Redesign Panda Black Revival + Port Firmware City G7
Projeto de Bruno Costa (kriptomad): manter a panda preta (STM32F4) viva e levar o Honda City G7 2023 (Brasil) para o openpilot/flowpilot, mais o redesenho da placa com STM32H725 (Hybrid Panda, CAN-FD). Nada foi validado em hardware ou no carro ate agora. Documentacao em PT-BR (ASCII).

Questions
How big is the HarnessBox PCB?
It measures 30.5 × 30.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HarnessBox use?
13 parts, built around the RJ45-DB-101PWB, BAV21W RHG and FSV20100V. 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.
Where can I download the HarnessBox KiCad files?
From the kriptomad/PandaH7Openpilot repository on GitHub, at the commit this page was made from: the board is 01_BASELINE/original_copy/HarnessBox/kicad_project/HarnessBox.kicad_pcb and its schematic 01_BASELINE/original_copy/BlackPanda/kicad_project/BlackPanda.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HarnessBox design in my own project?
Its repository states no licence, so its author keeps all rights: ask kriptomad before reusing the design.
