2.5.7.2 Grove UART Interface (J5)

The J5 connector provides a UART interface, connecting to the UART2 port of the AM335x processor. This Grove port enables easy integration with serial communication modules operating at 3.3V logic levels.

Common Grove UART modules compatible with this interface include wireless communication modules for Bluetooth®, Wi-Fi, and Long Range (LoRa) connectivity; Global Positioning System (GPS) and Global Navigation Satellite System (GNSS) receivers for location-based applications; Radio Frequency Identification (RFID) readers for identification and access control; and specialized sensor modules that utilize serial interfaces. This connectivity option extends the capabilities of the board into numerous communication domains with minimal integration effort.
