McGraw Tower LED Control Panel: common questions

What microcontroller does the McGraw Tower LED Control Panel use?

The McGraw Tower LED Control Panel is built around the PicoW, from the RP2040/RP2350 family.

How big is the McGraw Tower LED Control Panel PCB?

The McGraw Tower LED Control Panel measures 104.5 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the McGraw Tower LED Control Panel?

40 components, from 19 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 McGraw Tower LED Control Panel design files?

From the Aidan-McNay/chimes-leds 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 McGraw Tower LED Control Panel design in my own project?

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

Can I test firmware for the McGraw Tower LED Control Panel 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.
