Attach NFC

Can I attach NFC to metawear RPRO and integrate to get output from it?

Thanks

There are I2C and GPIO pins that you can use to communicate with 3V peripherals so as long as your NFC reader meets both criteria, it should work.

hi guys, I want to ask if there are more information on how to attach an NFC Reader/Writer

I want to interface to a "NXP PN532 NFC RFID Module V3" ( https://dangerousthings.com/wp-content/uploads/2013/12/PN532_-Manual_V3.pdf )

what's the best way to connect a PN532 with a MetaWear RG?

The RG board has SDA and SCL pins for I2C communication. Check the product specification PDF for the pin location

Hey guys, if anybody is wondering how to find the device ID of an I2C device on the I2C-BUS, here is small code snippet for Android:

The code iterates addresses from 1 - 127 and tries to write an read. If read is successful, then you have found the device ID.

Good luck.
