X-CAM A10-3H 3 Axis 360Deg Rotation GoPro Gimbal With A/V Link
close

The X-CAM A10-3H Gimbal it at the top of the list when it comes to gimbals, the A10 has True continuous rotation 3-Axis ability with A/V Video link transfer. Full control over Roll, Tilt, Yaw, Mode and Zero home. And charging with A/V out transfer for the GoPro hero camera

The X-CAM A10-3H Gimbal it at the top of the list when it comes to gimbals, the A10 has True continuous rotation 3-Axis ability with A/V Video link transfer. Full control over Roll, Tilt, Yaw, Mode and Zero home. And charging with A/V out transfer for the GoPro hero camera.

There are a lot of 3 Axis gimbals on the market, but only a few that use a slipper for true 360Deg continues rotation and also transfers the A/V output from the GoPro to the top controller for VTX use. The A/V line also powers/charges the GoPro. Another key feature on the X-CAM is its ability to go to zero or home using referencing sensors, this is great for when transitioning from a yaw control to a forward flight mode the gimbal will auto go to the front position.

The A10 uses an advanced method of vibration control and mounting and is a full CNC aluminum frame design with integrated motors for a light 280g weight.

If you’re serious about some aerial Photography with a GoPro this is the gimbal for you

INTRODUCTION

Yun Shield is one of the most powerful shields for Arduino Board. Yun Shield is designed to solve the Internet connectivity and storage issue for Arduino Board. It provides a linux system, WiFi, Ethernet and USB (can used for camara, storage, 3G etc) to Arduino.

Yun Shield runs Open Source OpenWrt system (Same system as runs in Arduino Yun) and it is fully compatible with Arduino IDE v1.5.4 or later. Yun Shield is the ideally choice for Arduino Projects which require various internet connections and more storage.

Basically, Yun Shield + Leonardo equally to the official Arduino Yun, but Yun Shield is more flexible because it can works with other Arduino board such as Uno, Duemilanove, Mega etc. And Yun Shield use external wifi antenna which provides stability and possibility for various environments.

  • Compatible with Arduino IDE 1.5.4 or later, user can program, debug or upload sketch to Arduino board via Arduino IDE.
  • Managed by Web GUI, SSH via LAN or WiFi
  • Software upgradable via network
  • Built-in web server
  • Support internet connection via LAN port, WiFi or 3G dongle.
  • Support USB flash to provide storage for Arduino projects.
  • Failsafe design provides robustly system.
  • Compatible with Arduino Leonardo, Uno , Duemilanove, Diecimila, Mega.

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
