3DR Radio Telemetry Kit 433MHz 500mW The 3DR Radio Telemetry Kit has a 433Mhz frequency band and Receiver sensitivity to -124 dBm. This 3dr telemetry kit allows you to link to a flight controller to a USB or UART-equipped device such as a computer, laptop or tablet supporting a USB connection (OTG). The Radio set lets you see live data, such as live GPS position overlaid on a map, system voltage, heading, waypoint navigation and much more. The system utilizes the 433MHz band and provides a full-duplex link using HopeRF’s HM-TRP modules running custom, open-source, firmware. Using open-source MAVlink based ground station software, you can even fly your aircraft with a joystick via your computer and update settings live! Or just use it for your DIY projects that need a wireless Serial interface. This kit offers a great low price, longer range, and superior performance. The system utilizes the 433MHz band and provides a full-duplex link using HopeRF’s HM-TRP modules running custom, open-source, firmware. Features : MAVLink protocol framing status documents Frequency modulation and Spread Spectrum (FHSS) Self-adaption to time-division multiplexing Support LBT and AFA Configurable duty cycle Built-in error-correcting code(up to 25% data bit error) AT command configure data transmission RT command remote control data transmission Interchangeable air and ground 433MHz modules Micro-USB port 6-position Molex connector 500 mW maximum output power (adjustable) SMA connector 2-way full-duplex communication through adaptive TDM UART interface Transparent serial link Open-source SIK firmware Configurable through *Mission Planner and *APM Planner Based on the HM-TRP wireless module, with Si1000 8051 microcontroller and Si4432 wireless module

3mm DIP Diffused Blue Led (Pack of 10) A  Blue light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for another lighting. It looks like a blue led and it luminate blue light. The series is specially designed for applications requiring higher brightness. The led lamps are available in different colours, intensities. Wondering what is difference between diffused LEDs and normal clear LEDs? A Normal LED has a clear and transparent material. They are little brighter as the transparency of the lens does not allow absorption or dispersion of the light. While Diffused LED looks cloudy and are translucent because of which the light gets diffuse evenly in all the direction. Applications: Can be used in DIY projects for indication Can be used in small toys Can be used in robotic cars

3 mm Green LED (Pack of 10) A Green light-emitting diode (LED) is a semiconductor light source. LED's are used as indicator lamps in many devices and are increasingly used for other lighting. It looks like a white led and illuminate's blue light. When a light-emitting diode is switched on, electrons are able to recombine with holes within the device, releasing energy in the form of photons. This effect is called electroluminescence and the colour of the light (corresponding to the energy of the photon) is determined by the energy bandgap of the semiconductor.

3mm IR Pair This pair of 3mm IR High-power directional IR LED and Filtered photodiode can be used in various kinds of sensing circuits. The narrow beamwidth IR LED emits focused IR light and the filtered photodiode filters out ambient light without the need for any external circuit. When used with a proper circuit it can give up to 200 mm of reflective sensing and can also be used in high-speed applications like encoders. It has a peak wavelength of 940nm.IR sensors are also used in IR imaging devices, optical power meters, sorting devices, missile guidance, remote sensing, flame monitors, moisture analyzers, night vision devices, infrared astronomy, rail safety, etc. Applications of IR Transmitter & Receiver Pair: IP cameras Gas Analyzers Alarm systems and other crime prevention devices Battery-driven human presence sensors for IoT smart homes IR sensors are also used in IR imaging devices, optical power meters, sorting devices, missile guidance, remote sensing, flame monitors, moisture analyzers, night vision devices, infrared astronomy, rail safety, etc.
