2.1 Functional Overview

The TWN4 MultiTech 3 BLE is a complete RFID Reader system that requires a 5V or 3.3V power source
and connection to a host to work. The majority of the circuitry responsible for processing the RFID card
information and executing the module firmware is shielded as shown on Figure 2.1. The device can be
connected to the host via USB interface. A more generic breakout interface to the main controller is
available; its pinout is shown in Table 2.2. The TWN4 MultiTech 3 BLE also offers a SAM slot and a
speaker on board.
The TWN4 MultiTech 3 BLE can interact with the User via Bluetooth Low-Energy interface. This develop-
ment pack contains documentation on BLE protocol and API implemented on the module.
