The official Arduino Uno R3 DIP Edition and official Arduino Uno R3 SMD Edition are also available.Arduino uno Datasheets Context Search Catalog DatasheetĪbstract: arduino uno r3 atmega 328 arduino 328 arduino uno pin aref Atmel microcontroller in arduino uno of arduino uno These seemingly insignificant improvements have made the Arduino-compatible Uno R3 ATmega328P?s drivers and hardware much easier and simpler to utilize, making it an obvious upgrade from the original versions.
These include the addition of solder pads from pins PB4 through PB7 to the USB header, ICSP header pins rather than simple solder pads, and a 10-pin connector for the I2C, AD4/SDA and AD5/SCL. In terms of upgrades since previous versions of the Arduino UNO, the Arduino UNO R3 CH340 not only offers a variety of major upgrades that improve the power and efficiency of the board, but also a few minor quality-of-life upgrades.
It not only makes prototyping and development more accessible to students and hobbyists, but it also encourages the open-source Maker movement.
The Uno R3 ATmega328P?s drivers for the chip are available for either Windows or MacOS, depending on the operating system that you use. The Arduino UNO R3 CH340 is a clone of the standard UNO R3, but has been modified to bypass the standard (and expensive) FTDI drivers with the CH340 USB serial chip. Flash Memory: 32 KB (ATmega328) of which 0.5 KB used by bootloader.Digital I/O Pins: 14 (of which 6 provide PWM output).
