Yun Shield w/ Leonardo Basically, a Yun Shield + Leonardo equal the official Arduino Yun, but the Yun Shield is more flexible because it can work with other Arduino board such as Uno, Duemilanove, Mega etc. The Yun Shield uses external an wifi antenna which provides stability and the possibility for various configurations and environments. Hardware version info Difference between v1.x and v2.x v1.x and v2.x are both provided, they difference between them are: • v1.x can be powered by DC or USB port from Arduino, while v2.x can only be powered by DC port. • v2.x support Micro SD card • v2.x support two USB host ports, while v1.x only support 1 USB host Port. For v1.x series • Yun Shield v1.0: The first hardware release for the Yun Shield. • Yun Shield v1.1: Minor change from v1.0 according to feedback from customers. • Yun Shield v1.1.6: • Add Passive PoE port,Yun Shield can be powered by PoE Injector now • Change the design to auto works with 3.3v or 5v Arduino.

Learn how to set up an IR remote and receiver on the Arduino, how IR transmission works, and how to control the Arduino's output pins with a remote control. Krishna Pattabiraman is a frequent guest writer on Circuit Basics and the founder of www.codelectron.com. JLCPCB - Only $2 for 10 PCBs. For some reason the program never finishes. Feb 2, 2017 - Compatible with Arduino Leonardo, Uno, Duemilanove, Diecimila, Mega. USB port just like the Arduino - no special programmer is needed.

No need to manually select jumper. • Level Shift is now can output more current. This increase the compatibility with different Arduino boards. Change Log from Yun Shield v1.1 to v1.1.6 For v2.x series • Yun Shield v2.3: • Add an extra USB port, • Add Micro SD card slot. • v2.3 needs more power than the v1.1 in the USB part, so modified the power supply section to let it be powered by a DC adapter only. • Yun Shield v2.4: • Add Passive PoE port, Yun Shield can be powered by PoE Injector now.

• Change the design to auto works with 3.3v or 5v Arduino. No need to manually select jumper. • Level Shift is now can output more current.

This increase the compatibility with different Arduino boards. Yun Shield v2.4 difference Specifications • Processor: 400MHz, 24K MIPS • Flash: 16MBytes • RAM: 64MBytes • Power Input: 4.75v ~ 23v via Arduino VIN pin • 1 x 10M/100M RJ45 connector • 150M WiFi 802.11 b/g/n • External Antenna via I-Pex connector • 1 x USB 2.0 host connector, used for USB storage or 3G connection • 1 x Reset button • Compatible with 3.3v or 5v I/O Arduino. Features • Open source Linux (OpenWrt) onboard • Low power consumption • Compatible with Arduino IDE 1.5.4 or later, user can program, debug or upload sketches to the Arduino board via the Arduino IDE. • Managed by Web GUI, SSH via LAN or WiFi • Software upgradable via network • Built-in web server • Supports internet connection via LAN port, WiFi or 3G dongle. • Supports USB flash to provide storage for Arduino projects. • Failsafe design provides robust system.

• Compatible with Arduino Leonardo, Uno, Duemilanove, Diecimila, Mega LEDs There are four LEDs on the Yun Shield. The functions of these LEDs are: • PWR: Power Indicate LED. Turns on once there is power. • LAN: Indicates there is a LAN connection when it is on or blinking. • WLAN: Indicate WiFi status. • SYS: LED for USB storage. It is on if the USB flash is linked to the Arduino Yun default SD directory /mnt/sd and /www/sd System Structure.
