TrainDepartureBoard-Discord: common questions

What microcontroller does the TrainDepartureBoard-Discord use?

The TrainDepartureBoard-Discord is built around the R7FA4M1AB3CFM, from the Renesas family.

How big is the TrainDepartureBoard-Discord PCB?

The TrainDepartureBoard-Discord measures 68 × 68 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TrainDepartureBoard-Discord?

55 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the TrainDepartureBoard-Discord design files?

From the AaronJackson/TrainDepartureBoard-Discord repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the TrainDepartureBoard-Discord design in my own project?

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

Can I test firmware for the TrainDepartureBoard-Discord without the hardware?

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