What is Pico Terminal?
Pico Terminal runs on the Raspberry Pi Pico 2W with a 320×240 display, turning it into a full-featured Digimon virtual pet device. It reads your physical DM20, Pendulum, DiM and other 2-prong / IR Digimon devices, stores your monsters in the Digimon Bank, raises them in the Ranch, and battles opponents sourced from a 1,182-sprite library.
Built on the WiFiCom foundation by the WiFiCom & dmcomm community. Ranch, Bank, DigiDB, asset bundle system, and Read Device features added by YNK Tech. This project exists because of your support.
Downloads
All builds are for the Raspberry Pi Pico 2W (RP2350) running CircuitPython 10.x. See the setup guide below.
Official / OG CircuitPython
Download the official CircuitPython 10.x firmware for RP2350 from the
CircuitPython website. Flash the .uf2 first, then copy the
Pico Terminal bundle on top.
Quick Setup

Community
Pico Terminal builds on the WiFiCom project and the dmcomm protocol library, created and maintained by the WiFiCom community. The Ranch, Bank, DigiDB, ASB bundle system, and Read Device features were added by YNK Tech.
If you want to support continued development, Ko-Fi goes directly to hardware, hosting, and more device compatibility testing.
Feedback & Bug Reports
Found a bug? Want to request a feature? Have a build that won't load? Drop it in Discord or open a GitHub issue — either works.
Best for quick questions, sharing builds, and showing off your monsters.
Best for reproducible bugs, crash traces, and feature requests that need tracking.
When reporting a crash: copy the REPL output from your Pico's serial terminal
(tio /dev/ttyACM0 or Mu Editor) and paste it in the issue.
Tracebacks tell us exactly where things went wrong.
