- ## 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 |
- |:---:|:---:|:---:|:---:|:---:|
- | | s | s | s | s |
- | | s | s | s | s |
- | | s | s | s | s |
- |__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 |
- |:---:|:---:|:---:|:---:|:---:|
- | | s | s | s | s |
- | | s | s | s | s |
- | | s | s | s | s |
- | |__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 |
- |:---:|:---:|:---:|:---:|:---:|
- | |__X__| s | s |__X__|
- | | s | s | s | s |
- | | s | s | s | s |
- | | 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
