Power Connection Power modules supplies power for the entire development board ENK805X, it provides
5VDC output for all functional modules to work. Power Interface shown in Figure.
The connection needs through the external input direct-current power supply, the input range in 6V~12V, to recommend 9V the voltage. Note: The interface to the center of the positive.

Serial port connection explanation As shows, black 3Pin part for serial port output connection position. The design idea is facilitates other modules the connection. The serial port may connect computer's serial port position.
DC motor drive connecting the output DC motor driver IC is the completion of a similar DIY robot movements and toy car motor drive motor drive. It can drive one or two motors running.
Please note: I do not recommend you use it to drive high-power DC motor, due to driver IC connected to the L7805, power the greater the power consumption may increase in L7805. Possibly will damage the power supply chip-L7805.

Relay control output Relay outputs can be isolated for high-voltage electrical switch control. The relay outputs has two cluster switches, a group is often open, a group is often closed. You may need to implement an external device according to the switch control.
Please note: Use the relay switch, try not to use high-voltage electrical equipment to do controlled experiments. In order to avoid electric shock accident.
External Control Interface the 6Pin jack, uses in the external signal the input. Such as the RF received signal. You can programmatically control the input or output. At the same time you can refer to ENK schematic to understand and learn.
You can contact me via e-mail way, tell me all the problems you encounter, I will try to help you. Be happy to help you.

ISP programming
ENK805X development board offers a standard ISP programming interface AT89S52 Chip, you can be very easy to use with the ISP to connect to the control of programmers.
You can through the website http://www.ienk.com/documents.php?type=3, download digital LED test code. File Name: ledclock.hex. Test ENK805X digital LED, the following is my own computer presentations.
