Core+, 644pa (DIY)
Microduino-Core+ is an 8-bit microcontroller development core board based on Atmel ATmega1284P and ATmega644PA series as the core and it is an open-source controller module compatible with Arduino UNO. Beside Microduino-core+ has the features of Microduino-Core, the number of input and output of Flash, RAM, EEPROM of it has been greatly improved, and the pin conforms to the norms of Microduino, and the players can upgrade core to core+ smoothly, without modifying the arduino code basically.
Microduino uses java and C language development environment, same to Arduino. Players can use Arduino IDE, cooperated with software such as Flash or Processing , with Microduino and other electronic components, modules and sensors to make many funny interactive works.
