STEVAL-GPT001V1 Thin-film solar smart watch based on SPV1050 energy harvester and battery charger

The STEVAL-GPT001V1 is a multi-sensor wearable unit hosted by a silicon strap and powered by the SPV1050TTR energy harvester and battery charger. Attached to the watch face and bands are 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, as well as increasing the autonomy of the system and charging the battery. The STEVAL-GPT001V1 cradle board is designed to accept the tiny STEVAL-STLCS01V1 SensorTile turnkey IoT sensor module, demonstrating the powerful processing capabilities of the ultra-low-power STM32L4 microcontroller and Bluetooth low energy connectivity based on the BlueNRG network processor, as well as a wide spectrum of MEMS motion and environmental sensors and a digital microphone.
