Speed controller for DC motor (PWM) 10V-30VDC 120W 5A 10A

Mount LED Diode on a good heatsink, a metal plate, add a fan, this is necessary because you have to "remove" the heat from the surface of the board so that the LEDs last longer to place a little bit of thermal silicone in each of the diode's placement centers.
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: - 32mil Chip
- Voltage: 3.2-3.4V 
- Current: 350mA 
- Luminous flux: 100-110LM 
- Ã beam angle: 140 degrees 
- Color emission: pink

This BLtouch sensor is an automatic leveling sensor for 3D printers that can accurately measure the inclination of your printing surface.
It can greatly improve the printing precision of your 3D printer.
Its features: are simple, smart and precise.
It could work with almost any type of bedding, such as glass, wood , metals, etc. 3DTouch's main functions and controls are the same as most automatic bed leveling sensors, consisting of an RC servo and a micro switch.

Self-leveling sensor BLtouch 3D printer features:
- Supply voltage: 5V.
- Supply current: 15mA
- Max. Current: 300mA
- Len3Dh cable: 150mm
- Wiring:
- 3 pins: Brown (-, GND) Red (+ 5V) Orange (control signal)

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 concentrating the beam of light
- Greater durability
- Angle of opening 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.

LCD display consists of a 16-character, 2-rows.
The display is compatible with the HD44780 controller
Ideal for projects with Arduino
You can use it with PIC, AVR, STM32 and many more controllers.
