Gravity: I/O Expansion Shield - expansion module for the OpenMV Cam M7 camera

Description

Expansion module for the OpenMV Cam M7 camera. The board has connectors compatible with the Gravity standard, thanks to which the user can connect additional sensors and peripheral modules to the camera. The module is equipped with a microUSB port (only used to power the module, therefore it cannot be programmed/debugged) and a 3.3 V/VIN power switch, enabling the connection of servos or motors. In the event of using components that require higher power consumption (motor or servo), they should be powered from ports P7 - P9, connecting the external power supply and switch the power supply to VIN. Power supply of P7, P8, P9 ports can be selected as 3.3V or VIN by switch. The other ports are supplied with the voltage of 3.3 V. It has digital, analog, serial and I2C pins. In addition, the board has a built-in 3.3 V LDO stabilizer that provides power to the Gravity modules. The OpenMV board works with a voltage of 3.3 V, therefore the analog inputs do not support 5 V. All signal pins have a voltage of 3.3 V. The user manual and sample program codes are available on the Wiki website.
