Dear Sirs, 
 
I need to connect a Fingerprint module SPI to an Orange Pi 4G-IOT. 
 
The Fingerprint module SPI is a Next Biometrcis model NB2023-S2. You may check its brief at the following link:  
 
Product Brief NB-2023-S2-V.pdf 
 
I may provide more information about this Fingerprint module. 
 
The avaliables Android ROMs for 4G-IOT were not compiled with SPI support, besides the board has two SPI ports. 
 
I need an Android 8 ROM for Orange Pi 4G IoT with SPI support (compiled). 
 
Dear friends, I can pay 300 USD for this ROM. Please, may anybody help me? 
 
Thank you in advance.
