The A-Star 32U4 Mini LV is a programmable module based on the ATmega32U4 from Atmel. Unlike competing products, it has an onboard switching step-up/step-down regulator that allows it to be powered efficiently from a 2.7 V to 11.8 V supply. Pololu 3103

4-digit, 8-segment LED display module with 8-level brightness adjustment. Communication via the I2C interface. DFRobot DFR0645-G

Module with 2 relays controlled by the I2C interface. Each relay can switch currents up to 25 A at 12 to 280 V AC. SparkFun COM-16810

A set with a temperature sensor based on the DS18B20 system in the form of a waterproof measuring probe, a sensor adapter and a cable. Communication via the 1-Wire interface. DFRobot KIT0021

Module with an analog sensor of carbon monoxide and combustible gases (methane, propane) MQ9. It is powered with the voltage of 5 V and has an analog output. DFRobot SEN0134

The STM32 Nucleo pack for USB Type-C^™ and Power Delivery (P-NUCLEO-USB001) is a development tool for learning and developing solutions based on USB Type-C^™ and USB Power Delivery technologies

Adafruit 1088

A set with a Doppler radar module and an XIAO ESP32C3 board designed for precise detection of human presence. It allows you to connect additional Grove sensors (analog or with an I2C interface) and expand the functionality. Seeed Studio 110061541

The Wio Helium Monitor is a plug-and-play LongFi hotspot monitor for the Helium network. It allows you to determine whether a device is connected to the local area network (LAN) and whether it has access to the Internet. With Grove-Wio-E5 and an activated Watchium Silver/Gold subscription, you can also check that LoRaWAN communication with the hotspot (including Witness) is working correctly. Seeed Studio 114992990

Adafruit Feather 328P is a module with a built-in ATmega 328P AVR microcontroller (8MHz, 32kB Flash, 2kB RAM). The board is compatible with Arduino IDE, has small dimensions and low weight, and the built-in USB connector allows programming and debugging. Adafruit 3458

Graphical display, users may show off graphs, full-color pictures, text, and anything else they want to see by communicating with it through SPI. Digilent 410-323

Real time clock (RTC) module PCF8523. It uses the STEMMA QT connector and communicates via the I2C interface. Adafruit 5189

A development kit that allows the development of applications using the STM32H7 microcontroller with ARM Cortex-M7 core and Cortex-M4 (dual core). The STMod + and Arduino Uno V3 connectors allow you to add external peripherals. STMicroelectronics STM32H745I-DISCO

Development board with Espressif ESP32-S3R8 WiFi and Bluetooth LE module equipped with a dual-core Xtensa 32-bit LX7 processor. It offers 16 MB Flash memory and 8 MB PSRAM. The pins available on the board are compatible with Arduino Nano ESP32. Waveshare ESP32-S3-Nano
