Questions

How big is the DynamicBrakeGrid PCB?

It measures 175 × 125 mm and has 4 copper layers, 1.64 mm thick.

What parts does the DynamicBrakeGrid use?

111 parts, built around the ISO1042BDWVR, ARDUINO UNO R3, RFMM-0505S and LM358DR. 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 DynamicBrakeGrid KiCad files?

From the datacrystals/BikeV2 repository on GitHub, at the commit this page was made from: the board is ChargerControlBoard/DynamicBrakeGrid.kicad_pcb and its schematic ChargerControlBoard/Connectors.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the DynamicBrakeGrid design in my own project?

Its repository states no licence, so its author keeps all rights: ask datacrystals before reusing the design.
