SparkFun QwiicBus EndPoint

• SparkFun QwiicBus EndPoint
• Uses the PCA9615 buffer IC
• I2C Supply voltage range: 2.3 – 5.5 V
• Differential Supply voltage range: 3 – 5.5 V
• Extends I2C bus: up to 100 feet
• Qwiic Connectors: 2

The SparkFun QwiicBus EndPoint is the fastest and easiest way to extend the range of your I2C communication bus. The breakout uses NXP’s PCA9615 IC, which converts the two default I2C signals into four differential signals, two for SCL and two for SDA.

The simplicity of the QwiicBus EndPoint is one of its biggest appeals. Other I2C communication methods require packetizing I2C communication into another protocol, be it RS-485 or 1-Wire. However, the PCA9615 keeps the I2C protocol by utilizing a differential transceiver.
