1) Introduction
1.1) About the Arrow Next-Biometrics Mezzanine
The NB-2023-S2 shield board with assembled NB-2023-S2-VAIX (SPI) fingerprint module is a fingerprint development shield for the DragonBoard 410c development board by Arrow Electronics. The mezzanine includes a software Development Kit (SDK), which can be downloaded from NEXT Biometrics Support Portal https://support.nextbiometrics.com/. The NB-2023-S2 shield board has been paired with the DragonBoard 410c development board and used as a one solid piece of hardware (However, other 96Boards may be compatible).

2) Pin Mapping
NB-2023-S2-VAIX fingerprint module utilizes SPI interface and two GPIO pins to communicate with the DragonBoard 410c.Table 1 shows the mapping of fingerprint module pins to LS expansion connector on the board.
| Pin | Name | LS Connector Pin | Function |
|---|---|---|---|
| 1 | MOSI | 14 (APQ GPIO_16) | SPI Data – Slave In |
| 2 | MISO | 10 (APQ GPIO_17) | SPI Data – Slave Out |
| 3 | GND | 1, 2, 39, 40 | Ground |
| 4 | SCLK | 8 (APQ GPIO_19) | SPI Clock |
| 5 | GND | 1, 2, 39, 40 | Ground |
| 6 | nAWAKE | 24 (APQ GPIO_69) | Finger Detect |
| 7 | nSS | 12 (APQ GPIO_18) | SPI Slave Select |
| 11 | nReset | 26 (APQ GPIO_12) | Reset |
