20×4 Character LCD for RepRap Ramps 1.4
This 20×4 LCD board is used with the RAMPS 1.4 3D printer controller. You simply connect the LCD to the RAMPS board. This control unit has a built in SD card reader, rotary encoder as well as a 20×4 LCD display.
5V 10A Switching Power Supply
This is a high quality AC to DC switching power adapter which gives a clean regulated 5VDC output at up to 10A. These adapter works with both 110 and 240VAC input, allowing them to work in any country! The barrel plug attached to these wall adapters are center positive with 2.1mm diameter.
ESP8266 Grove WiFi Module
UART WiFi is a serial transceiver module featuring the ubiquitous ESP8266 IoT SoC. With integrated TCP/IP protocol stack, this module lets your microcontroller interact with WiFi networks with only a few lines of code. Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning you can send simple text commands to control the device. The SoC features integrated WEP, WPA/WPA2, TKIP, AES, and WAPI engines, can act as an access point with DHCP, can join existing WiFi networks and has configurable MAC and IP addresses.
MAX31855 Type K Thermocouple Amplifier
Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. The MAX31855K does everything for you, and can be easily interfaced with any microcontroller, even one without an analog input. This breakout board has the chip itself, a 3.3V regulator with 10uF bypass capacitors and level shifting circuitry, all assembled and tested. Comes with a 2 pin terminal block (for connecting to the thermocouple) and pin header (to plug into any breadboard or perfboard).
MMA7260 & LISY300 – 6 DOF Atomic IMU
The 6DOF Atomic is a stripped-down IMU, designed to give good performance. The unit can run as a hard-wired UART interface (0-3.3V, 115200bps), or optionally with an XBee RF module, and is powered from a single LiPo (Lithium Polymer) battery. The processor is an Atmel ATMega328 running at 10MHz with 6 dedicated 10-bit ADC channels reading the sensors. Source code for the 6DOF Atomic is freely available and compiles with the free AVR GCC compiler.
Type K Thermocouple
Thermocouples are best used for measuring temperatures that can go above 100 Degree C. This is a bare wires bead-probe which can measure air or surface temperatures. Most inexpensive thermocouples have a vinyl covering which can melt at around 200 Degree C, this one uses a fiberglass braid so it can be used in high temperature measurements such as heaters and ovens. There’s a small piece of heat shrink on the end to keep the fiberglass from fraying. If you’re using at >250 Degree C temperatures, simply remove it with a small blade.
EC3 Connector Set
These connectors are made from high-temp nylon with gold-plated spring pins or sockets molded in. The shape of this generic EC3 prevents reverse polarity, and when plugged in the connection is super-solid. Perfect for applications up to 65A continuous draw. Sold in pairs of 1 male and 1 female connector.
Featured Products
RTC Data Logging Shield
The RTC Data Logging Shield is an easy way to add storage to your Arduino project. It supports SD, SDHC, and MicroSD TF cards and with onboard real time clock. Use the onboard toggle switch to select betweem types of SD cards.
WS2812 RGB LED Matrix Shield
WS2812 RGB LED Matrix Shield
This WS2812 Pixel Matrix Shield is equipped with 40 WS2812 RGB LEDs arranged in a 5×8 matrix. The shield is powered by the 5V onboard Arduino supply. An external power source of 4 to 6V may be required if you are planning on lighting all the pixel at once at full power
PEL12S Illuminated Rotary Encoder – 100RPM
Rotary encoders are used similarly to potentiometers. They re different from potentiometers in that an encoder has full rotation without limits. This PEL12S series 12mm encoder is a 90 degree encoder which uses 24 pulse/rev with a rating of 100RPM.
LED Tactile Push Button – Red
This is a simple LED-illuminated tactile button with a red cap. It s just like a basic tactile button, but it lights up red! So now you can get visual feedback, or light up your project. These have a 12mm body and are rated for 50mA. They don t easily fit into a breadboard, but check below for a breakout board. We also have these in a a variety of colors, check below to see the others.
2.1mm DC Barrel In-Line Power Switch
2.1mm DC Barrel In-Line Power Switch
Add a power switch to any project simply by plugging this between the power supply. This is the most useful thing you never knew you needed! You’ll want to pick up a bunch for your electronic projects. Comes with a 5.5/2.1mm barrel jack on one end an a plug on the other. In between is an in-line switch that is rated for 125V and 2Amps (its normally used for lamps, we suppose). Since most people will be using it with no more than 12VDC, we think it can probably handle up to 5A at that voltage.
Magnetic Liquid Float Switch
This float switch is used to sense the level of liquid within a tank. The switch has a built in reed switch allowing it to be activated though a magnetic field. This switch is made from non-toxic PP plastic which can float on must liquid. The switch is rated for 36V 0.5A.
LilyPad Pixel Board
We know you love adding color to your e-textiles, adding the LilyPad Pixel Board to your project will only make it better. The pixel board is equipped with a WS2812B which is actually an RGB LED with a WS2811 built right into the LED! Several of these breakouts can be chained together to form a display or an addressable string.
12V RGB LED Strip Controller
This LED controller can be used for most 12V to 24V RGB LED strips to control the color, speed and mode of the LED strip. This controller requires an additional 12V power supply or battery pack to be hooked up inline of the LED strip.
12V Silicon Neon LED Strip – Red
This neon-like LED strip is super flexible and bendy, they feature a single-color non-addressable LED strip with a solid chunk of translucent silicone rubber as a diffuser. They look incredible, and super easy to use and are a great way to make your projects light up!
