GB-BENCH-G1: common questions
What microcontroller does the GB-BENCH-G1 use?
The GB-BENCH-G1 is built around the PIC18LF45K50-I/PT, from the PIC family.
How big is the GB-BENCH-G1 PCB?
The GB-BENCH-G1 measures 100 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the GB-BENCH-G1?
98 components, from 52 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-BENCH-G1 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-BENCH-G1 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-BENCH-G1 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.
