Questions
How big is the TeR ECU PCB?
It measures 101.8 × 67.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the TeR ECU use?
179 parts, built around the NEO-M9N-00B, TSR 1-2450, LIS3MDL and LM324. 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 TeR ECU KiCad files?
From the Tecnun-eRacing/TeR_ECU repository on GitHub, at the commit this page was made from: the board is HARDWARE/TeR_ECU/TeR_ECU.kicad_pcb and its schematic HARDWARE/TeR_ECU/CAN.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TeR ECU design in my own project?
Its repository states no licence, so its author keeps all rights: ask Tecnun-eRacing before reusing the design.
