我也给大家看一个,功能令人赞叹
Most 40-pin Atmel AVR processors supported
ATmega16,32
ATmega163,323
ATmega644
many more...
Advanced I/O
Ethernet: 10Mb/s Ethernet using ENC28J60 controller
USB: Full-speed USB using FT232R USB interface
Memory Card: SD/MMC Flash memory card slot
General I/O
DB-9 RS-232 serial port (with TXD, RXD, CTS, RTS signals)
4-pin I2C header or terminal block
Character LCD header and LCD bias voltage (for HD44780-compatible displays)
10-pin Serial I/O header with I2C, UART, and SPI pins
10-pin ISP header for external programmer hardware (such as STK500 or AVRISP)
10-pin JTAG header for external programming/debug hardware (such as JTAG-ICE)
10-pin headers for all I/O ports (same as STK500)
I/O ports are protected against damage due to shorting and overvoltage
Power input and supplies
Supply power via DC jack or USB bus
High-efficiency 5V regulator accepts 6-18Vin (90% eff. typ.)
On-board 3.3V linear regulator for ethernet, USB, and flash card interfaces
Socketed CPU crystal
Four user-accessible pushbuttons and LEDs
