Buzzer 5V Active Buzzer 4 to 7V DC

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.

This fingeprint scanner from ADH-Tech combines a highly precise fingerprint sensor module with an onboard MCU and UART interface enabling trivially very connection to any project.

The scanner independently reads and analyses the fingerprint thanks to an MCU algorithm that can send a converted digital signal to a peripheral serial interface for a data read. The onboard MCU algorithm enables operations such as for example a fingerprint enroll.

SONOFF D1 Smart Dimmer Switch is a smart dimmer switch that offers smart light control solutions perfect for your home or workplace, controlled either by the eWeLink application, via 433MHz RF control or by voice assistants such as Alexa or Google Home.
