Spider evaluation board is available for ANDY100 UHF RFID IC, which harvests RF energy from commercial UHF RFID readers and communicates with them using EPC C1G2 standard commands. ANDY 100 IC, included with evaluation board, also includes SPI master to drive sensors while keeping tag plus sensor device battery-free. Additionally included start-up circuit lets developers work directly with SPI sensors or connect MCU of choice for further processing.
