Development Board 16 Analog Input Pins for R3 with Data Cable 5V

Feature: 1. Replace the 2011 version with the high performance chip. The ISP FLASH capacity is doubled for more powerful function expansion and development needs. 2. In addition to the traditional USB to serial port function, allows users to program other functions, such as mouse, keyboard, joystick, camera, etc. 3. The external interface adds SDA and SCL (located on the left side of AREF) based on the 2011 version. 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. 5. The RESET circuit is improved over the 2011 version. To prevent accidental reset of RESET, the RESET circuit is more stable.
