Pico04: common questions

What microcontroller does the Pico04 use?

The Pico04 is built around the ATmega16U2-MU, from the AVR/Arduino family.

How big is the Pico04 PCB?

The Pico04 measures 38.3 × 41.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pico04?

33 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pico04 design files?

From the HumphreyKwok/pico04 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Pico04 design in my own project?

Yes, under the terms of its MIT license, which HumphreyKwok chose for the repository.

Can I test firmware for the Pico04 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.
