Logic Level Converter Bi-Directional IIC 4 Way Level Conversion Module Description: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...

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: SF-BOB-11189 | Brand: SparkFun

The ‘must have’ IC for TTL/CMOS projects finally has its own breakout board! This is the RS232 converter IC that is capable of running at 3V and communicating with 5V logic.We’ve taken the SOIC package MAX3232 and bro...

SKU: AF-935 | Brand: Adafruit

The MCP4725 breakout board provides a 12-bit digital-to-analogue converter (DAC) over I2C. Send a digital value and the VOUT pin outputs the corresponding analogue voltage — ideal for generating waveforms, adjustable ...

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-COM-08636 | Brand: SparkFun

The MCP3002 is a 10-bit analog-to-digital converter (ADC) with a simple SPI interface, available in a breadboard-friendly 8-pin DIP package. Use it to add analog input capability to microcontrollers that lack an ADC, ...

SKU: AF-1083 | Brand: Adafruit

Add high-speed analog-to-digital conversion to any microcontroller with the ADS1015 breakout. This 12-bit ADC delivers 3,300 samples per second over I2C, with four single-ended or two differential input channels and a...

SKU: DF-DFR0077 | Brand: DFRobot

This converter uses MAX202-based level shifter for converting TTL (Transistor-Transistor Logic) -level serial to standard RS232 serial.RS232 is widely used in radio modifications,phone flash, XBOX360 flash, GPS, vehic...

SKU: SF-BOB-13906 | Brand: SparkFun

The SparkFun Multiplexer Breakout provides access to all pins and features of the 74HC4051, an 8-channel analog multiplexer/demultiplexer. The 74HC4051 allows you to turn four I/O pins into eight multifunctional, indi...

SKU: AF-2946 | Brand: Adafruit

The Adafruit IS31FL3731 breakout is a charlieplexed PWM LED matrix driver that controls a 16×9 grid of individually dimmable LEDs over I2C. Each of the 144 LEDs can be set to any brightness level with 8-bit (256-level...

SKU: SF-COM-15099 | Brand: SparkFun

Add another eight pins to your microcontroller using a MCP23008 port expander. The MCP23008 uses two I2C pins which can be shared with other I2C devices, and in exchange gives you eight general purpose pins. You can s...

SKU: PI-COM0205 | Brand: Pimoroni

The MCP3008 is a 10-bit analogue-to-digital converter with eight single-ended input channels, communicating via SPI. It's a popular choice for adding analogue inputs to the Raspberry Pi and other digital-only boards —...
