Board recommendation ?
#1
Hello,

I have 8 wooden doors and I want to install a 12v electric lock in each one and also a NFC card reader in each one.

To power the electric locks I can use a kincony board with 8 relays, but each card reader needs to be connected via SPI or with I2C

Is there a kincony board that can resolve this needs?

Edit:
problem is that the card readers might have the same I2C address, probably I do need a I2C multiplexor TCA9548A?

Also, if I want to use Kincony F series I see that the I2C port is utilized by a LCD screen… how can I overcome this difficulty?

Thanks
