FTDI kontroler ALLNET MSC-06656

ALLNET 4duino_Yun_Shield is a Yun-compatible shield that brings OpenWrt-based networking and additional storage to Arduino boards. It runs the Open Source OpenWrt system (the same distribution used by Arduino Yun) and is compatible with Arduino IDE 1.5.4 and later. The shield provides LAN, Wi‑Fi and 3G dongle support, plus USB flash storage, allowing Arduino projects to access network services and extended storage while working with boards such as Uno, Duemilanove, Leonardo and Mega.

Advantages

The Yun Shield integrates a low-power Linux environment with Arduino compatibility, offering multiple internet connection options, software-upgradeable firmware and management via web GUI or SSH. An external antenna improves wireless stability, and the shield can be powered from the Arduino VIN pins to supply the module's peak current without stressing the onboard 5V regulator.

Suitable for

• Arduino projects requiring internet access (LAN, Wi‑Fi or 3G)
• Applications needing additional removable storage via USB flash
• Development and prototyping with Uno, Leonardo, Duemilanove, Diecimila and Mega

Key specifications

• System: OpenWrt (open source Linux)
• Arduino IDE compatibility: v1.5.4 and later
• Network interfaces: LAN port, Wi‑Fi, 3G dongle support
• Storage: USB flash support for project storage
• Power: requires up to 200 mA at full load; powered via Arduino VIN pins
• Antenna: external antenna for improved wireless stability

How to use

Mount the 4duino_Yun_Shield onto the Arduino board headers (Uno, Mega, etc.), connect power to the Arduino VIN pin so the module receives sufficient current, then configure network settings through the web GUI or via SSH. Use the Arduino IDE (v1.5.4 or later) to upload sketches to the Arduino board; manage the Linux side and perform software upgrades over the network as needed.

Recommendations

For stable wireless operation place the external antenna clear of large metal objects and ensure the Arduino VIN supply can provide the module’s peak current (~200 mA). Use a reliable USB flash drive formatted for cross-platform use when attaching external storage.
