Usage Guide
The P9415-R Evaluation board allows for demonstration of the performance and functionality of the P9415-R
device in a lab bench test environment. For complex or electrically sensitive situations, it is recommended to use
the reference layout to integrate this design into the final system to eliminate hardware limitations or signal
degradation introduced by long leads.

Kit Hardware Connections for Rx Mode
Follow these procedures to set up the kit as shown in Figure 2.
1. Set up the P9243-GB Evaluation Board (or other transmitter board) according to the board’s user manual
and apply power.
2. Place the P9415-R-EVK Board on the transmitter coil surface with the coil back facing upwards. P9415-R-
EVK PCB boards act as a spacer between Tx surface and Rx coil.
3. Verify that the green LEDs on both kits are illuminated, indicating that power transfer has been established.

Start Guide for Rx Operation
Place the bottom side of P9415-R EVK onto P9243-GB Tx or other WPC certified Tx unit. P9415-R EVK
includes a 58 × 58 × 0.3 mm TRx coil assembly. The charging pad may be a pre-powered and may be powered
after placing the Rx coil on Tx charging pad.
Verify that green LED on P9415-R is illuminating and measure Rx output voltage at the VOUT test point to
ground (GND). Up to 1A load may be connected between VOUT and the GND terminals. For convenience and
measurement accuracy, two test points have been placed which allow for kelvin voltage sensing of the output
voltage to omit conduction losses during evaluation (VOUT and GND). These should be utilized when performing
efficiency measurements. The I2C dongle connector J1 can be used to interface with WPD-USB-DONGLE
dongle for programming the user configurable design parameters and it can be used to monitor the system
status, mode, operating frequency, voltage and current.
