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.

Ideal for connecting TTL RS232 devices to your PC through the USB port. PL2303HX PL2303 USB to UART TTL Cable Module RS232 Converter 4 Pin features:
- Compatible controller PL2303HXA
- 4 pins: 5.0V (red), TxR (green), RxD (white), GND (black)
- 2.5A self-recovery protective fuse
- Supported OS: Win8, Win10, WinME, Win2003, Win XP, Vista, Win 7 The 64-bit Prolific drivers provided by Microsoft through Windows Update will not work with most adapters and will therefore generate the generic "Code 10" error.

This module equipped with a PCF8591 converter has a low current power supply and includes 8 bit CMOS data acquisition devices.
Your converter has four analog inputs, one analog output and one I2C serial bus interface.
It is supplied in the voltage range 2.5V-6V, analog voltage between the negative potential VSS and positive VDD. The control and data signals are transmitted on the two-wire I2C bi-directional bus to the transformed series.
The intensity of the ambient light can be converted into a digital signal thanks to its integrated photoresistor.
It allows access to eight PCF8591 converters on the same I2C bus without additional equipment. Converter Module AD-DA PCF8591 - Analog Voltage 2.5V-6V features:
- Supply voltage (between VSS and VDD): 2.5-6VDC
