About the Amigahid pico PCB

Amigahid pico is an open source RP2040/RP2350 PCB design by borb, published on GitHub. It is a 2-layer board measuring 61.7 × 72.4 mm, with 57 components from 9 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. By type, the board carries 33 resistors, 17 transistors, 6 connectors and 1 IC.

It belongs with the retro computing, keyboards and dev boards & breakouts designs in this gallery.

From the project

Use USB input devices on Amiga computers, using the excellent Raspberry Pi Pico as a USB-to-bitbang adapter.

please note: the interesting stuff goes into the development branch, so if main seems slow, check it out.

amigahid-pico uses the rp2040 microcontroller (e.g. the raspberry pi pico) in a carrier board to attach usb input devices to a standard amiga without the need for a usb stack on the amiga itself.

it currently supports keyboards and mice and provides connection via the internal keyboard connector, the rj11/din socket on big-box amigas, and via the controller ports.

Amigahid pico: common questions

What microcontroller does the Amigahid pico use?

The Amigahid pico is built around the Pico, from the RP2040/RP2350 family.

How big is the Amigahid pico PCB?

The Amigahid pico measures 61.7 × 72.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Amigahid pico?

57 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the Amigahid pico design files?

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

Can I use the Amigahid pico design in my own project?

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

Can I test firmware for the Amigahid pico without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
