Grove module with a red LED light. Ideal for quick and easy connections thanks to the Seeed Grove connector.

Set of 300 diodes packed in a handy box. Lens colour: red, green, yellow, yellow, blue - diffuse, light white.

The perfect solution for not worrying about the length required on your RGB LED strip, now with a WiFi driver compatible with the eWeLink APP and voice assistants like Google Home or Alexa. Also includes a 24-key IR remote control.

You will be able to turn on and control your strip lights anytime and anywhere, and control it with just a click on your smart phone or tablet via APP eWeLink, or voice assistants, without time and distance limitations.

Red, yellow and green LED traffic light mini kit ideal for educational and beginner Arduino projects.

Addressable 5050 RGB LED bar (5mm x 5mm) with low current draw. LEDs can be joined by connecting the output of one module to the input of another.
Data line with a very specific protocol, requires a real-time microcontroller AVR, Arduino, PIC, mbed, etc. A minimum 8 MHz processor is required.

Mount LED Diode on a good heatsink, a metal plate, add some fan, this is necessary because you have to " remove "the heat from the surface of the plate so that the LEDs last longer to place a little bit of thermal silicone in each of the centers of placement of the diodes.
The thermal paste increases the thermal transfer between the diode and the metal plate used as a circuit.
Important to keep in mind the diodes generate a lot of light intensity and very concentrated.
Avoid looking directly at them once they are turned on and wear protective glasses when working with them.
Characteristic:
- Chip 28x47mil
- Voltage: 3.0-3.2V
- Current: 300mA - Luminous flux: 120-130LM
- Beam angle: 130 degrees

COB LEDs are built as a matrix of LEDs, that is, a concentration of LEDs in a silicone coated tablet. The advantages of LED COB: - a light output of up to 120 lumens / watt (twice as much as LED SMD)
- the light intensity is greater without the need to concentrate the beam of light
- greater durability
- opening angle of up to 160ºC
- multidirectional light Mount LED diode on a good heatsink, add some fan, this is necessary because you have to "remove" the heat from the surface of the plate so that the LEDs last longer to place a little bit of thermal silicone in each of the placement centers. the diodes.
The thermal paste increases the thermal transfer between the diode and the metal plate used as a circuit.
