It has the ability to both read and write data in addition to reading the unique identifier (UID). All of the DLP-RFID2s electronics reside on a single, compact PCB, and all operational power is taken from one 3.0- to 5.0-volt supply. An external antenna can be connected via a standard u.fl connector or IO pin/pads.

The kit includes one RFID2 module, a DLP-RFID2U demonstration platform with an MSP430 microcontroller and LCD module, and a selection of small-format HF antennas as shown below: DLP-RFID2-EDK: DLP-RFID2U, DLP-RFID2 (shown mounted to the RFID2U) and Antenna Selection Source code for the MSP430 microcontroller on the DLP-RFID2U is available for download upon purchase of the kit. The source code was developed for use with the free version of Code Composer Studio from Texas Instruments. The DLP-RFID2U is also compatible with the Texas Instruments demonstration GUI. In this mode, data from the GUI passes through the DLP-RFID2U to the DLP-RFID2 module unchanged. (An electrical schematic for the DLP-RFID2U as well as a simplified schematic of the DLP-RFID2 are provided at the end of this datasheet.) The antenna selection is designed to provide the developer with a variety of sizes and shapes to assist in the selection of an appropriately sized antenna. (The size and shape of the antenna and RFID tags have a direct impact on the resulting read range.) The DLP-RFID2U module provides both standard SMA and reverse-polarity SMA connectors for connecting to the antennas. The antennas can be connected via either the provided SMA adapter or a user-supplied coax cable. While the DLP-RFID2 is designed to be surface mountable to the host PCB, it is not recommended that the user surface mount it to the DLP-RFID2U unless he or she intends to use only the external antennas. The ground plane on the bottom layer of the DLP-RFID2U PCB has an adverse effect on the read range of the internal antenna in the DLP-RFID2 module. If a developer wants to use the DLP-RFID2s internal antenna while mounted to the DLP-RFID2U, then the module should be mounted using through-hole headers to raise the module up off the RFID2U PCB. The performance of the DLP-RFID2s internal antenna will decrease as the distance between the two PCBs decreases due to the proximity of the ground plane in the DLP-RFID2U.
