STMicroelectronics STEVAL-GPT001V1 Thin-Film Solar Smart Watch

STMicroelectronics STEVAL-GPT001V1 Thin-Film Solar Smart Watch is based on the Sensor Tile Cradle with SPV1050TTR energy harvester and battery charger. The device features a silicon band and watch face attached to a set of thin-film solar modules that are extremely efficient, especially in indoor environments. The development kit simplifies prototyping, evaluation, and development of innovative solutions. Additionally, the STMicroelectronics STEVAL-GPT001V1 increases the system's autonomy and charges the battery.

The STEVAL-GPT001V1 cradleboard is designed to accept the tiny STEVALSTLCS01V1 SensorTile turnkey IoT sensor module. This demonstrates the powerful processing capabilities of the ultra-low-power STM32L4 microcontroller and BLUETOOTH® low-energy connectivity based on the BlueNRG network processor. The STEVAL-GPT001V1 also showcases the abilities of the MEMS motion, environmental sensors, and a digital microphone.
