Expansion modules — I/O expanders, communication modules and breakout boards.
Expansion modules add new functions to development boards and microcontrollers, such as Wi-Fi, Bluetooth, GPS, LoRa, displays, audio, motor control and data storage. They save time compared to designing circuits from scratch and are ideal for prototyping and learning. Most modules connect through common interfaces such as I2C, SPI, UART or GPIO, which makes them compatible with Arduino, Raspberry Pi, ESP32 and other boards. Check the voltage level (3.3 V or 5 V), interface and pin layout before ordering. Libraries and code examples for popular modules are widely available online.
