Panel main: common questions

What microcontroller does the Panel main use?

The Panel main is built around the PIC16F877A, from the PIC family.

How big is the Panel main PCB?

The Panel main measures 191.7 × 104.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Panel main?

112 components, from 35 distinct parts. The full bill of materials is listed on this page.

Where can I download the Panel main design files?

From the CarnivalBen/golden-key repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Panel main design in my own project?

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

Can I test firmware for the Panel main without the hardware?

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