Portable oximeter
The portable oximeter is based on MindMotion MM32 Microcontrollers:
- Cortex-M0(+) operating at a frequency of up to 72MHz, allows blood oxygen saturation signal acquisition, algorithm operation and LED display operation
- Provide the high performance 1Msps 12b ADC, improve the storage and processing for the optical sampling data, provide high efficiency of sampling and the high-resolution calculation
- 100K Flash erase cycles, for user data storage, saving the system BOM cost by reducing EEPROM
- Powered by 2x AAA alkaline batteries, MM32F00xx and MM32F01xx MCU’s low power consumption modes can support up to 36 hours of continuous working time
- MM32L0130 ingrates Segment-LCD controller and low to 100nA in standby mode, can reduces the system power consumption to most extent, and provide the long lift-cycle and ease-to-use experience
