Wearable Demo Reference Design

This complete integration of sensors and connectivity options gives a strong reference design for wearable know-how. It ensures excessive efficiency and low energy consumption appropriate for varied purposes in movement sensing, environmental monitoring, and BLE connectivity.

The Wearable Demo reference design is powered by key elements from Atmel, that includes the Atmel SMART SAM L21 MCU primarily based on the Cortex-M0+ structure and the Atmel SMART Bluetooth resolution. Central to this platform is the ATBTLC1000, an ultra-low energy Bluetooth SMART System on a Chip that integrates a Cortex-M0 MCU, Transceiver, Modem, MAC, PA, TR Swap, and Energy Administration Unit (PMU). This versatile chip can operate both as a Bluetooth Low Power hyperlink controller or information pump with an exterior host MCU, or as a standalone purposes processor with embedded BLE connectivity and exterior reminiscence.

The platform’s core sensors are integral to its performance. The BHI160 sensor integrates a 6-axis IMU with the Bosch Sensortec Fuser core, providing a versatile, low-power resolution for movement sensing and sensor information processing. The BME280 sensor combines digital humidity, strain, and temperature sensing primarily based on confirmed rules. This sensor boasts a particularly quick response time for purposes requiring speedy context consciousness and maintains excessive general accuracy throughout a large temperature vary. Its strain sensor is an absolute barometric strain sensor recognized for its excessive accuracy, decision, and considerably decrease noise. The built-in temperature sensor is optimized for minimal noise and excessive decision, used not just for temperature compensation of the strain and humidity sensors but additionally for ambient temperature estimation. The VEML6080 is a sophisticated ultraviolet (UV) and ambient mild sensor. All sensors within the community connect with the SAM L21 by the SERCOM I2C interface.

It options the SAML21G18B processor at its core. It’s outfitted with an array of sensors, together with the BHI160 movement sensors (accelerometer and gyro) and the BME280 environmental sensors (strain, humidity, and temperature). The VEML6080 mild sensor measures ambient mild ranges. The BHI160’s built-in Fuser Core processes uncooked sensor information to generate digital sensor information, supporting capabilities reminiscent of recreation rotation vector, step detector, gravity, accelerometer, and gyroscope. The platform consists of the ATECC508A for cryptographic operations and LED indicators for operational standing show. Connectivity is supplied by the ATBTLC1000, an ultra-low energy Bluetooth® SMART (BLE 4.1) System on a Chip. Energy is equipped by a CR2032 coin cell, and programming is facilitated by the Atmel-ICE ARM 10-pin interface. The gadget is CE/FCC licensed and measures 40mm x 30mm, excluding the programming header extension.
