AVRForth: common questions

What microcontroller does the AVRForth use?

The AVRForth is built around the ATMEGA8A-PU, from the AVR/Arduino family.

How big is the AVRForth PCB?

The AVRForth measures 203.2 × 135.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AVRForth?

69 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the AVRForth design files?

From the oco2000/AVRForth repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the AVRForth design in my own project?

Yes, under the terms of its GPL-3.0 license, which oco2000 chose for the repository.

Can I test firmware for the AVRForth 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.
