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.
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.
XT60 to Banana Cable
This XT60 to Banana Cable is often used in different battery management systems. The shape of this generic XT60 prevents reverse polarity, and when plugged in the connection is super-solid. Perfect for applications up to 65A continuous draw.
XT60 Connector Set
These connectors are made from high-temp nylon with gold-plated spring pins or sockets molded in. The shape of this generic XT60 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.
ECC81 Pre-Amp Vacuum Tube
ECC81 is 12AT7 medium gain pre-amplifying double triode. Can be also used as replacement for 12AX7 in many applications. Very smooth and warm sound. Very low microphonic. Good for phase inverters or reverb drivers.
Featured Products
CAN-BUS Shield
The CAN-BUS Shield provides your Arduino or Redboard with CAN-BUS capabilities and allows you to hack your vehicle. This shield allows you to poll the ECU for information including coolant temperature, throttle position, vehicle speed, and engine rpms. You can also store this data or output it to a screen to make an in-dash project.
4 Pin Low Profile Connector Set
The low profile header set is great for making your own PCB wire connections. This is a low profile header set, which includes a wire housing, pcb socket, as well as the crimpable pins. The pitch spacing for the socket is 2.54mm.
T8 Lead Screw – 300mm
This is a T8 300mm lead screw and brass flange nut set which can be self-locking. The T8 lead screw is perfect for high torque requirements of transmission, such as the aixs for 3D printer. The lead screw also can carry larger load than the threaded rod.
DS1307 Real Time Clock Module
This real time clock module is based on the DS1307 chip which supports the I2C protocol. The clock and calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either a 24-hour or 12-hour format with AM/PM indicator.
Note: CR2032 Coin Cell Batteryis not included.
Trinket – 3.3V 8MHz
Trinket may be small, but do not be fooled by its size! It’s a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power. We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. Perfect for when you don’t want to give up your expensive dev-board and you aren’t willing to take apart the project you worked so hard to design. It’s our lowest-cost arduino-IDE programmable board!
Make: More Electronic
Electronics is much more than resistors, capacitors, transistors, and diodes. There is a world of projects you can create by using comparators, op-amps, and sensors. And don t overlook the brainpower of logic chips! This sequel to the best-selling Make: Electronic offers 36 new step-by-step experiments to teach you how to add computational power to your projects.
EL Wire – Purple
EL Wire, also known as electroluminescent wire is a thin phosphor coated wire in a tube which lights up when 120VAC is applied to it. EL Wires give off a neon type of glow which looks amazing in any environments! EL Wires are also extremely flexible, where it can be shaped to your liking. This EL Wire has a length of 2M.
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!
PN532 RFID/NFC Shield
The PN532 NFC Shield works with the 13.56MHz frequency. This shield allows you to read and write any 13.56MHz tags with the Arduino. You can also communicate with any smartphone with the P2P (peer-to-peer) protocol.
