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 you're 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 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).

RTC Test
The DS1307 RTC module will be connected I2C(SCL-RC.3,SDA-RC.4) pins as shown in below image.
EEprom Test
(A-Z) is wriiten to eeprom and then read it back. Same is transmitted on UART.
Adc Test
Ultra Board has a Pot, LDR and a temperature sensor. ADC values from these sensors is read and transmtted on UART. Below table shows the sensor pin connection.
| Sensor | Adc Channel | Port Pin |
|---|---|---|
| Temperature | AN0 | RA0 |
| POT | AN1 | RA1 |
| LDR | AN2 | RA2 |
Keypad Test
