J67G: common questions

What microcontroller does the J67G use?

The J67G is built around the ATmega32U4-MU, from the AVR/Arduino family.

How big is the J67G PCB?

The J67G measures 285 × 95.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the J67G?

156 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the J67G design files?

From the Salicylic-acid3/PCB_Data repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the J67G design in my own project?

Yes, under the terms of its MIT license, which Salicylic-acid3 chose for the repository.

Can I test firmware for the J67G without the hardware?

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