This set includes NE555 Timers, LM324 Amplifiers, 8-bit Shift Registers, Quadruple Bus Buffer Ports, L293D Motor Drivers and Darlington ULN2003 and ULN2803 Transistor Arrays.

Switch and amplify your electronic signals in high power applications with the help of this kit! Includes the IRFZ44N, IRF540N, IRFP460, FQP47P06, IRL540, IRLZ44, NTP60N06L, FQP27P06, an isolated port with IGB 17A high speed bipolar transistor.

Control your Arduino projects from anywhere in the world with a free app thanks to the Tuya IoT interface! Connect the Module of Tuya IoT Interface to your Arduino using the 4 included male wires. Then, connect your Arduino to the Cloud IoT Tuya simply by installing the Tuyav library, which is compatible with ATmega Chipsets (or AVR Platform). This will allow you to connect to the Tuya app via WiFi and allow you to control up to 5 outputs.

The VMA214/RFM69HC Transceiver Module operates over a wide frequency range, including license exempt ISM (Industry Scientific and Medical) frequency bands 315, 433, 868 and 915MHz. All major RF communication parameters are programmable and most can be configured dynamically.

This package includes a Sensor of Level of Water and a Sensor of Humidity from Solo. If the plates have water covering the sensor components, an analog value will be available on the "SIG" connection. The Sensor of Level of Water can detect up to 4cm of water. This way, you can check if your aquarium, or your pet's water bowl, still has enough water. You can use the Sensor of Moisture of the Soil to check your plant's soil or growing environment, for example.

Play your .mp3 files stored by USB or SD card. For Use (12V): Place a 68Ohm/1W Resistor in series with the (+) of the Power Supply, to avoid excessive dissipation.

A large LED array panel of dots to connect to your PI, Arduino and more! This large, bright 512 LEDs  has integrated controller circuits designed to facilitate direct use on your board.

The Vma449 integrates the Voice Recorder ISD1820 and Playback CI to record a single message up to 20 seconds long. The recorded message is stored in the analog flash memory that keeps the message stored even in the event of a power failure. The module has an integrated microphone to record your message and buttons for recording, partial playback or full reproduction of the message functions.

The Vma210 Expansion Board is designed to allow easy access to the interface pins of an Arduino Nano. Each DIO pin or analog pin on the Nano is brought to an appropriate header.
