The Explore Ultra 8051 Kit comes with all the things required, not just for this experiment but for the entire series. 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 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 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 your embedded development. What are you waiting for?

Supported Controllers

Controller Flashing Software External Programmer Comments
At89s52 XploreFlash/ProgIsp UsbAsp Programmer IC is cheap and easily available but needs external programmer
P89v519d2 Flash Magic Not required, uses on board USB NXP has stopped manufacturing the IC and only the stock items are being sold.
SST8951RD2 Easy ISP Not required, uses on board USB IC is good but the programming software is not stable, doesn't save the configuration, needs manual reset and many other problems.
w78e052d Nuvoton ISP Not required, uses on board USB IC is cheap and good GUI for flasing the code. FLashing hex file takes less time compared to all

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.

GPIO Test

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). GpioTest.png
