Delivery of this article contains only the following connected graph, the data transfer directly to the Internet, without the disc
Over the years, AudioCodes SCM in support of the majority of users have made great progress. The number of customer suggestions, we launched a new SH51-MINI minimum system development board learning board.

SH51-MINI Development Board Introduction:
1, PCB board size: 115mm * 80mm, thickness 1.6mm
2, the learning board power supply: standard power outlet, USB power jack, two power supply, can choose a
3, reset the system: on-board reset circuit is stable and reliable
4, IO Port: All microcontroller pins all the leads, and indicates the significance of each pin
5, each IO port has a square light-emitting diode indicates the status of the IO ports
6, 4 a 1k * 8 IO port status light exclusion for current limiting resistor, making the system work smoothly.
7, each exclusion of public foot jumper on the VCC connection with, the customer may need to choose whether to enable status indicator, the benefits of doing so can reduce the total current single chip to enhance the driving capability of IO ports, from the letter No inteference, whether to enable light, own, and convenient and practical.
8, standard ISP interface for download atmel chip
9, the power switch, power indicator
10, standard RS232 interface to facilitate connection with the computer, you can download the STC microcontroller program
