What’s DuinoThumb ?

DuinoThumb is an AVR development board but can work with Arduino IDE which is smaller than the standard (about the thumb) but it covers the working property of Standard Arduino well. DuinoThumb does not use the standard Arduino BootLoader (serial port) but USBaspBootloader (USB port) is used to allow AVR connect to the PC without using the Serial 232 cable. In the other hand, we use USB cable in downloading the data into Flash. By this way, developing of Arduino program on DuinoThumb is easy because it is not necessary to connect further lines. Just plug DuinoThumb into the PC and install the driver, and then it is ready for programming.

Moreover, DuinoThumb circuit and legs are well designed to be consistent with one of opensource project named V-USB that enables us to use DuinoThumb with other related USB works.

What’s V-USB?

V-USB is the Library that the open source uses in AVR microcontroller emulation to deal with protocol of a USB (low speed 1.1) especially for the popular model, ATMega8/88/168 however; it can be portable to other models such as ATTiny2313 etc. There are many people using this project as a fundament to expand work development by using just only one AVR as follows
- USB to Serial Converter
- USB Mouse, USB Keyboard (HID)
- USB BootLoader
- USB Sensors
- Etc.

Devices in DuinoThumb V2 series
DuinoThumb V2 use 8 bit AVR microcontroller kind and we choose AVR ATMega 168 as a fundament. The details of this series as follows
    - DuinoThumb V2 board
            o ATmega168 AVR
                            • Features
                                        • 16KByte Flash, SRAM 1KByte, EEProm 512 Byte
                                        • Digital GPIO 14 bit
                                        • Analog GPIO 10 bit
            o Port ISP - make the burning of program is easier
            o Voltage directly from USB (and then reduce the voltage to 3.3V) or use a jumper to connect with the voltage directly (not reduce the voltage)
            o Reset button
            o LED use in Hardware test
            o Crystal 12Mhz make the development can be applied with most of USB and Arduino project works
    - Acrylic Case  - Transparent and fine case, prevent electrical short, dust and make the body strong.
    - CD of manual - sample basic programs
