8051 Development Board Setup
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?

|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, Set the baud rate to 9600 and reset the Controller. Below Test menu will appear, Select the required peripheral and 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).
