## Single- vs Dual-Encoder Support
|
||
|
|
|
||
|
|
The combined Cherry MX/encoder sockets allow single- and dual-encoder configurations.
|
||
|
|
|
||
|
|
The only rule when using two encoders is that there cannot be two encoders on the left side at once, or two on the right side.
|
||
|
|
This table shows where the encoders are in the switch grid ("X" for encoder, "s" for switch):
|
||
|
|
|
||
|
|
| C0 | C1 | C2 | C3 | C4 |
|
||
|
|
|:---:|:---:|:---:|:---:|:---:|
|
||
|
|
| |__X__| s | s |__X__|
|
||
|
|
| | s | s | s | s |
|
||
|
|
| | s | s | s | s |
|
||
|
|
|__X__|__X__| s | s |__X__|
|
||
|
|
|
||
|
|
- The three encoders in columns C0 and C1 are connected to each other
|
||
|
|
- The two encoders in column C4 are connected to each other
|
||
|
|
|
||
|
|
So, if doing dual encoders, one must be in column C4 and the other in either C0 or C1. Three or more encoders will not work.
|
||
|
|
|
||
|
|
The following sections describe the configurations that the default keymaps in QMK are designed for.
|
||
|
|
|
||
|
|
### Single-Encoder (Default Configuration)
|
||
|
|
|
||
|
|
In the default configuration, the encoder is in column 0, the bottom left corner below the Pro Micro. All other sockets are filled with switches.
|
||
|
|
|
||
|
|
| C0 | C1 | C2 | C3 | C4 |
|

|
|__X__| s | s | s | s |
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
### Dual-Encoder Bottom
|
||
|
|
|
||
|
|
One dual-encoder configuration has encoders in the bottom two corners of the 4x4 grid, and switches in the rest of the grid. The socket in column 0 is left empty.
|
||
|
|
|
||
|
|
| C0 | C1 | C2 | C3 | C4 |
|

|
|
|:---:|:---:|:---:|:---:|:---:|

| |__X__| s | s |__X__|
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
### Dual-Encoder Top
|
||
|
|
|
||
|
|
Another dual-encoder configuration has encoders in the top two corners of the 4x4 grid, and switches in the rest of the grid. The socket in column 0 is left empty.
|
||
|
|
|
||
|
|
| C0 | C1 | C2 | C3 | C4 |
|

|
| | s | s | s | s |
|
||

|
|
||
|
|
|
||
|
|
|
||
|
|
### No-Encoder
|
||
|
|
|
||
|
|
You may also choose not to use any rotary encoders if you like!
|
||
|
|
|
||
|
|
### Bill Of Materials
|
||
|
|
|
||
|
|
- Cherry-style mechanical switches
|
||
|
|
- EC11 rotary encoder with pushbutton (7-pin) - one or two depending on your desired configuration
|
||
|
|
- 1n4148 diodes (thru hole) - one per switch and rotary encoder (if using clickable encoder(s))
|
||
|
|
- 1x Arduino Pro Micro or pin-compatible ATmega32u4-based MCU
|
||
|
|
- (optional) 3x 3mm LEDs
|
||
|
|
- (optional) 3x 330 ohm resistors (for limiting current in LEDs)
|
||
|
|
- (optional) 6mm SPST switch for resetting MCU
