The Gravity I/O Expansion Shield for Pyboard connects your Pyboard v1.1 to the DFRobot Gravity sensor and module ecosystem with colour-coded plug-and-play connectors. No soldering is required — simply plug Gravity-compatible sensors and modules into the clearly labelled ports.

An onboard external power input and 3.3 V/VIN power switch allow the shield to drive higher-current components such as servos and motors through dedicated ports, while an onboard 3.3 V LDO powers the remaining ports and connected modules.

Key Features

• Gravity-Compatible Connectors – Colour-coded, plug-and-play interface for Gravity sensors and modules
