The Explore Ultra PIC Kit comes with all the things required, not just for this experiment but for the entire series. And even if you think of migrating to PIC or Arduino, you'll have breakout boards that fit on to this, hence we believe it is a great investment for learning hands on Embedded Systems. The kit is fully open source, you may use the schematics, the design files and all of the source code and build something cool on your own. And when you do that do not forget to share with us what you've done. We would be happy to see you building something cool.

The latest version of Ultra PIC dev kit is modular in both hardware and software. The kit comprises of the Ultra One Base Board and PIC breakout board as the main components.

The PIC breakout board comes with 16F877A, however you may use any other 40 pin PIC MCUs like the 18F4550. The 16F877A comes with a UART bootloader hence no external programmer is required.

The Ultra One baseboard can additionally be used with several AVR, 8051 and Arduino Microcontrollers, we beleive this kit to is a solid gate way to Embedded Systems. This is not it, even the USB to Serial Convertor on board is moduler, you can take it off and use it any of the other projects. The base board is fully open, no peripheral is directly connected to the MCU breakout board. You may connect any peripheral to any port/pin you wish.

The newer version also supports 128x64 Graphics display as well as 128x64 OLED display. The story of the Ultra Kit does not end here, we have even made the code libraries for all major 8 bit microcontrollers modular. It means you can simple upgrade or even switch your project to a different microcontroller/architecture without changing your application code. The kit ships with all the additional stuff mentioned below to get you started; kickstart you're embedded development. What are you waiting for?

Driver Installation

Software Setup

Complete Board Test

The board is shipped with test software loaded in the controller. Connect the board to the System, Open the Serial Terminal and reset the Controller. Follow the below procedure to test all the peripherals.


Connect the LED's, Buzzer and Relays to any of the port pins and observe the Led Blink, Buzzer-Beep and Relay-Chattering . *Note:The Rx,Tx pins will not blink as they are controlled by CP2102(Usb2Serial). PIC GPIO Testing.png
