WRTnode2R - Mini Openwrt Devboard

WRTnode2R - Mini Openwrt Devboard is a development board for solutions connected to the Internet of Things that are Arduino compatible.

WRTnode2R - Mini Openwrt Devboard, more information

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
