Replace the 2011 version with the high performance chip. The ISP FLASH capacity is doubled for more powerful function expansion and development needs.<br/>2. In addition to the traditional USB to serial port function, allows users to program other functions, such as mouse, keyboard, joystick, camera, etc.<br/>3. The external interface adds SDA and SCL (located on the left side of AREF) based on the 2011 version.<br/>4. The IOREF interface can provide a voltage reference to the Shield. And for future series product compatibility, consider leaving a port on the left side of IOREF.<br/>5. The RESET circuit is improved over the 2011 version. To prevent accidental reset of RESET, the RESET circuit is more stable.<p><br/></p><p><b>Specification:</b></p>Item Type: Development Board<br/>Working Voltage: 5V<br/>Input Voltage (Recommended): 7-12V<br/>Input Voltage (Limit Value): 6-20V<br/>Digital I/O Pins: 54 (15 of which provide PWM output)<br/>Analog Input Pin: 16<br/>DC Current Per I/O Pin: 40 MA<br/>3.3V Pin DC Current: 50 MA<br/>Flash: 256 KB, 8 KB Of which is used by the bootloader<br/>SRAM:8 KB<br/>eeprom:4kb<br/>Clock Speed: 16 MHz<br/><p><br/></p><p><b>Package List:</b></p>1 x Development Board<div>1 x Data Cable</div></div><br/><p><br/><br/><br/><br/><br/><br/><br/><br/></p></div></div></div>
