    1. Introduction 1. Introduction The TWN4 MultiTech Nano Module is a configurable Reader/Writer of RFID transponders. It provides ports that can be connected to antennas operating at low (125kHz, 134.2kHz) and high (13.56MHz) frequencies. The Module can be accessed via a set of interfaces including USB, I2C, SPI, SAM, CAN, GPIO and COM (x2).
