USER GUIDES
If you want to connect the fingerprint module to PC, you need to buy one UART to USB module. We
recommend you use Waveshare FT232 USB UART Board (micro) module.
If you want to connect the fingerprint module to development board like Raspberry Pi, if the working
level of your board is 3.3V, you can directly connect it to UART and GPIO pins of your board. If it is 5V,
please add level convert module/circuity.
