SKU: SF-BOB-12009 | Brand: SparkFun

The SparkFun Bi-Directional Logic Level Converter safely translates signals between different voltage levels — stepping 5V down to 3.3V and 3.3V up to 5V on the same channel. It also works with 2.8V and 1.8V devices, ...

SKU: DF-DFR0626 | Brand: DFRobot

This is an IO expansion module that based on the chip MCP23017. The module can expand additional 16 IOs. It can set 8 IIC addresses, which means with this module, the microcontroller can connect 8 modules, and expand ...

SKU: SF-BOB-09056 | Brand: SparkFun

A breakout board for the CD74HC4067 16-channel analogue/digital multiplexer/demultiplexer. This IC internally routes a common signal pin (SIG) to one of 16 channel pins, working with both analogue and digital signals ...

SKU: AF-1875 | Brand: Adafruit

Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers find that they need to perform level shifting/conversion to protect the 3.3V de...

SKU: SF-BOB-09118 | Brand: SparkFun

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 h...
