This Bi-Directional Logic Level Converter is a breadboard-friendly device that converts between 5V and 3.3V logic.

When you need to switch a lot of power, N channel MOSFETs are best for the job.

This tiny logic level shifter features four bi-directional channels, allowing for safe and easy communication between devices operating at different logic levels. It can convert signals as low as 1.5 V to as high as 18 V and vice versa, and its four channels are enough to support most common bidirectional and unidirectional digital interfaces, including I²C, SPI, and asynchronous TTL serial.

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...

A common and insanely versatile timer/oscillator from TI - blink an LED, generate tones, triggers and thousands of other uses.

Add lots more outputs to a microcontroller system with chainable shift registers. These chips take a serial input (SPI) of 1 byte (8 bits) and then output those...

We've been stocking WS2811-n-friends for a long time, enough to see many iterations and versions of the "one-wire-control" addressable LED...

This 12V to 3.3V level converter module with 4-channel photoelectric isolation features common anode / common cathode / differential signal inputs. The...

Sometimes you feel low, and sometimes you feel high - cause your logic levels are opposite what they should be! But this easy-to-use inverter chip will flip that...

This is a breakout board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067. This chip is like a rotary switch - it internally routes the common pin (COM in the schematic, SIG on the board) to one of 16 channel pins (CHANxx). It works with both digital and analog signals (the voltage can’t be higher than VCC), and the connections function in either direction. To control it, connect 4 digital outputs to the chip’s address select pins (S0-S3), and send it the binary address of the channel you want (see the datasheet for details). This allows you to connect up to 16 sensors to your system using only 5 pins!

This USB to TTL converter combine the USB-232-1 (USB to Single RS232 Adapter) and TTL-232-1 (Port-powered RS232/TTL converter) allows you to convert USB to TTL/CMOS compatible levels and vice versa.

ULN2003N 16 Pin Darlington transistor array

This is a breakout for the SOIC version of the 74HC595 shift register IC. Clock in data and latch it to free up IO pins on your micro. All pins from the IC are broken out to standard 0.1" spaced headers. The Serial in and out pins are on opposite sides of the board with the remaining pins carried over so that multiple shift register boards can be chained together.

This adapter helps to connect TTL (Transistor-Transistor Logic) level signals to RS232 interface.

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.

The NAND module is a logic gate with two inputs. Think of it as “not and.” The NAND module will always send an on signal unless both input one and input two are receiving an on signal. It’s the exact opposite of the AND module.

This is a USB to TTL Serial Cable which allows for a simple way to connect TTL interface devices to USB. The I/O pins of this cable are configured to operate at 3.3V specifically with a Raspberry Pi with each serial pin broken apart. Thanks to its separated pins, this cable is a perfect candidate for powering, connecting, and accessing the login and debug console on the Raspberry Pi.
