The US082-OB1203EVZ board enables quick prototyping of the OB1203 multi-channel light sensor (LS/CS), proximity sensor (PS), and photoplethysmography sensor (PPG) in a custom system design. The board provides a standard Pmod™ Type 6A (Extended I2C) connection for the on-board sensor to plug into any desired MCU evaluation kit with a matching connector.

The US082-OB1203EVZ features Pmod connectors on both sides of the board to allow additional Type 6/6A boards to be connected in a daisy-chained solution with multiple sensors on the same MCU Pmod connector. Thanks to the standard connector and software support, the US082-OB1203EVZ is ideal for Renesas’ Quick-Connect IoT to rapidly create an IoT system.


  • OB1203 sensor sample mounted:
    • Fully integrated and trimmed module, including two LEDs, 250mA maximum drive current, and photodetectors for SpO2 measurements
    • High lux accuracy over different light sources, with absolute sensitivity of 0.06 lux to > 150000 lux
    • Four parallel channels for measuring red, green, blue, and clear with accurate Correlated Color Temperature (CCT) and CIE 1931 XYZ (RGB) color measurement
    • Object movement detection (in/out)
  • Standardized Type 6A Pmod connector supports I2C Extended interface
  • Dual connectors allow pass-through signals for daisy-chained solutions
