This little board is great for any type of prototyping - enables troubleshooting and debugging of any board with voltage from 0 to 5.5V. The  board interprets the commands and sends them further via a proper protocol (ranging from UART through I2C up to HDD44780 LCD). The Pirate lets analyze as well the data sent back from the device to the computer terminal effectively allowing to decipher potential errors. The bootloader installed on the board enables the quick and easy update of firmware and changing the functionality of the board.

This board features PIC24FJ64 and FT232RL USB-to-serial chip enabling swift communication over the mini-B USB port. On the other end of the board 2x5 pin header is placed with detailed descriptions of each pin.

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.

This module is a three-way switch (COM, NO and NC) that uses the intensity of the ambient light to directly control the output load. Its adjustment potentiometer allows you to change the sensitivity and set the threshold for starting the relay. The relay is energized when it is darker than the threshold.
The optical isolation relay effectively protects the chip and ensures better performance.
This module is used for light detection, brightness detection , control of lamps and automatic equipment. Characteristic: - Channels: 1
- Supply voltage: 12VDC
- Output load capacity: 250V 10A AC / 30V 10A DC
- Relay activation current: & gt; 100mA
- Insulation: Yes
- Indicator LED: Green and Red
- PCB size: 5x2.6 cm / 1.96x1.02 "

The amplifier with high efficiency, in case of 12 V power supply can output 10 W + 10 W power.
