Gravity: I/O Expansion Shield for
Pyboard SKU:DFR0577
Introduction
Gravity: I/O Expansion Shield for pyboard is an multifunctional expansion shield specially designed
for pyboard v1.1. It is compatible with various sensors and electronic modules of
Gravity
Series,
plug and play, no soldering required. It not only helps you avoid the complex wiring , welding and
other operations, but also helps you quickly complete wiring and get started with the sensors or
electronic modules, to build prototypes faster.
This expansion shield is equipped with an external power supply port and a 3.3V/VIN power switch,
which makes the expansion shield able to drive high current components such as motors and
servos. There are 12 sets of digital ports, 8 sets of analog ports, 1 set of serial port and 2 sets of I2C
ports on the expansion shield. Various modules can be easily connected to it. Additional, there is an
onboard 3.3V LDO, which meets the power demand of multiple modules at the same time. What's
more, the RST button and the USR button are all on the shield, which is easy to reset or restore the
motherboard.
