3DR Radio Telemetry 433MHz 500mW(X6) This set of 3DR Radio Telemetry Module 433MHz 500mW allows you to establish a connection between a flight controller and a USB or UART-enabled device, such as a computer, laptop, or tablet with USB compatibility (OTG). The latest version 2 radios no longer require a separate Air/Ground module, as both transceivers can now use both UART or USB connections, and support both modes. This radio set not only allows you to view real-time data, such as live GPS position overlaid on a map, system voltage, heading, waypoint navigation, and even an artificial horizon, but also offers much more. By using an open-source MAVlink based ground station software, you can even fly your aircraft with a joystick via your computer and update settings in real-time. Alternatively, you can use it for your DIY projects that require a wireless Serial interface. This kit is cost-effective, has longer range, and offers superior performance. The system operates on the 433MHz band and provides a full-duplex link using HopeRF’s HM-TRP modules running custom, open-source firmware.

24V RGB 5050 SMD LED Strip Flexible 5M/Roll NO Waterproof 24V RGB 5050 SMD LED Strip with 1Meter length has 300 Bright, RGB LEDs on the single strip!  The strip is comprised of 5050 Sized SMD RGB LEDs and draws a total of 22.5 Watts of Power. This RGB 5050 SMD LED Strip strip is flexible and can be bent to conform to curves and corners. Runs from 24VDC. (Power supply and controller not included) You need a minimum output 2 AMPs Adapter to power this full 1 Meter strip. Using an underpowered power supply on these strips will result in power loss down the line and mismatched colors due to a certain color of diodes not receiving enough power. These strips are a bit different because, though they have the same number of LED modules (300) in another Cold white or Warm White roll, they actually have three times the light-emitting diodes as a regular LED strips. This is because each of the 300 modules on the strip each contains three colors. A red, a blue and a green LED. This means that, when set to white, at full brightness, the RGB strips use almost three times the power as the regular white strips. A 1 Meter roll of RGB LEDs uses roughly 2.8 Amps at 24VDC. So connecting three of these strips, end-to-end would result in roughly an 8.4 Amp requirement. With this you can create different ambience at the comfort of your hands just by switching lights on and the designer sequence of lights that are already preset. These lights can be used as decorative pieces around the house especially during festive occasions, office buildings, walls etc. or for any functions to brighten the occasion. read more : NEOPIXEL WORKING AND DEMO Note : These are NOT individually addressable LED strips. Each color has its own separate 24VDC circuit. For a total of three 24VDC circuits (R G B). You can power these strips off of regular 24V DC if you don’t need advanced flashing patterns or color mixing. Application: Ideal for decoration of building outlines, landscape illumination, amusement themes. Holiday light sculpture, decorative figure, active signs, displays, shop windows Storefronts, bar, nightclub, street, sidewalk, deck, park, porch, staircase, railing, ceiling, or driveway.
