Extend an I2C connection using differential signaling with this QwiicBus EndPoint. The PCA9615 converts the ordinary bus signals for transport over standard Ethernet cable without requiring a different application data protocol. EndPoint boards form the ends of the connection, and optional MidPoint boards can add sensor branches along the route.

Before you buy
