Test platform: common questions

What microcontroller does the Test platform use?

The Test platform is built around the PIC18F67J50, from the PIC family.

How big is the Test platform PCB?

The Test platform measures 143.5 × 110.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Test platform?

151 components, from 57 distinct parts. The full bill of materials is listed on this page.

Where can I download the Test platform design files?

From the kwiecinski/MultiChem-Battery-Tester repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Test platform design in my own project?

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

Can I test firmware for the Test platform 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.
