Level Translator Breakout – PCA9306 I2C電平轉換模組

每個工程師和業餘愛好者都應該在他們的桌面上有幾個必備的板，雙向電壓電平轉換器突破就是其中之一！由於不同的部件有時會使用不同的電壓電平進行通信，因此電壓電平轉換器可以使不同部件發揮良好性能的關鍵。

PCA9306是一款雙向I2C總線和SMBus電壓電平轉換器，工作在1.2V至3.3V的低端，1.8V至5.5V的高端。只需將低端和高端參考電壓分別應用於VREF1和VREF2，連接I / O並將Enable引腳驅動為高電平，以便在不使用方向引腳的情況下打開雙向電壓轉換！

SparkFun Level Translator Breakout – PCA9306

There are a couple must-have boards that every engineer and hobbyist should have on their desk, and this PCA9306 dual, bidirectional voltage-level translator breakout is one of them! Because different parts sometimes use different voltage levels to communicate, voltage level translators can be the key to making different parts play nice.

The PCA9306 is a dual bidirectional I²C-bus and SMBus voltage-level translator that’s operational on the low side from 1.2V to 3.3V and on the high side from 1.8V to 5.5V. Simply apply your low and high-side reference voltages to the VREF1 and VREF2 respectively, connect your I/O and drive the Enable pin high to open bidirectional voltage translation without the use of a direction pin!

We’ve updated this classic board to use a new footprint as well as adding a second ground pin and breaking out the enable pin.
