Cardio EVK User Manual for RT1025 Cardioid Evaluation Board
Purpose
The RT1025 is an integrated AFE solution for Heart-Rate monitoring and Biopotential measurements. The RT1025
integrates low noise voltage and current sensing channels and is capable of sensing ECG (Electrocardiography) and
PPG (Photoplethysmography) simultaneously. Richtek Technology developed an Android APP with the evaluation
board to evaluate RT1025 performance. This document describes the operation manual of Cardio EVK for RT1025
evaluation board.

Introduction
General Product Information
The RT1025 is an integrated AFE solution for Heart-Rate monitoring and measurements. The RT1025 integrates low
noise voltage and current sensing channels and is capable of sensing ECG (Electrocardiography) and PPG
(Photoplethysmography) simultaneously. The RT1025 has > 100dB dynamic range and can sense pulses accurately
by detecting the heart’s electric signals. The sampling rates of the high-precision voltage and current sensing
channels in the RT1025 are configurable between 64 to 4kHz. The RT1025 solution need only few discrete
components and is easy to use for low-power medical ECG/PPG, sports, and fitness applications. With high levels
of integration and high-precision voltage and current sensing channels, the RT1025 solution is suitable for scalable
medical instrumentation systems. The RT1025 is available in a 3.1mm x 3.4mm, 41-Ball, 0.4mm pitch, WL-CSP
package.
The Cardio EVK is an Android APP to evaluate RT1025 performance with the Cardioid evaluation board. The
evaluation board includes the RT1025 together with the BLE SiP and PPG modules to quickly evaluate the operation
and performance of the RT1025. The evaluation board number is PCB106_V1. For more information, please find the
related datasheet or application notes from Richtek website.

Usage with The Cardioid Evaluation Board
Measurement Procedure
The RT1025 supports the reading of samples and device status upon interrupt or via polling. It contains 4kB SRAM
for data buffering. The device is internally clocked to offer high-precision clock with external crystal. The flexible timing
control enable the users to control the PPG device timing for different application and to power down the device for
power saving. In order to achieve the high speed data acquisition, the RT1025 device was configured as a slave of
SPI mode. The Cardioid evaluation board is fully assembled and tested. The usage of the evaluation board was
shown in below figure.
1. Insert LIR2430 Battery in the battery case. The battery can be charged by applying 5V via the Micro USB port.
Once on, you should see a Red LED lighting for OK status.
If no light is present, check connections or try replacing the Battery with a fresh one.
If Red LED is flashing, check the I
2
C or SPI device correct connections.
2. Make sure the evaluation board connect to the Android APP for ECG/PPG measurement.
Make sure Bluetooth is enabled on the phone/tablet. (Not need to pairing)
Launch the “Cardio EVK” application on your phone/tablet.

Then, you will need to connect to the Cardioid evaluation board Hardware. Do this by selecting the “BLE
ICON” that shows up upon opening the android application. Select the evaluation board ID
(RTK_CARDIO_00XXXX) from pup-out menu for BLE paring.
After the Cardioid evaluation board BLE connection is successfully established, the “BLE ICON” will become
blue and the main GUI will launch.
Refer to detail “Description of ” from APP section for more information.
3. Put your fingers cover the VRLD and PPG sensor in the top, FR/FL in the bottom.

Select “PPG+ECG“ tab firstly, then press “Measure” to start PPG+ECG data acquisitions. Note that it may take a
while to get stable results. Press “Stop”, once you finish the measurement.
4. Check the measurement results. Press “SAVE” to store the measured data for analysis.
