2RSHLD-0.jpg

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

Software

  • OpenWrt based on CC 15.05
    • The default network segment changed to 192.168.8.1
  • * add WWAN port of apcli0 for the default WiFi repeater mode, and additional WRTnode series wireless management tools: aps/vw/ia, to manage the wireless connection
  • * add and adopt the MTK original drive ralink-wifi, ralink-ralink-mt76x8 for OpenWrt CC
  • * add WRTnode2R devices (DTS and related configuration), update the SPI driver
  • * add flash-stm for online burning STM32 chip, spi-bridge for online controlling STM32 chip.
  • MCU using RT-Thread v2.1.0 beta
  • *Porting Maple to provide Arduino API (functions) compatibility
  • * provides bootloader for OpenWrt burnning the STM32 firmware
