SparkFun QwiicBus – EndPoint IIC 延長距離的絕佳解決方案並降低噪音

SparkFun QwiicBus – EndPoint 是擴展 I 2 C 通信總線範圍的最快、最簡單的方法。分線器使用 NXP 的 PCA9615 IC,它將兩個默認的 I 2 C 信號轉換為四個差分信號,兩個用於 SCL,兩個用於 SDA。差分信號通過以太網電纜發送,該電纜通過板載 RJ-45 連接器連接到分線器。差分信號允許 I 2 C 信號達到最遠 100 英尺的距離。同時仍保持其信號完整性!為了讓您更輕鬆地獲得讀數,所有通信均僅通過 I 2進行C,利用我們方便的 Qwiic 系統,因此無需焊接即可將其連接到系統的其餘部分。但是,如果您更喜歡使用麵包板,我們仍然斷開了 0.1 英寸間距的引腳。

QwiicBus 端點的簡單性是其最大的吸引力之一。其他 I 2 C 通信方法需要將 I 2 C 通信打包成另一種協議,無論是 RS-485 還是 1-Wire。但是,PCA9615通過使用差分收發器來保持 I 2 C 協議。

此更新版本的差分 I 2 C 分線器增加了兩個 0.1″ 間距的引腳,連接到 RJ-45 連接器上未使用的一對電線,因此用戶可以輕鬆利用未使用的一對電線來滿足他們的需要。

無論您是需要在受電機噪聲困擾的自動駕駛汽車上擴展 I 2 C 傳感器的範圍,還是想在家中或辦公室創建龐大的傳感器網絡,QwiicBus 端點都是延長距離和降低噪聲敏感性的絕佳解決方案.

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 differential signals are sent over an Ethernet cable, which attaches to the breakout through the on-board RJ-45 connectors. The differential signaling allows the I2C signals to reach distances of up to 100ft. while still maintaining their signal integrity! To make it even easier to get your readings, all communication is enacted exclusively via I2C, utilizing our handy Qwiic system so no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1″-spaced pins in case you prefer to use a breadboard.

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.

This updated version of the Differential I2C Breakout adds two 0.1″ spaced pins connected to the unused pair of wires on the RJ-45 connectors so users can easily take advantage of the unused pair for whatever they would like.

Whether you need to extend the range of an I2C sensor on an autonomous vehicle plagued with noise from motors or want to create a vast sensor network in your home or office, the QwiicBus EndPoint is a great solution to extend distance and reduce noise susceptibility.
