Have you tried to develop microcontroller applications, but been frustrated by complicated assembly language programming? Or have you run into limitations found in simple Basic language compilers? Why not step up to C and the power of the Arduino development environment and libraries? The new APP-IV is designed from the ground up to run C programs. And not some minimalist toy version of C, but the open source GNU C compiler used by the Aruino -- a powerful optimizing compiler that is used to build programs as complex as the Linux operating system.

All programming is done from a standard serial port on your computer using your choice of Arduino, AVR Prog, UISP, or AVRDude software.

There's no easier way to start programming microcontrollers in C. If you prefer to use assembler, no problem! Not only can you mix assembly language with your C programs, but the board will work fine with Atmel's AVR Studio and the companion AVR Prog programming software.

The APP-IVa is based on our popular GPMPU40 board -- you can use the edge connector to interface to external circuitry or use the supplied pins to plug the board directly into a solderless breadboard. This makes prototyping simple. All you need is a 9V battery (or other suitable power supply) and a standard serial cable or USB adapter. There's even room onboard for an extra 8 pin IC, perfect for an op-amp or other small circuitry you need to add.

Look at the powerful capabilities of this board:

Atmel AVR ATmega328 processor running at 16MHz
Real time counter, 1 16-bit timer/counter, and 2 8-bit timer/counters
6 PWM channels
UART, I2C, and SPI interfaces
Hardware multiplier
Analog comparator
6 channels of 10-bit A/D and 2 channels of 8-bit A/D
32K bytes of flash memory (some used by Arduino loader)
2K of RAM
1K bytes of EEPROM
Fully Arduino-compatible (software).

Please note that this is a kit and does require soldering and basic electronic tools. This allows you to customize the board to fit your needs. All the parts are through hole, and the solder masked board is very easy to assemble.
