  • Arduino Mega/ Uno R3 Prototyping Prototype Shield with Mini Expansion Breadboard TechMakers


    This prototyping shield is the best out there, and now is even better with Version R3 – updated for the most compatibility with just about all the Arduinos! It works with UNO, Mega, Leonardo, NG, Diecimila, Duemilanove, and compatible Arduino. Yun’s and Arduino Ethernets have a chunky Ethernet jack that gets in the way of stacking, you can use the stacking headers included and it will work, just doesn’t sit nice and flat.


    - Prototype Shield with a compatible layout for Arduino
    - Mini Breadboard with self-adhesive tape on the back, easy to stick on the Prototype Shield.
    - A surface-mount chip area on Breadboard  for up to 14 SOIC size parts
    - One IC pattern for adding DIP ICs up to 20 pins
    - It has a nice standard 0.1″x0.1″ prototyping grid with big pads
    - Reset button brought to top level
    - 2 general use LEDs, red and green, as well as 2 matching resistors
    - Every pin is brought out

    Expansion Board Sensor Shield V5.0 Servo  Arduino UNO R3 TechMakers

    Product details:

              The Arduino I/O Expansion Shield provides an easy way to connect sensors, servos and RS485 device to Arduino board. It expands Arduino’s Digital I/O and Analog Input Pins with Power and GND. It also provides separate PWM Pins which are compatible with standard servo connector. Another unique feature is that the I/O shield has a build-in RS485 converter which allows Arduino communicating with RS485 devices. The communication socket provides an extremely easy way to plug a wireless module such as APC220 RF module and DF-Bluetooth module. It has an individual power input for Servos. A servo power jumper allows user to select using external power or internal power to drive the Servos.



  • Sensor Shield V5.0 allows you to connect to various modules like sensors, servos, relays, buttons, potentiometers
  • Each functional module has buckled port with VCC, GND and Output, which has corresponding port on the Sensor Shield, connected with a plain 2.54mm dual-female cable you may start playing already
  • Buckled brick cables are like cement for bricks, make the connections easier, secure and more professional looking
  • Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language.
  • Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP)
  • The open-source IDE can be downloaded for free (currently for Mac OS X, Windows and Linux)
