project data, records & publications

AVR (ATMEGA328P) programmer via RP2040-ZERO dev board on a custom in-house built PCB using a homebrew software toolchain.

The embedded RP2040-Zero board comes pre-flashed with the necessary ICSP firmware. The Python script linked below can be used to transmit a compiled ihex file from your computer to an inserted ATMEGA328P chip over USB (-C).

22001: common questions

What microcontroller does the 22001 use?

The 22001 is built around the ATmega328-P, from the AVR/Arduino family.

How big is the 22001 PCB?

The 22001 measures 78.7 × 52.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 22001?

8 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the 22001 design files?

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

Can I use the 22001 design in my own project?

The repository has no license, so all rights stay with marian-scientific. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 22001 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.
