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 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
