revision - Find a switch rated for 50A @ 12VDC - Fuse each motor controller port with 7.5A slow-blow fuse (MC rated for 2x 3.5A motors) (Blows in 20Sec at 10A) - Add 40A slow-blow fuse for battery. (Blows in 5 min @ 50A, Blows in 20 sec @ 55A) (Battery Max is 55A) - Add 7.5A slow-blow fuse for 5V rail.…
