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.

Ludas Dual Motor Wireless Protoshield – 1.2A
Ludas Dual Motor Wireless Protoshield – 1.2A
The Ludus Protoshield Wireless is an Arduino compatible shield designed to make connecting motors and sensors to your Arduino-based development board as fast and easy as possible. This wireless Ludus is incredibly handy for throwing together remote control rovers and small autonomous robots. Simply attach this shield to your Arduino, attach an XBee, and you will be up and running in no time. The SparkFun Ludus Protoshield Wireless was developed by our Education department to help teach any interested individual the dynamics of wireless motor control through the Arduino IDE and was lovingly named after their very own mascot.
10 Pin Polarized Wire Assembly
The polarized connectors are also referred to as Molex connectors. This polarized wire set comes with a polarized socket and a 20cm polarized wire with open ended wire leads. The polarized socket has pitch spacing of 2.54mm.
HC-05 Bluetooth Module
This Bluetooth is a Bluetooth V2.0+EDR 3Mbps modulation with complete 2.4GHz radio transceiver. This Bluetooth module features a single chip Bluetooth system with CMOS technology and with AFH (Adaptive Frequency Hopping). It can be configured to either Master, Slave or Loopback modes. This Bluetooth module can connect or be connected to any device supporting SPP protocol.
Full Size Breadboard – Transparent
This is your tried and true full size solderless breadboard! It has 2 power buses, 10 columns, and 63 rows – with a total of 830 tie in points. All pins are spaced by a standard 0.1″. The two sets of five columns are separated by 2 columns with a 0.4″ distance between the holes. The board accepts wire sizes in the range of 20-29AWG. This board also has a self-adhesive on the back. The boards also have interlocking parts, so you can hook as many together as you d like.
GP2Y0A02YK IR Proximity Sensor (20 to 150cm)
The GP2Y0A02YK Sharp distance sensor is a great way to add obstacle avoidance or motion sensing to your robot or any other project. With a detection range of 20cm to 150cm and an analog voltage indicating the distance, this sensor is very easy to use. The sensor uses a 3pin JST (PH) female connectors.
LED Tactile Push Button – Green
This is a simple LED-illuminated tactile button with a green cap. It s just like a basic tactile button, but it lights up green! 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.
0.8mm Carbide Square End Mill Bit
These end mill are slightly different than PCB drill bits. Drill bits can only cut in an axial direction, meaning in line with the axis of the bit – or up and down on the PCB. End mills can move in any direction so you can drill side to side, up and down, etc. The cutting part is made from tungsten carbide and are suitable for circuit board cutting and probably some other soft metals and other materials. Each endmill has a high hardness, wear resistance and strength and they’re also super sharp which helps when cutting thru PCBs.
Raspberry Pi 4 Model B (4GB)
The speed and performance of the new Raspberry Pi 4 is a step up from earlier models. Whether you’re editing documents, browsing the web with a bunch of tabs open, juggling spreadsheets or drafting a presentation, you’ll find the experience smooth and very recognisable but on a smaller, more energy-efficient and much more cost-effective machine.
Hobby Unipolar Stepper Motor
These small steppers are a great way to get things moving, especially when positioning and repeatability is a concern.
Note: This is a Unipolar stepper, meaning that if you are going to drive it with a bipolar stepper driver, you will only use 4 of the 6 leads.
VNH5019 Dual Motor Shield – 12A
VNH5019 Dual Motor Shield – 12A
This shield makes it easy to control two high-power DC motors with your Arduino or Arduino-compatible board. Its dual robust VNH5019 motor drivers operate from 5.5 to 24 V and can deliver a continuous 12 A (30 A peak) per motor, or a continuous 24 A (60 A peak) to a single motor connected to both channels. These great drivers also offer current-sense feedback and accept ultrasonic PWM frequencies for quieter operation. The Arduino pin mappings can all be customized if the defaults are not convenient, and the motor driver control lines are broken out along the left side of the shield for general-purpose use without an Arduino.
