USB port isolator with ADUM3160

Audio preamplifier based on the NE5532 chip. Powered with DC voltage in the range from 9 to 35 V (does not require symmetrical voltage)

Crossover for tweeters with a crossover frequency of 3400 Hz. It works with speakers with an impedance of 4 to 8 Ω and offers power up to 60 W

A module for the detection of gases and vapors of alcohols, including ethanol.

The module allows you to send UART (TTL) bus signals to a computer via a USB port. The adapter operates based on the PL2303HX chip and is recognized in the computer as a virtual serial port

The MQ-6 sensor allows the measurement of LPG, propane and isobutane. The measuring range of the sensor is in the range of 300 - 10.000 ppm, while the output receives an analog signal.

Pololu High-Power Motor Driver 24v12

Module with a button, LED diode and a blue cap. DFRobot DFR0029-B

Data logger dedicated to Feather plates. Equipped with RTC clock, battery slot and micro SD card slot. Adafruit 2922

The Step-Down converter module on the XL7015 chip converts the voltage in the range of 5-80V to 5-20V, with a maximum current of 0.8A and a recommended output power of 7W. It has protection against overheating, short circuit and current overload, and its board size is 16 x 44 mm.

The PicoBuck LED Driver is an economical and easy to use driver that will allow you to control and blend three different LEDs on three different channels. By default, each channel is driven at 330mA; that current can be reduced by either presenting an analog voltage or a PWM signal to the board. COM-13705
