Wireless sensor node demonstrator hosts MAX32600 “wellness MCU”

May 18, 2015 // By Graham Prophet
Maxim integrated has posted details of its MAXWSNENV demo kit that provides a platform evaluating the capabilities of the environmental sensor version of Maxim’s wireless sensor node (WSN). The kit provides a foundation for the Internet of Things (IoT) applications.

The WSN board includes a microcontroller, Bluetooth Low Energy (BLE) transceiver, multiple environmental sensors and coin-cell holder. The WSN kit also includes a programming adapter compatible with the ARM mbed HDK specification.

The microcontroller is Maxim’s MAX32600, with the company terms its Wellness Measurement Microcontroller, with optimisations for biological sensing. It is an ultra-low-power ARM Cortex-M3 design with wellness sensor analogue front-end and advanced hardware security. Operating at up to 24MHz it includes 256 kB of flash memory, 32 kB of SRAM, a 2 kB instruction cache, and integrated high-performance analogue peripherals. In addition to the free tools provided by Maxim, the MAX32600 supports the Embedded Workbench from IAR Systems.

Features of the development kit include;

Microcontroller plus BLE transceiver provides a convenient development platform

On-board sensors for temperature, ambient light, humidity, and barometric pressure measure environmental data

Low-power operation extends battery life

ARM mbed-compatible HDK interface provides quick connection to toolchain

General-purpose pushbutton switch and tri-color LED allow for real-time input and feedback

On-board battery holder provides convenient and replaceable power source

Use the kit, Maxim suggests, to evaluate project in area such as;

Blood glucose metering

Galvanic skin response measurement

Pulse oximetry measurement

Wearable medical devices
