Grove connector
The Seeedstudio Grove system is a seamless set of
open-source plug-and-play components. It simplifies
the study and electronic prototypes by proposing a
wide selection of sensors and actuators
You can find two types of grove connectors on the
board:
I2C
Analogic

Solar power
You can plug on the board a solar panel
This input has some limitations
Maximum voltage : 5.5V
Maximum current : 500mA
Maximum power : 2.5W
You can use a 1.5W Solar Panel for example

(1) Compile and check if the code has no error
Press the reset button twice within a second
to place the board into bootloader mode and
is expecting a new sketch
Select the ExpLoRer COM port assigned
(2) Upload the sketch to the board
(3) Open the Serial monitor for debugging
