Kit overview
The
STEVAL-GPT001V1
kit is an add-on to the SensorTile cradle board with on-board charger for Li-Ion and Li-
Po batteries, a fuel gauge and a humidity and temperature sensor, housed in a watch-shaped silicon strap with
embedded PV solar panels.
The user can plug the
STEVAL-STLCS01V1
SensorTile module to the STEVAL-GPT001V1 via a dedicated
connector (CN2).
The kit has been designed for evaluation purpose and to support the development and prototyping phase of new
projects.

1.1.1.1
Watch-shaped silicon strap
The watch-shaped silicon strap has been designed to embed high efficiency flexible PV panels and to host both
the
STEVAL-GPT001V1
cradle board and the 100mAh battery provided in the STEVAL-GPT001V1 development
kit.
The PV panels are connected to the input stage of the STEVAL-GPT001V1 cradle board.
As shown in
Figure 1. STEVAL-GPT001V1 development kit
:
•
A PV panel is embedded in the front quadrant and can reach up to about 4 mW;
•
Two PV panels are embedded in the lateral straps and each of them can provide up to about 2 mW each at
1 Sun.
The four PV panels embedded in the strap are connected in parallel, so that, in total, they can supply up to 8 mW
at 1 Sun.
Three dedicated slots are available on the back and right side of the quadrant for direct access to the SWD, to the
micro-USB connector and to the ON/OFF switch (SW1).
