GB-MBCTEST: common questions

What microcontroller does the GB-MBCTEST use?

The GB-MBCTEST is built around the PIC18LF45K50-I/PT, from the PIC family.

How big is the GB-MBCTEST PCB?

The GB-MBCTEST measures 51.4 × 61 mm, has 2 copper layers and is 1 mm thick.

How many components are on the GB-MBCTEST?

32 components, from 22 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 GB-MBCTEST design files?

From the Gekkio/gb-hardware 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 GB-MBCTEST design in my own project?

Yes, under the terms of its CC-BY-4.0 license, which Gekkio chose for the repository.

Can I test firmware for the GB-MBCTEST 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.
