Introduction

The 

STEVAL-GPT001V1

 is an add-on development kit for the STEVAL-STLCS01V1 SensorTile module.

The kit and the module create a whole system which represents a multi-sensor IoT node with increased energy autonomy
thanks to the power harvested from thin-film solar modules (under indoor or outdoor lighting conditions) and conditioned to
recharge the battery through the 

SPV1050TTR

 energy harvester and battery charger.

The STEVAL-GPT001V1 kit consists of a watch-shaped silicon strap embedding three PV panels, a cradle board (which is an
evolution of the STLCR01V1 SensorTile Cradle board) whose core product is the SPV1050TTR and the power management
section to recharge a 100 mAh Li-Po battery.

The SPV1050TTR optimizes the energy harvested from the PV panels, thanks to the embedded MPPT algorithm, and
recharges the battery while guaranteeing over-voltage and under-voltage protection; the harvested energy allows a longer
system autonomy and makes available a 3.3 V LDO output to supply the 

STEVAL-STLCS01V1

 SensorTile module.

The customized STSW-GPT001V1 software offers a complete framework to build a typical multi-sensor node application and to
monitor battery charge, system autonomy, recharge time and the energy stored.

The firmware can be uploaded onto the STEVAL-STLCS01V1 SensorTile module via the STEVAL-GPT001V1 cradle board
SWD connector.
