The first Raspberry microcontroller with the proprietary RP2040 chip and a dual-core Arm Cortex-M0+, the Foundation's cost-effective yet highly flexible solution. Designed for high performance and with a high degree of digital interfaces. Programming in C/ C++ and MicroPython.

3.5mm Audio Jack Breakout Headphone Video Audio MP3 Jack Module. This female jack connector adapter 3.5mm audio soldered on a PCB board, it is ideal to use in our projects. TRRS connectors are the audio-style connectors seen on some phones, MP3 players and development boards. TRRS stands for "Tip, Ring, Ring, Sleeve", reflecting the fact that unlike a standard stereo connector, this one actually has three conductors and a ground.

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
