The Chameleon uses an Atmel AVR ATMega 328P as the main master processor (client) and Parallax multicore Propeller chip, includes the Arduino bootloader too –
The Chameleon(TM) AVR 8-Bit is the evolution of the high performance, small footprint, application development board. Similar to the BASIC Stamp(TM) and Arduino(TM) in concept, the Chameleon takes these products to the next level with a huge leap in computational performance as well as I/O interfaces. Simply put, the Chameleon is a credit card sized computer with (2) processors, (9) processing cores, 1 MByte of on board FLASH, 64K of EEPROM, and over 170 MIPS of processing power! If that wasn’t enough, the numerous I/O interfaces include composite video for NTSC/PAL generation, VGA, audio out, PS/2 for keyboards and mice. Additionally, the Chameleon has a number of digital I/Os and Analog inputs making the Chameleon perfect for industrial controllers, experimentation, education, wearable computing, or hobbyist use.
