BalancerCarrier
About the BalancerCarrier PCB
BalancerCarrier is an open source PCB design by natehorst240-sketch, published on GitHub. It is a 4-layer board measuring 50 × 53.6 mm, with 31 components from 23 distinct parts.
Other key parts include the FeatherS3[D], LM1815MX/NOPB, SN74LVC1G132DBVR, SN74LVC1G123DCTR and IIS3DWBTR. By type, the board carries 11 capacitors, 11 resistors, 5 ICs, 2 connectors, 1 switch and 1 LED.
It belongs with the power & battery, rf & radio and test & measurement designs in this gallery.
From the project
Hobby helicopter rotor-balancing instrumentation. KiCad 10 projects plus ESP32-S3 firmware.

Open the projects in KiCad 10.0.3 or later. They use the KiCad 10 file format and KiCad 9 will not open them.
Both boards are routed. On the main board SYS, SYSSW, BAT and USBVBUS had been routed across In2.Cu, which is the +3V3 plane; those tracks were removed on 2026-09-18 so the plane is whole again, and those four nets were then re-routed on the outer layers (PR #7, merged with Rev G on 2026-09-19). The Rev G connections (U7 pass-through, R39) are routed too. BalancerREF/review/drc-review.rpt…
