Questions

How big is the Evse PCB?

It measures 42.5 × 62.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Evse use?

92 parts, built around the OPA171AIDBV, PEM1-S12-D12-S, A5950GLPTR-T and ADS1118IDGS. 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 Evse KiCad files?

From the Tinkerforge/evse-bricklet repository on GitHub, at the commit this page was made from: the board is hardware/evse.kicad_pcb and its schematic hardware/evse.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Evse design in my own project?

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