The Arduino Ethernet Shield 2 allows an Arduino Board to connect to the internet. It is based on the Wiznet W5500 Ethernet chip. The Wiznet W5500 provides a network (IP) stack capable of both TCP and UDP. There is an onboard micro-SD card slot, which can be used to store files for serving over the network. It is compatible with the Arduino Uno and Mega

Audio amplifier module with three output channels. It can be powered with the voltage from 12 to 24 V and has two outputs with a power of 50 W (left and right) and one with a power of 100 W (bass)

32-bit microcontroller from the STM32F4 family with ARM Cortex-M4 core, 1024kB Flash memory, 192kB RAM, 168MHz, CAN, I2C, IrDA, LIN, SPI, UART / USART, USB OTG, Brown-out Detect / Reset, DMA, I2S, LCD, POR, PWM, WDT, 1.8 ... 3.6 V, A / D 16x12b, D / A 2x12b, 100-LQFP

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 6 V. The board measures only 0.7″ × 0.7″, but it allows a typical continuous output current of up to 2.5 A. Typical efficiencies of 85% to 95% make this regulator well suited for powering moderate loads like sensors or small motors.

The module allows measuring the light around the sensor. The measuring range is in the range 1 - 65535 LUX, and communication takes place using the I2C bus. modBH1750 (GY-302)
