The RoRo80 is a custom-designed TKL PCB created for the keyboard enthusiast group "Pete". Named as a tribute to the legendary German debt counselor Peter Zwegat (a community inside joke). There have been multiple versions from the RoRo80, which all have been produced and tested! Here are the most recent solder and hotswap versions.
Hotswap:
Solder:
The RoRo80 comes in two different versions to suit your build preference:
| Feature | Hotswap Version | Solder Version |
|---|---|---|
| Switches | Kailh Hotswap Sockets | Solder |
| Indicators | Caps- & Scroll-Lock LEDs | None |
| Underglow | None | RGB Underglow (Bottom Side) |
| Bottom Row | 7U Tsangan Only | 7U Tsangan AND Standard Bottom Row |
- Compatibility: H87/H88 Form Factor
- Chipset: RP2040
- Mounting: O-Ring cutouts & versatile mounting support
- Connectivity: Breakable USB-C port (JST-header for Daughterboards)
- Software: Full QMK & VIAL Support
The RoRo80 uses the UF2 bootloader, making flashing as easy as using a USB thumb drive.
- First time: Plug the PCB in. A drive named
RPI-RP2will appear. - Flash: Drag and drop the
firmware.uf2file into that drive. - Subsequent times: Hold the BOOT button, press RESET twice, then release BOOT.
Tip
You can find the firmwares in the /firmware folder of this repository.
- Common: 7U Tsangan Bottom Row, Stepped CapsLock, Split Backspace & Split Right Shift, F12/F13
- ISO/ANSI: Both versions support ISO and ANSI
- Caps: Solder has both normal and stepped, Hotswap ONLY has stepped
Caution
Safety Warning: Removing the USB-C port creates FR4 (fiberglass) dust.
- Wear a mask and eye protection.
- Use pliers to carefully wiggle the port until it snaps off cleanly.
Here's a look at the PCB design from KiCad. It's where all the magic happens!
The project started in 2022 within the "Pete" enthusiast group. The name is a humorous nod to Peter Zwegat—because let's be honest: in this hobby, we are all just one group-buy away from needing professional financial advice.
The RoRo80 was developed to provide the group with a reliable, easy-to-configure RP2040 PCB that fits a variety of popular TKL cases, combining community memes with serious engineering. Two friends of the Pete Group, Roman and Rohaly, asked me to design a PCB for all of us. That's what I did and named the PCB after these two guys: Ro-Ro.
This project is part of the open-source keyboard movement. Thanks to Gnarsch aka. Roman for the permission.
WE LOVE OPEN SOURCE.
