This development board is based on the common Arduino Uno R3 reference design. It is identical in specification other than it makes use of the ubiquitous CH340 USB interface IC to reduce production cost and therefore allow this board to be sold at a fraction of the cost of the standard Uno without sacrificing any of the Unos functionality. It will run any sketch designed of an Arduino Uno without requiring any modification.
Additionally, this Uno development board also includes the option of being able to add additional pins for the standard Arduino headers, I2C and power pins.
Specification
Product code: HCARDU0119 Microcontroller: ATMega328p (QFP) Operating voltage: 5V (via USB or 5V header) or 7 to 12V via 2.1mm DC socket Digital IO: 1 4 (of which 6 provide PWM) Analogue inputs: 6 (10 bit) Digital pin current: 40mA source/sink (100mA max per port) 3.3V DC current: 50mA Flash memory: 32KB (of which 0.5KB used by bootloader) SRAM: 2KB EEPROM: 1KB Clock speed: 16MHz
USB Drivers
Most modern operating systems (Windows/OSX/Linux) will support the CH340 via their automatic driver install process so in most cases adding driver support for this development board should be a simple case of plugging the board into your computer. However, if your OS does not automatically install a driver the appropriate driver can be downloaded from below:
Windows Installation Instructions
Drivers are available in the link below. Simply download and unzip them, plug in your Uno+ and when the new hardware is detected, point the wizard to the folder you just unzipped to and it should install without any problems.
