+**Essentials**:
+| **Item**                        | **Count** | **Note** |
+|---------------------------------|-----------|----------|
+| Keyboard PCB                    | 2         |          |
+| Nice!Nano                       | 2         |          |
+| 12 pin headers and sockets      | 4         | You can use through-hole diode legs as pins. Sockets spacing: 2.54mm, Socket height: Using minimal height sockets might not leave enough room to mount the battery under the MCU. 3DS1002-01-1*20V13-JK by CONNFLY are a good choice, but you can also use lower ones and longer legs instead. Spiltkb has a good [guide on mounting](https://docs.splitkb.com/hc/en-us/articles/360011263059).  |
+| LiPo battery (301230)           | 2         | 110mAh   |

+| Keycaps                         | 56        |          |
+| Kailh Choc hotswap sockets      | 56        |          |
+| Encoder EVQWGD001               | 2         |          |
+| Diodes 1N4148W                  | 58        | for each key + encoder |
+| Buttons                         | 2         | reset buttons; 2 pins through-hole, tactile, 3x6x4.3mm |
+| Slider Switches                 | 2         | on/off switches; SMD, C128955 |
+| USB-C Cable                     | 1         | for copying the firmware
