From the project

Medidor de potência para bicicleta, aberto do extensômetro ao pod: torque por ponte de classe transdutor no braço do pedivela, BLE Cycling Power e ANT+ Bicycle Power. Firmware Zephyr, placa e case gerados por programa. CC BY-NC 4.0.

Os geradores do KiCad 8: esquemático, placa, roteamento, verificações, 3D e desenhos. É a cadeia do ciclocomputador (hardwaregnssbike/cad/), portada em 2026-09-27 com o nome de projeto pmeter, as tabelas desta placa e três correções no roteador que esta placa, mais densa e mais estreita, obrigou a fazer. Nada aqui é desenhado à mão: cada arquivo .kicad_*` sai de um script, e cada script diz de que documento ou ficha tirou cada número.
