Maxim Reference Design Speeds Development of Wearable Heart-Rate and Pulse-Oximetry Monitors

Developers of heart rate and blood oxygen (SpO2) monitors can now accelerate their efforts using the ultra-small MAXREFDES117# reference design from Maxim Integrated Products, Inc. (NASDAQ: MXIM).

This optical heart-rate module reference design incorporates red and infrared LEDs, a sensor, power subsystem, and logic level translation. Measuring 13mm x 13mm, this tiny, low-power board can be placed on a finger or earlobe to accurately detect heart rate and SpO2 via personal wearable devices. The module works with both Arduino® and ARM® mbed™ platforms for ease of design, testing, and system integration, and includes eight "tap pads" for quick electrical connection to a development platform and/or wearable garment.
