60percent (quite original, I know) is a 3D printed, handwired keyboard powered by ZMK inspired by the tokyo60. If you are new to handwiring, worry not.
| Part | Qty | Description |
|---|---|---|
| Challenger 840 BLE | 1 | Micro controller board with Bluetooth LE |
| MX-style switches of your choosing | 60 | I used Outemu Lemon/Limes. |
| 1N4148 Diodes | 60 | You need these for handwiring |
| Keycaps | 1 set | You will need a 7u spacebar in the set |
| Cherry stabilizers | 1 set | Requires 1 x 7u and 2 x 2u |
| Wires | - | I used wrapping wires |
| M2 x 6mm hex female-to-female brass standoff (spacer) | 5 | This is what supports/holds down the plate and the case together |
| M2 x 12mm countersunk screws | 2 | Case-side that goes with the brass standoff |
| M2 x 10mm countersunk screws | 3 | Case-side that goes with the brass standoff |
| M2 x 6mm flat top screws | 5 | Plate-side that goes with the brass standoff |
| M2 x 6mm countersunk screws | 4 | Holds the MCU down |
| M2 hex nut | 4 | Holds the MCU down |
| 3.7v LiPo Battery | 1 | You'll have to source this locally, as batteries aren't shipped overseas usually |
| JST 2.0 PH Connector | 1 | Required if the battery doesn't come with compatible connection |
Note: The countersunk screws are all the same link. The screws, standoff, and the nut are from the same seller. These are all links that I bought from to build my keyboards.
Below, you can find the rows and columns I wired to the Challenger 840 BLE and the way I wired my columns. I only drew the columns, probably more useful flipped (as the backside of the board is wired), which is also included. I highly encourage you to map your own columns, as I'm worried that it'll be harder to follow mine.
