Bear-sized optical gesture instrument firmware.
Bearcv-10hp main dualMCP4728 routed DRC pinremap revc is an open-source printed circuit board by actuallysparky, from the actuallysparky/bearamin repository on GitHub, published under the MIT licence. It is a 4-layer board of 55.4 × 126.1 mm with 128 parts on 76 nets, routed with 1,472 tracks and 159 vias.
It is built around the SN74AHCT125PWRE4, CC0603KRX7R9BB104 and AVR-M1608C220KT2AB, with the BAT54S-7-F-79, RT0603BRD0710KL and RT0603BRE0714K3L among its other parts. Its parts include 4 ICs, 2 diodes and 2 fuses. It belongs with the ESP32 boards of this library.
The canonical publication hardware is the v6 sidecar board:
bearamin-dpt-sensor-v6.kicad_probearamin-dpt-sensor-v6.kicad_pcbThe PCB contains the XIAO ESP32-S3 Wi-Fi sidecar, ESP32-S3 MatrixCore, VL53L7CX 8x8 sensor connection, DPT link, and power components. It has no retired single-point sensor footprint or connection.
The current board is routed and KiCad reports no unconnected pads. Its current DRC report contains 14 warnings for local footprint overrides and silkscreen size/overlap, so review and resolve those items before fabrication.
The v6 release is board-authoritative and does not attach the older v5 schematic. The v5 board, its schematic, earlier revisions, autorouter intermediates, and generated fabrication exports remain local design history and are not part of the publication bundle.

It measures 55.4 × 126.1 mm and has 4 copper layers, 1.6 mm thick.
128 parts, built around the SN74AHCT125PWRE4, CC0603KRX7R9BB104, AVR-M1608C220KT2AB and BAT54S-7-F-79. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the actuallysparky/bearamin repository on GitHub, at the commit this page was made from: the board is bearamin-lite/hw/bearcv-10hp/bearcv-10hp-main_dualMCP4728_routed_DRC_pinremap_revc.kicad_pcb and its schematic bearamin-lite/hw/bearcv-10hp/bearcv-10hp-main_dualMCP4728_routed_DRC_pinremap_revc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
