The MS14N lets you embed Linux into your MCU projects. It is a low-cost, open hardware Linux motherboard for micro-controllers. It runs on an open-source Linux system, has a USB host port, and offers full Ethernet and 802.11 b/g/n WiFi capabilities.
The goal of the MS14N is to solve the connectivity problem and greatly enhance microcontroller products such as the Arduino.
MS14 supports a generic OpenWrt Linux version or a modified OpenWrt version, such as Arduino Yun.
Applications for MS14N include remote control of robots, data logging, web applications for data presentation, mesh networking over WiFi, and many more.
Features
- OpenWrt Inside
OpenWrt is a reliable Linux distribution for embedded systems. It is open source, well-developed, and well-maintained. OpenWrt uses a package system, lots of powerful utilities, and software that are maintained in package form. Users can easily install, remove these packages to make a deeply customized system.
- Open Hardware Design
Developers can improve or innovate on the hardware and release a new /unique product based on the requirement.
- Low Power Consumption
Around 1 watt of power consumption in working mode.
- AP, Client, or Mesh mode WiFi
Can be configured in different WiFi modes for various applications.
AP mode: as what a normal WiFi router does, so other WiFi clients can connect to MS14N and share its internet connection.
Client mode: as what a normal PC does to connect to your existing WiFi router for internet connection.
Ad-Hoc for mesh network.
- Modular Design
The most complicated parts are built as a motherboard. Developers focus on the MCU daughter board design only. This helps to reduce the development time, cost, risk, and difficulty in releasing a new product to test/seize the market.
- Production Enclosure
MS14N has a Professional/Industrial enclosure that can be used directly for the market.
- Managed by Web GUI, SSH or Serial
Built-in Web server provides convenient to use/configure/upgrade/monitor or have full control by SSH/Serial.
- Various firmware upgrade methods
Firmware can be upgraded via serial port, SSH access, GUI interface for easy maintenance.
- Safe Mode
Robust software/hardware interface to reduce after-sales support cost.
- Remote upgrade AVR daughter board
Daughter board can be upgraded remotely to reduce the maintaining cost and provide central management/ deployment.
- Compatible with Arduino Yun software
Reuse all the source from Arduino Yun to speed up development.
