Gravity: IO Expansion & Motor Driver Shield - an expansion board for Arduino

Base Shield V2 is an extension for tiles with an Arduino shield connector, it has a Grove connector, which can be connected to Grove-compatible modules / sensors. Seeedstudio 103030000

This shield allows you to interface Wixel wireless modules to your Arduino (and other compatible products), enabling simple wireless programming, debugging, and control using standard Arduino software. Pololu 2513

The CAN-BUS Arduino Shield v2.0 can be stacked on an Arduino UNO, Arduino Leonardo or Arduino MEGA board. The shield integrates an MCP2515 CAN-BUS chip on the shield and has a CAN-BUS transceiver function. With an on-board DB9 and CAN-BUS connector you can choose a suitable port according to your host device. There is also an integrated MicroSD socket for data storage. DFR0370

GPS expansion module with 72-channel GNSS receiver SAM-M8Q dedicated to Arduino. The chip can receive data from all major positioning systems: GPS, GLONASS and Galileo. It has derived UART and I2C interfaces. Arduino ASX00017

This LC8822-2020 module with eight addressable RGB LEDs allows you to create lighting effects, animations, and visual signals in electronics projects. Thanks to I2C/Qwiic communication and an STM32C011 microcontroller, integration with the Arduino UNO R4 WiFi or Nano is quick and easy, and the I2C address can be easily changed programmatically. The module is fully compatible with the Arduino Cloud and the Modulino library, allowing you to launch your first effects in minutes. Arduino ABX00109
