# Bill of Materials
This is a list of every part needed to assemble one Tangara.
| Component | Manufacturer + part number |
|-------------------------------|----------------------------|
| Mainboard PCB | See `tangara-mainboard` |
| Faceplate PCB | See `tangara-faceplate` |
| Touchwheel cover (0.6mm FR4) | See `touchwheel-cover` |
| 15 pos 0.5mm pitch FFC cable | Samtec FJH-15-R-03.00-4 |
| 4x 6mm M2 standoffs | Wurth 970060244 |
| 4x 14mm countersunk M2 screws | |
| 4x 8mm countersunk M2 screws | |
| Case top half | See `case-v2` |
| Case bottom half | See `case-v2` |
| Switch cover | See `case-v2` |
| 2x Button covers | See `case-v2` |
| SD card cover | TBD |
| 3-pin 2200mAh 604560 LiPo | EcoCell LIP2-001 |
We're currently finalising our production v2 case design, including the SD card
cover. Full sources for these will be available once they're finished.
For the battery, note that a 2-pin cell may be compatible if R1 on the mainboard PCB is populated with a 10k 0603 resitor. We recommend sourcing a suitable battery locally, as international shipping of LiPo batteries can be difficult.
