RefleXion X65

Features

The RefleXion 65 is the perfect keyboard if you want a larger split ortholinear keyboard. With 70 keys, split in two 5x7 hands, and the option for a 2u thumb-key on each hand, it equals a 65% keyboard in number of keys. Adding an optional OLED and encoder per hand, you have plenty of keys to suit your every needs.

Add RGB to that, both the option for a discrete glow on the back & sides, or the option for a complete per-key matrix RGB, and if you want, you can combine the two as well, and you have plenty of options to customize the RefleXion X65.

With an RP2040 MCU and 2MB of on-board flash, you should have all the memory needed for advanced keymaps and/or RGB effects galore.

The RefleXion 65 is fully hotswap capable, and supports both the 2u key and the full 1u grid without any soldering changes, you can change layouts merely by reconfiguring the firmware and swapping the switches.¹

Main Features:

• QMK and VIAL compatible, fully programmable keyboard
• RP2040 MCU, Dual-core Arm Cortex M0+ processor, flexible clock running up to 133 MHz
  • 264KB of SRAM, and 2MB of on-board Flash memory
  • USB-C connector to host computer, (USB 1.1 device and host support)
  • Low-power sleep and dormant modes
  • Drag-and-drop programming using mass storage over USB
• Kaihl hot-swap sockets for Cherry MX compatible switches (3 & 5-pin)²
• Cherry Style PCB mounted stabilizers (Clip-in type preferred)
• USB-C Full duplex serial link (Uses USB 2.0 compatible cable)
• Full ESD protection on both USB host and Serial link connection (SRV05-4)
• Fully reversible PCB & Plates, identical for both hands
• Designed with a Sandwich-style plate/case as part of the design
• Two main layouts:
  • 2 x 5x7 - 1u grid with 70 keys
  • 2 x 5x7 - 1x2u per hand with 68 keys

Optional add-ons:

• Optional OLED Screen - One per hand
• Optional Rotary Encoder - One per hand
• Optional RGB - Use SK6803 Mini-E ONLY!!! ³
  • Glow (16 pcs needed)
  • Per-key (72 pcs needed)

These options requires additional components not included in this listing and sold separately.

Assembly

Little or no tools at all needed! The PCB can be delivered fully built and ready to use, with all the options you prefer. This requires added components to be purchased along with the PCB!!! Or as a basic Barebones keyboard with no OLED/Encoder/RGB added, and no need to solder unless you want to add these yourself. Or if you prefer, as a "DIY Kit" with soldering needed. In this case, all you really need to solder for a functional keyboard is the hotswap sockets, so it's very simple for a beginner to start learning. Other parts like the MCU and it's supporting components, as well as the USB ports, are already completed & tested.

Adding OLED's and Encoders to the PCB is also fairly basic with through hole components, and very suited to a beginner.

The optional RGB LED's needs to be soldered in place if used. These are a tiny bit more advanced than the sockets, but being winged, with the solder taking place outside the main body, they are more than possible for a beginner to solder with some care and patience.

To assemble the plates you will need a hex head screwdriver, for the spacers & bolts. (Size H1.5)

The Sandwich Case

RefleXion 65 is designed as a complete keyboard with a sandwich style case

The FR4 fibreglass plates used are quite stiff and give a good intermediate feel for keyboards, making it the ideal low cost material for a case. The PCB comes with the case plates as part of the kit, and you select how many OLED's & Encoders you prefer.

The 'case plates' are available in (black or) white, with either a blank upper shield, or with an OLED and Encoder based on your choice. The most 'average' option is probably to choose one of each, as you rarely have a need for more than one screen and encoder. But if you want too, you can certainly have two of each.

For now, there is no 3D printed case designed. I'm not the worlds best 3D designer myself. But if you want to make a case for this keyboard you are more than welcome too, 3D files (.STEP) of the PCB will be available to start from. And I will most certainly link & credit any designs from the GitHub pages, for other users to print.

What's in the Kit?

The DIY-Kit and prebuilt contain the exact same components.

Included Components

Required Accessories

These are the parts you need to complete a usable, working keyboard

• Key Switches, Cherry MX compatible (70 pcs )
• Key Caps, Cherry MX compatible (Set)
• Serial link cable - USB type C/C (USB 2.0 standard)
• Cable to your computer (USB type C/C or C/A)

Credits

This design was created by 'TweetyDaBird' Markus Knutsson, with a concept and continuous input from 'The Reflex' Pedro Quaresma, although with a fair amount of liberty taken accounting for hardware constraints.

¹ To insert or remove the stabilizer you will however have to remove the keys and split the plates.

² Please note that RefleXion X65 supports only Cherry MX type switches (3 & 5 pin), NOT Kaihl Choc, as they require a different PCB and plate design.

³ With the number of RGB LED's this PCB can support, it can easily overpower the USB ports ability to deliver power if SK6812 Mini-E type RGB are used, and can ultimately cause damage to the port in extreme cases. Please use ONLY SK6803 Mini-E, to keep power consumption at a somewhat sane level.

Normal handling time is 3 - 5 working days, not including build items (Those usually take 1 - 2 weeks).

Shipping is done with insured/signed for parcels, where no such service is available the parcel is sent as insured parcel, but may not be fully traceable the entire transit. If no insured or traceable service is available, parcels will be sent as uninsured/untraceable at the buyers responsibility. All of which is clearly stated on checkout.

All packets are represented to courier services and customs at their true sale value, and all responsibility for import fees, taxes and tariffs lie with the buyer.

The SE/EU "Act on Distance Contracts and Off-Premises Contracts (SFS 2005:59)" allows returns of the items in undamaged (unsoldered!) condition within 14 days of receiving it. Return shipping on returned items are the responsibility of the buyer.
