Power supply 9V 2A 18W USB-C

433.92 MHz radio receiver module that allows you to also control it via a radio remote control. You can control each channel either by remote control, the free APP "eWeLink" or with wizards such as Alexa or Google Home. This will allow you to create scenes, schedules, and much more. Its relay supports up to 4 devices simultaneously. Each device can be powered by 5-24 V DC.

Digispark is a development board based on the ATTINY85 microcontroller from ATMEL born in a successful campaign on Kickstarter.
Similar to the Arduino line , It is one of the smallest boards on the market.
Programmable directly from USB with the same Arduino tools. It has a built-in Micronucleus bootloader and can be replaced by similar ones such as the Trinket bootloader. Adafruit or others.
You can use many of the same Arduino libraries and have your own on the digispark wiki. Attiny85 Digispark USB Development Board features:
-USB power supply
-External power supply (7v-35v DC 12v maximum recommended)
-5V DC 500mA regulator on board
-Programmable with the Arduino IDE
-Loaded with Micronucleus bootloader

OTG micro-SD multifunctional card reader adapter with USB 2.0 type A connectors. Allows you to transfer data from the card to your computer. Supports microSD/T-Flash, microSDHC cards. The reader in combination with a micro card can serve as a Pen Drive.

Shield allows you to be directly punched to an Arduino Uno, Mega board and convert your Arduino board into a controller like the game console system. Joystick Shield compatible with Arduino UNO Mega features:

Nano 33 IoT as the name would suggest is an WiFi enabled version of the famous Nano. It has an upgraded microcontroller to ARM Cortex SAMD21 y el módulo NINA-W10 (based on ESP32) from u-blox and a module IMU LSM6DS3.

The 17 x 7 rectangular matrix has a total of 119 white LEDs that can be controlled individually. A dedicated extension to the Raspberry Pi Pico. The device uses the 12C bus for communication and can be safely powered via the USB port.

The module has two outputs: analog A0 and digital D0.
digital output D0 - signal 0 or 1 appears depending on the configuration of threshold.
The threshold is fixed with the potentiometer. Characteristic: - Operating voltage: 3.3V -5 V - Sensitivity adjustable by potentiometer
- Dual output mode: analog and digital
- Red LED - power indicator
- Green LED - digital switching output indicator
- Measurements PCB: 3 x 1.5 cm
- Sensor measurements: 5.4 x 3.9 cm
