Questions

How big is the BLE thingy PCB?

It measures 31.5 × 23.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the BLE thingy use?

31 parts, built around the ATTINY3216-SF, CR2032 and IRLML6401TRPBF. 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 BLE thingy KiCad files?

From the MarcelMG/BLE_thingy repository on GitHub, at the commit this page was made from: the board is hardware/BLE_thingy.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the BLE thingy design in my own project?

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