WRTnode2R - Mini Openwrt Devboard, ulteriori informazioni

Bigger RAM, bigger ROM: almost a destop Linux
Duo-core & Duo-OS, mixed-up the incalculable Linux development resources and the real-time application
Arduino in javascript or python or any script in Linux
Making robot, making physical interaction, all in one and all in smooth

RAM expansion 4 times to 256MB than WRTnode1

Rom expansion 2 times to 32MB than WRTnode1

Power consumption is reduced by 50% compared with WRTnode1

Smaller 30% than WRTnode1
