The PICnDuino is a two-in-one, Inexpensive, Arduino and Amicus18 Compatible, Direct To USB Development Board.

Its available in 6 colurs: Black, White, Red, Blue, Green and Yellow. It includes free headers and a USB Pen Drive with all the files with a neat logo printed on it.

Main Features:

• Direct to USB interface - no special programmer or power supply required
• Atmega 328P microcontroller (compatible with Arduino)
• PIC18F25K20 microcontroller (compatible with Amicus18)
• Seven onboard LED's (four of which can be directly controlled with the microcontrollers)
• Two reset buttons (one for each microcontroller)
• Microcontroller select switch (both microcontrollers run simultaneously, however this switch selects which one has access to the USB port. You can even select between them on the fly without powering down, unplugging or resetting the PICnDuino).
• A combined total of 44 I/O pins providing standard digital pins, analog, SPI, I2C, PWM, Interrupts and USART.
• A combined total of 64KB of program memory (some memory space is taken up by the Arduino and Amicus18 bootloaders)

Specs:

• 50mm long x 25mm high x 2mm thick PCB allowing direct connection to USB ports, hubs and cables.
• Two microcontrollers (Atmega328 and PIC18F25K20 - see below for details)
• A combined total of 44 I/O pins including standard digital pins, PWM, ADC, I2C, SPI and external interrupts.
• 3.3V regulator
• FT232RL chip (allows the microcontrollers to communicate via USB)
• Seven LED's - One for power, two for transmit / receive indications and then two each for the Amicus18 and Arduino (which are programmable).
• 16Mhz Crystal Oscillator

Atmega328P Specs:

• Loaded with Arduino Bootloader
• 16Mhz clock
• 32KB of program memory
• 1KB EEPROM
• 2KB RAM
• 14 Digital I/O pins (6 can be used as PWM pins)
• 8 10-bit Analog input pins
• SPI Bus
• I2C Bus
• USART
• External Interrupts
• 6 PWM pins

PIC18F25K20 Specs:

• Loaded with the Amicus18 Bootloader
• 64Mhz clock (16Mhz crystal multiplied by 4 with PLL)
• 32KB of program memory
• 256Bytes EEPROM
• 1.5KB RAM
• 13 Digital I/O pins
• 9 10-bit Analog input pins
• SPI Bus
• I2C Bus
• USART
• External Interrupts

Each 1GB Credit Card sized USB Flash Drive will come with a PICnDuino logo printed on it and will contain:

• Instructional video showing you how to install the Arduino and Amicus18 software and how to install the PICnDuino driver
• Instructional video showing you how to load your first programs onto the device including LED blinkers, LED faders and USART communications - all of which don't require any extra hardware. Infact, these pieces of example code are already built into the Arduino and Amicus18 software!
• PICnDuino schematic and PCB design files
• Bill of materials
• Links to download the Arduino and Amicus18 software
• Links to useful sites and forums
