The SparkFun 8 Channel Level Shifter Breakout features the TXS01018E™ 8-bit, bi-directional logic level translator from Texas Instruments. This board allows you to easily shift logic between devices running at different common microcontroller voltages such as 1.8V, 3.3V and 5V. The TXS0108E can transmit data between ports at max speeds of 110Mbps (push/pull) or 1.2Mbps (open drain) so you can use a 3.3V SPI device with a 5V microcontroller like the SparkFun RedBoard Plus without sacrificing...

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...

If you've ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The SparkFun bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. This level converter also works with 2.8V and 1.8V devices. What really separates this Logic level converter from our previous versions is that you can successfully set your high and low voltages and step up and down between them safely on the...

This is a board designed for opto-isolation. This board is helpful for connecting digital systems (like a 5V microcontroller) to a high-voltage or noisy system. This board electrically isolates a controller from the high-power system by use of an opto-isolator IC. This IC has two LEDs and two photodiodes built-in. This allows the low-voltage side to control a high voltage side. We often use this board to allow a microcontroller control servos or other motors that use a higher voltage than the...

This is a breakout board for the Texas Instruments TXB0104 module. The TXB0104 is a 4-bit bidirectional voltage-level translator with automatic direction sensing. This 4-bit noninverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2V to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65V to 5.5V. This allows for universal low-voltage bidirectional translation...
