From the project
Brain board for the Open Duck Mini: Pi Zero 2W carrier, 14-servo STS bus, fused 2S power path in stitched copper zones (15-18 A battery side), USB-C charging with balancing, IMU. 4-layer KiCad 10 board, fit-checked in the duck's CAD.
The brain board for the Open Duck Mini: a Pi Zero 2W carrier with the 14-servo STS bus, a fused and switched 2S power path laid in stitched copper zones, USB-C charging with balancing, and the IMU.
Part of HeyPCB's open robot boards. Designed end to end with the HeyPCB method on KiCad 10 (headless pipeline, Freerouting 2.4.1); every number below is measured on the files in this repository. Mentions of ./run.sh, docs/rules/, blocks/ or parts/ refer to the heypcb-kicad SDK that produced them.
