About the Ultramegausb atari st rpikbd PCB
Ultramegausb atari st rpikbd is an open source RP2040/RP2350 PCB design by trickydee, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 98.2 × 68.8 mm, with 9 components from 8 distinct parts.
Its main chip is the Pico, from the RP2040/RP2350 family. By type, the board carries 3 connectors, 1 IC and 1 diode.
It belongs with the iot & wireless and keyboards designs in this gallery.
From the project
USB & Bluetooth to IKBD Interface for Atari ST / STE / Mega and TT
This is useful if you have an Atari Mega ST that is missing its keyboard or if you just want to use modern keyboards, mice and joysticks with your ST.
The emulator provides the ability to use USB or Bluetooth keyboards, mice and joysticks / gamepads with the ST. You can also use original 9 pin Dsub 'Atari' Joysticks!.
Currently bluetooth requires a Pico 2w device - with this it is possible to Mix and Match any combination of USB, Bluetooth or 9 Pin Atari Joystick peripherals to create your perfect atari setup. If you just want USB support any Pico device will suffice.
