Demonstration platform boosts Bluetooth sensor node development

Designed for what is claimed to be the world’s lowest-power Bluetooth low energy sensor node, Microchip offers a demonstration platform with the low power BTLC1000-cerified module, a Smart SAM L21 Cortex-M0+microcontroller, Bosch sensor technology and software.

For low power and smaller form factors, the kit integrates the BTLC1000-MR110CA BLE module which uses the world’s lowest power and smallest Bluetooth low energy solution, delivering at least 30% more power savings compared to existing solutions, says the company. It is packaged in a small 2.2 x 2.1mm wafer level chipscale package (WLCP).  The SAM L21 achieves an ULPBench score of 185, the highest recorded score for any Cortex-M0+ while running the EEMBC ULPBench, says th company, with power consumption down to 35microA/MHz in active mode and 200nA in sleep mode. According to the company, using these components, it is possible to increase battery life up to four times longer than current solutions on the market.

The kit also includes the latest generation Bosch 6-axis motion (BHI160) and environment (BME280) sensors that can be used for a variety of sensing applications. The platform includes source code, hardware design files, user guide and Android application source code.

Possible applications are the development of personal health and fitness, indoor navigation, wearables, gaming, context awareness and augmented reality, using sensors for a more immersive experience.
