The most generous WRTnode by far 
- 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
- Directly in the OpenWrt to simulate the acquisition, providing more than 14 native PWM, providing nearly 50 GPIO
- Provide Arduino compatible with API in Linux, and provide the script (node.js\python, etc.) environment call them, lower hardware development threshold
- MCU real-time control, which can realize the precise millisecond level response delay control, MCU using RT-THREAD real-time system
