SKU: DF-DFR0063 | Brand: DFRobot

This is an 16x2 LCD display screen with with I2C interface. It is able to display 16x2 characters on 2 lines, white characters on blue background. Usually, Arduino LCD display projects will run out of pin resources...

SKU: DF-DFR0154 | Brand: DFRobot

A 20×4 character I2C LCD display module compatible with Arduino and other microcontrollers. It shows white characters on a blue backlit background, and the I2C interface means you only need two data pins (SDA and SCL)...

SKU: EC-CIN3232RT | Brand: Elecrow

This module can be used to convert the RS232 voltage of PC to TTL voltage that used by microcontroller. Directly plug the DB9 connector your PC then you can communicate with the microcontrollers using the Serial port....

SKU: AF-2831 | Brand: Adafruit

This Photo Transistor Light Sensor is a simple sensor that detects ambient light. It's kind of the opposite of an LED - when light hits the little chip inside, it induces current to flow from the long pin...

SKU: AF-400 | Brand: Adafruit

Breakaway header is like the duct tape of electronics, and this header is one better with extra long pins on both sides. This makes it great for connecting things together that have two sockets - especially sold...

SKU: AF-5938 | Brand: Adafruit

A breakaway strip of 36 press-fit male pin headers at standard 2.54mm (0.1") pitch. These headers can be attached to PCBs without soldering — press them firmly into place using pliers for a friction-fit connection tha...

SKU: AF-2890 | Brand: Adafruit

This is the FeatherWing Doubler - a prototyping add-on and more for all Feather boards. This is similar to our FeatherWing Proto except there are two! The magic of the Doubler comes when stacking a Feather ...

SKU: AF-1862 | Brand: Adafruit

A simple 2-pin connector soldered onto a breadboard-friendly breakout. This is compatible with the "JST PH 2-pin" connector. Mates perfectly with all our 1-cell LiPoly and LiIon batteries as well as our 6V coin ...

SKU: SF-COM-16473 | Brand: SparkFun

The classic 555 timer/oscillator IC from Texas Instruments — one of the most versatile and widely used integrated circuits in electronics. With just a few external resistors and capacitors, it can generate timing dela...

SKU: SF-COM-09117 | Brand: SparkFun

This is a 12-step rotary encoder with a nice ‘clicking’ feel. It’s breadboard friendly, and has a pretty handy select switch (by pushing in on the knob). The encoder is different from a potentiometer in that an enc...

SKU: AF-161 | Brand: Adafruit

CdS cells are little light sensors. As the squiggly face is exposed to more light, the resistance goes down. When its light, the resistance is about 5-10KΩ, when dark it goes up to 200KΩ. To use, connect one side o...

SKU: DF-FIT0720 | Brand: DFRobot

These patch test hooks provide a solderless way to make signal and low-current connections between boards, sensors, and modules. The hook clips grab onto pins, pads, and component legs — perfect for prototyping with c...

SKU: AF-2765 | Brand: Adafruit

The Mini 2-Axis Analog Thumbstick is a compact, self-centring joystick with a black rocker cap, similar in style to PSP joysticks. It provides smooth directional analogue input using two 10 kΩ potentiometers — one for...

SKU: AF-3296 | Brand: Adafruit

The Adafruit DS1307 Real Time Clock breakout keeps accurate time even when your microcontroller loses power or is reprogrammed. This battery-backed I2C RTC is one of the most widely used clock chips, making it a relia...

SKU: AF-4570 | Brand: Adafruit

The Adafruit DS1841 is an I2C-controlled logarithmic digital potentiometer from Maxim with a resistance range of 3.7 kΩ to 22 kΩ across 128 tap points. Unlike linear potentiometers, the DS1841's logarithmic response c...
