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). Goes great with our 1m K-type thermocouple.
New! Now uses the MAX31855K instead of the MAX6675, so it can measure a wider temperature measurement range. Please note! the MAX31855 is not pin compatible or drop-in code compatible with the MAX6675. We do have an Arduino library for both chips but you'll need to adjust any existing MAX6675 designs for the new MAX31855. The MAX6675 has been discontinued by Maxim.
Version 2.0 now includes ferrite beads and filter capacitor onboard for better stability
This is a row of 40 break away headers spaced 0.1" apart with long pins on both sides. This header is especially useful when you need to connect a PCB to a solderless breadboard. Each header can be broken apart to your preference to fit custom PCBs or general custom headers.
LEDs - those blinky things. A must have for power indication, pin status, opto-electronic sensors, and fun blinky displays.
This is a very basic 5mm LED with a green lens. It has a typical forward voltage of 2.0V and a rated forward current of 20mA.
The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). EasyDriver requires a 7V to 30V supply to power the motor and can power any voltage of stepper motor. The EasyDriver has an on board voltage regulator for the digital...
This is high-precision BMP180 low-power digital barometer breakout board. The BMP180 offers a pressure measuring range of 300 to 1100 hPa with an accuracy down to 0.02 hPa in advanced resolution mode. it\'s based on piezo-resistive technology for high accuracy, ruggedness and long term stability. These come factory-calibrated, with the calibration...
Stepper motors are great motors for position control. They can be found in desktop printers, plotters, 3d printers, CNC milling machines, and anything else requiring precise position control. Steppers are a special segment of brushless motors. They are purposely built for high-holding torque. This high-holding torque gives the user the ability to...
This is a cute half size breadboard which has 400 tie-points, is great for small projects. it\'s 2.2" x 3.4" (5.5cm x 8.2cm) with a standard double-strip (300pts) in the middle and two power rails (100pts) on both sides. You can pull the power rails off easily to make the breadboard as thin as 1.4" (3.5cm) and stick it onto your Raspberry Pi. You...
Miniature Single Pull Single Throw switches. These are high quality Omron type B3F momentary on switches. This switch has a very large 5mm tall button. Perfect as an embedded switch behind an enclosure wall. Rated up to 50mA.
This \'full-size\' breadboard with 830 tie points is perfect for small and medium projects. it\'s 2.2" x 7" (5.4cm x 16.5cm) with a standard double-strip (630pts) in the middle and two power rails (200pts) on both sides. You can pull the power rails off easily to make the breadboard as thin as 1.4" (3.5cm). You can also "snap" these breadboards...
The Big Easy Driver, designed by Brian Schmalz, is a stepper motor driver board for bi-polar stepper motors up to 2A/phase. It is based on the Allegro A4988 stepper driver chip. it\'s the next version of the popular Easy Driver board.
This is the basic L7805 voltage regulator, a three-terminal positive regulator with a 5V fixed output voltage. This fixed regulator provides a local regulation, internal current limiting, thermal shut-down control, and safe area protection for your project. Each one of these voltage regulators can output a max current of 1.5A.
The Pi T-Cobbler breaks out all 40 pins from the 40 pin GPIO header onto a solderless breadboard. This mini kit will make prototyping with the Raspberry Pi super easy. Each broken out pin is labeled for easy identification without looking at cheat sheets.
