- 100% Brand New and High Quality;
- 2012 New Version Arduino UNO R3 Development Board;
- With more stable RESET circuit.
- An easy-to-use type open source controller.
New Version Board Advantage: Arduino UNO R3 is an easy-to-use type open supply controller which was newly introduced in 2012. Specification: * Operating Voltage : 5V * Input Voltage (recommended) : 7-12V * Input Voltage (Limits) : 6-20V * Digital I/O Pins: 14 (of which 6 offer you PWM output) * Analog Input Pins: 6 * DC Current per I/O Pin : 40 Ma * DC Current for 3. More stable RESET circuit. In addition, add 2 pins alongside the RESET, a single is IOREF, which can make the expansion board adapt to board voltage. 5KB utilized by bootloader * SRAM: 2KB (ATmega328) * EEPROM: 1KB (ATmega328) * Clock Speed: 16MHz Package: 1pcs Arduino UNO R3 Development Board+1pcs USB Cable 2. The biggest difference lies in the element of USB converting to serial port circuit. This pin is always to tell expansion board the present onboard voltage (for example, when UNO is 5V, which could be noticed as a copy with the energy supply pin, does not give a level pull-up) ; the other is an occupy pin to grow to be utilized later. On the hardware, there is no big alter compared with Arduino UNO. This does not mean that there is R3 with 16K flash let your code run fast, this update is for USB interface chip. In theory, it let UNO can simulate USB HID such as MIDI/Joystick/Keyboard. The position of RESET key was also changed, moved to board corner near the USB interface, which is more convenient to press. 3V Pin : 150m A * Flash Memory: 32KB (ATmega328) of which 0. The computer software is going to be the identical as before, no big change. 3. 8U2 was replaced by ATmega16U2. Pin Change: Two I2C pins are added on the side of pin AREF (SDA and SCL, just the copy of Analog 4and 5, not an additional I2C interface ). Function: 1. The replacement is ATMega16U2 chip, so the expense may enhance a little.
