Microchip’s pulse oximeter reference design demo board helps designers develop a low-cost, low power handheld or wearable pulse oximeter with user interface which is capable of measuring both heart rate and blood oxygen level. It can be used to start development of a hospital or clinical pulse oximeter design, but it can also be used as a starting point for the development of a wearable activity tracker design that can measure heart rate and blood oxygen level.
