P2110-EVB Powercast

P2110-EVB Evaluation Board for P2110 Powerharvester Receiver Description: The P2110-EVB contains an evaluation board and antennas to test and develop with the P2110 Powerharvester Receiver. The P2110 converts RF energy (radio waves) into DC power and stores it in a capacitor to provide an intermittent, regulated voltage output. Items included: 1 Evaluation Board for P2110 Powerharvester Receiver (see description on next page) 1 915 MHz PCB dipole antenna (see description below) 1 915 MHz PCB patch antenna (see description below) Note this kit needs to receive power from an RF source such as a transmitter or test equipment. Instructions: 1. Download the P2110 product datasheet from www.powercastco.com/resources to learn about the specific I/O and functions of the P2110. 2. Connect one of the antennas to the SMA connector (J1) on evaluation board, or connect J1 directly to RF test equipment. See datasheet for maximum input power. 3. Adjust switches S2, S3, and S4 to desired settings. See descriptions on next page. 4. Place evaluation board on flat surface and connect test meters as desired. 5. Turn on the source of RF energy (e.g. Powercast transmitter, test equipment, other transmitter) Support: Website: Evaluation Board Component Description S1 Not used S2 Switch for output power LED (power sent to illuminate LED D1) CHG (power sent through switch S4 for charging capacitor C6 or ext. battery BT1) MEAS (use with test points and in-line meter for current measurement) S3 Switch for DSET selection. When enabled, RSSI is available through DOUT. VOUT (Not used) EXT (Enabled by external source through DSET EXT test point) OFF (Normal charging operation) S4 Switch for powering external circuit through BT1 (BAT) C1 Optional output filtering for VOUT 10 uF recommended (see datasheet) C2 Optional output filtering for RESET 0.1 uF recommended (see datasheet) C3 Capacitor (1000 uF) C4 Capacitor (user selectable) C5 Capacitor (50 mF) C6 Not used JP1 Selection for capacitors C3, C4, and C5 D1 LED for visual indication of power output R1 Resistor for LED (D1) R2 Connection from VSET to GND to increase output voltage above 3.3V (see datasheet) R4 Connection from VSET to VOUT to decrease output voltage below 3.3V (see datasheet) R5 Not used R6 Not used BT1 External circuit connection J1 SMA connector for antenna or RF input (add DC block for DC short antenna) U2 P2110 Powerharvester receiver (see datasheet for pin descriptions) P2110-EVB, Rev A 2010/5 2010 Powercast Corporation Page 2
