- Use the WS2812S chip
- RGB color lights
- Each LED can be controlled individually
- You only need one control line and two power cables
- Arduino libraries and routines available
- Density of the PCB: 0.8 mm
- Size: 20x3 mm

SparkFun Hamburger speaker is a high quality speaker in a small form and with even smaller price. You wouldn't believe you can get a quality product for less than 7€, right? Well, we couldn't believe that as well, but SparkFun makes that possible.

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.
