■ INTRODUCTION
BUONO UNO can be used to many applications, but not all application need USB communication, so we release the BUONO UNO LITE R3, it’s based on BUONO UNO R3 and canceled the USB to UART part, the UNO LITE have a 6Pin connector which can be connected to USB serial light adaptor for uploading firmware and communication, This will help user to reduce cost in the application.
■ FEATURES
l Inherits all of BUONO UNO R3 features
l Compatible to Arduino UNO/Duemilanove’s pin layout, screw hole and dimensions
l 3.3V or 5V operating voltage selectable
l More visible location of indicator LEDs
l Evolved with SMD components
l Digital I/O pins 14 (of which 6 provied PWM output)
l Flash memory 32KB or which 0.5KB used by bootloader
l SRAM 2KB
l EEPROM 1KB
l Clock speed 16MHz
l Micro USB connection make the cable can be mixed use with most digital products such as cell phone
l 5V DC/DC provide 95% efficiency
l 6V to 23V width rang input
l Provide max 1.8A for peripheral circuits
l LC Low pass filter for AVCC make ADC much stable
l Ground terminal make measurement easier

■ INTRODUCTION
BUONO USB2SERIAL fully compatible with Arduino USB2Serial Light, but more compact, It’s can be working with all Arduino main processor.
■ FEATURES
l Status lights include Power / RXD / TXD activity
l Easy to connect to the Arduino Ethernet / Mini / Mini Pro / LilyPad Simple / Fio , and all BUONO LITE serials
l USB cable directly solder to the PCBA , so it’s more stable
l Pin to Pin compatible with Arduiono USB2Serial Light
l Modify female connector to male, most female header will be poor connection after many times
