| Ref | value | type | package | quantity | Required? |
|---|---|---|---|---|---|
| C1-C9,C11 | 4.7u | capacitor | 0402 | 10 | yes |
| C10,C12 | * xx, yy | C0G capacitor | 0402 | 10 | yes |
| ST1 | STM32L432KU | Microcontroller | QFN32 | 1 | yes |
| N1 | AS3956-ATDM-S4 | NFC IC (SPI version) | MLPD 3x3 | 1 | yes |
| R1 | 500R | resistor | 0402 | 1 | no |
| L1 | CL-505S-X-SD-T | RGB LED | 0606 | 1 | no |
* C10 and C12 are tunning capacitors connected in parallel. I have not yet measured what the nominal value for them should be, but will be somewhere around 45pF.
