8051 AVR MCU Minimum System Development Board Microcontroller Programmer E-947 The IO port is all led out, the classic minimal 51 system, eliminating soldering problems Integrated ISP 10P download interface, AT89S52 microcontroller easy to download. Welding is a round hole outlet to easily replace the crystal oscillator (default is 11.0592 M) Support chip: STC89C52 STC12C5A60S2 STC11 / 10x series AT89S52 chip compatible with the chip pin A switch for an easy experience. Power input 2 ways: DC-005 socket (the support seat is 5.5 * 2.1) and a row pin (next to the power switch). Expand 3 channels of VCC and GND as shown in the headings of the pins in the figure. Port P0 with extraction resistance. Reset mode: power on reset and external button reset. -
The board has in built Programmer capable of programming both AVR & 8051 family ICs.A 40 pin ZIF socket is used as Target to hold the 8051 IC. Additional 40 pin ZIF socket with modified connection is provided to host AVR ICs.This additional ZIF socket should be placed over the on- board ZIF socket to use AVR ICs. -
