Let me introduce you the Quadrant, a 5x14 ortholinear keyboard, inspired by the Plaid and The_RoMac.
I genuinely adore the aesthetic of these through hole boards, and I wanted to give them a little design twist. These two projects encouraged me to get familiar with designing PCBs and create my own one. It was a real fun and I would like to share with you the final result, fellow clackers, not only in the form of pictures but also in the form of a product.
Group Buy is closed! You can find the Google form here: https://forms.gle/SpGum41mFL4UQW576
Thank you for the participants, guys! I didn’t expect to close the GB this fast, but all slots had been reserved. I will send out the invoices on Saturday (UPDATED from “in the next 14 hours”)..
The long wait is over, the Quadrant is coming to town on 19th of December! The GroupBuy will start at 19:00 CET (UTC+1):

  • There isn’t any MOQ, but the maximum number of slots is 45 for this round. The sale is going to be FCFS, and ends on the 2nd of January or until the maximum number of orders is reached.

  • The price of the kit is 50USD (including PayPal fees), plus shipping cost, which will be calculated individually according to the shipping address.

  • The invoices will be sent out via PayPal as soon as possible after the GB is closed. You will have 48 hours to complete the payment otherwise the slot will be raffled among the additional participants who left out the sale.

  • After all payments are collected, I will immediately order all the parts for the kits. It will take approximately 8 weeks to begin the shipping.

  • The source files of the keyboard and the layered acrylic case will be uploaded to Github in the following days of GB closing.

    Features of the keyboard:

  • ortholinear layout

  • 5x14 matrix

  • Elite-C microcontroller support

  • QMK firmware

  • MX-style (PCB mounted only) and Kailh Choc switch compatibility

  • rotary encoder support: on 1x1 and 1x5 of the matrix (only one of the 2 sockets can be used at a time, because they share the same traces for data)

  • WS2818B LED strip support

  • one programmable LED (Caps Lock LED as default)

  • reset button

  • PCB colour variants: black (white silkscreen) and white (black silkscreen)

  • two sided graphics on the bottom PCB

  • aesthetically placed diodes

  • transparent polycarbonate shield to protect the components from any damage and dust

  • estimated price: 50USD + shipping
    The construction of the Quadrant follows the usual “main PCB - standoffs - bottom plate” structure, without any plate. Therefore, it accommodates only PCB mounted switches.

    The 5x14 matrix gives you the opportunity to use the extra columns for additional modifiers, macro keys or full “ISO” support to the fellow Europeans in the community.
    You can see the layout options below:

    The kit contains:

  • 1pc top PCB (it only supports MX style, PCB mount switches and Kailh Choc low profile switches)

  • 1pc bottom PCB

  • 70pcs 1N4148 THT diodes

  • 1pc 3mm LED (cool white)

  • 1pc resistor for LED

  • 1pc 6x6mm tactile push button

  • 10pcs 6mm standoffs

  • 4pcs 10mm standoffs

  • 12pcs M2x4mm screws

  • 4pcs M2x6mm screws

  • 4pcs M2x12mm screws

  • 1pc transparent polycarbonate shield

  • 4pcs rubber feet
    Extra thoughts:
    The source files for the Quadrant PCB will be uploaded after the GB ends.
    I designed an acrylic sandwich case for the keyboard as well. The files for laser cutting will be released after the GB ends.
    The small companion on the left side of the Quadrants is called Aphellion, and it’s a 1x4 macropad with rotary encoder and OLED screen support, dedicated to media control. This project is still in development and I will share all the details with you as soon as I figure out how to display the data of currently playing media files.
    Timeplan:

  • 27_08_2019: IC released

  • 07_09_2019: 1. update: The PCB was adjusted according to the feedbacks

  • 18_09_2019: PCB v1.1 finalized and ordered a small batch of sample

  • 04_10_2019: ordered a prototype of the acrylic case

  • 11_10_2019: the prototype of the acrylic case arrived, but I’m missing the correct standoffs, so I have to wait for them

  • 18_10_2019: v1.1 PCBs arrived, the adjusting of the firmware just started

  • 23_10_2019: the firmware is almost finished, the only thing left is test of the RGB lighting

  • 07_12_2019: the firmware is finished, announcement of the Group Buy

  • 19_12_2019: starting the Group Buy
    Please feel free to share your ideas and thoughts with me here or in the IC form!

PCB colour variants (the black and the white verions got most of the votes by far in the IC, therefore there will be available only these two colors in the GB)
There were two versions of the main PCB (the bottom PCB is the same):

  • the T2.0 version supports Teensy2.0
  • the E-C version supports Elite-C (standard Pro Micros are not supported because of their fewer pins)
    It was not decided which version would be the final product, but the most votes from the IC went to the popular Pro Micro clone with USB Type-C.
