P1110-EVAL-01
Lifetime Power Energy Harvesting Development Kit for Battery Recharging
User Manual
Overview
The Lifetime Power Energy Harvesting Development Kit for Battery Recharging is a complete
demonstration and development platform for recharging batteries wirelessly from RF energy (radio
waves). It is designed to be used with an App and is configured for out-of-the-box operation.
The battery recharging boards utilize the P1110B Powerharvester Receiver, which converts RF energy
into DC power. Either the PowerSpot transmitter or TX91501-3W transmitter is the source of RF
energy, with both operating at 915MHz. Other RF energy sources operating from 850-950 MHz can also
be used as power sources (UHF RFID readers for example). The battery recharging boards receive the RF
energy, convert it to DC, and charge the onboard batteries.
The kit also includes two BLE radio boards that can be attached to the battery recharging boards. When
used in conjunction with the watch or credit card battery recharging boards, the measured charge
current and battery voltage are transmitted via Bluetooth to a mobile device and displayed in the
included App. This enables the user to test both configurations on battery recharging boards
simultaneously.
The P1110-EVB is included in the kit as well. The P1110-EVB contains an evaluation board and antennas
to test and develop with the P1110B Powerharvester Receiver. Like the Battery Recharge Boards, it
converts RF energy into DC power which can be stored in a battery or capacitor, or used to directly
power a circuit. It includes two different antenna configurations.

Qty Item Description
1 PowerSpot Transmitter 4-watt, 915 MHz transmitter for power and data with integrated 8dBi
(TX-91502-ASSEMBLY) antenna and power jack.
1 Power and Data 3-watt, 915 MHz transmitter for power and data with integrated 8dBi
Transmitter antenna and two power jacks. Sends a pre-programmed transmitter
(TX91501-3W-ID) ID that is received by the P1110B Powerharvester component and can
be decoded by an external MCU.
1 P1110 Evaluation Board Evaluation board (Rev. B) for P1110B Powerharvester Receiver. This
(P1110-EVB) board has an SMA connector to attach the antennas and a 10-pin
connector for plug in test board WSN-EVAL-01 (not included).
1 Patch antenna 915MHz directional antenna with 120-degree reception pattern
(PA-915-01) (included with the P1110-EVB evaluation board).
1 Dipole antenna 915MHz omni-directional antenna with 360-degree reception
(DA-915-01) (included with the P1110-EVB evaluation board).
1 Watch Shaped Battery Flexible watch-shaped board that contains Powercast energy
Recharging Board harvesting technology to recharge the connected 100mAh lithium ion
(EVAL-FLEX1-PCB) battery. Status LED will turn on when the battery is fully charged.
1 Credit Card Shaped Rigid credit-card sized board that contains Powercast energy
Battery Recharging Board harvesting technology to recharge the connected 13mAh lithium ion
(EVAL-CC1-PCB) battery. Status LED will turn on when the battery is fully charged.
Some units are equipped with a switch to disconnect the battery. It
must be turned on when to charge the device.
2 Radio Boards Radio board that receives the current charge and voltage data from
(EVAL-RB1-PCB) the connected battery recharge board and transmits that data via BLE
to the App. Each radio board has its own unique ID and is powered
from an included CR2032 coin cell battery.
