P1110-EVB
Evaluation Board for P1110 Powerharvester Receiver
Description:
The P1110-EVB contains an evaluation board and antennas to test and develop with the P1110
Powerharvester Receiver. The P1110 converts RF energy (radio waves) into DC power which can be
stored in a battery or capacitor, or used to directly power a circuit.
Items included:
1 Evaluation Board for P1110 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 P1110 product datasheet from www.powercastco.com/documentation to learn
about the specific I/O and functions of the P1110.
2. Connect one of the antennas to the SMA connector (J1) on the evaluation board, or connect J1
directly to RF test equipment. See datasheet for maximum input power.
3. Adjust switches S1, 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)
