FaucetLED: common questions

What microcontroller does the FaucetLED use?

The FaucetLED is built around the STM32L052K8T6, from the STM32 family.

How big is the FaucetLED PCB?

The FaucetLED measures 34.5 × 28.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the FaucetLED?

39 components, from 25 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 FaucetLED design files?

From the ravotus/FaucetLED-pcb repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the FaucetLED design in my own project?

Yes, under the terms of its MIT license, which ravotus chose for the repository.

Can I test firmware for the FaucetLED without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
