BLINKY-KEYCHAIN: common questions

What microcontroller does the BLINKY-KEYCHAIN use?

The BLINKY-KEYCHAIN is built around the XIAO-RP2040-SMD, from the RP2040/RP2350 family.

How big is the BLINKY-KEYCHAIN PCB?

The BLINKY-KEYCHAIN measures 71.8 × 68.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BLINKY-KEYCHAIN?

8 components, from 4 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the BLINKY-KEYCHAIN design files?

From the Ka6667/BLINKY-KEYCHAIN repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the BLINKY-KEYCHAIN design in my own project?

The repository has no license, so all rights stay with Ka6667. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the BLINKY-KEYCHAIN without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
