Razer Orbweaver plug and play RP2040 MCU replacement for QMK
« on: Sat, 07 December 2024, 10:49:05 »
I would like to formally introduce something that I've been working on for a little while now. It was driven by the desire to have an viable alternative to Razer Synapse.

The Razer Orbweaver RP2040 plug and play MCU replacement.



This mod is heavily based on the initial work and research of a_marmot and his excellent thread from a few years back. See https://geekhack.org/index.php?topic=119396.0 for details.

I had a couple of issues with this earlier approach.  It requires modification to the Orbweaver shell. It involves several bundles of wire. And finally, it does not retain the functionality of the 3 status LEDs on the thumb section of the device.

This is where my board comes in.

Features
  • Plug and play - reuses all the original connectors without modification
  • Mostly non-destructive - installation requires trimming one mounting post
  • Restores the 3 indicator LEDS
  • Fully supports RGB and RGB Matrix animations

The first prototypes arrived and have been tested and I am in the process of tidying up the QMK firmware for the device.





Future Plans

So what next for this project? Trying to decide if the demand is there to do a small production run of these.  If you're interested let me know.  Costs should be around £20 + postage but this could come down if enough people would like one.

I also hope to make a couple of addons for this mod.
  • USB C detachable cable
  • Additional button carrier PCB - for things like layer and mode switching - this would require case modification
  • Replacement switch PCB - possibly hot-swappable switches

I am interested. Does your 20 pound price include full assembly, or just the PCB and components? How much approximately to ship across the pond to the US?

Fully assembled and programmed.

I'd need to check postage costs but shouldn't be too much. Less than $10 for sure.

Finalised the firmware and have had it merged into the main qmk_firmware repository.
