4-digit, 8-segment LED display module with 8-level brightness adjustment. Communication via the I2C interface. DFRobot DFR0645-G
X-NUCLEO-IDS01A4 is a development board STM32 Nucleo that allows the use of the RF SPSGRF-868 module for the ISM band (868 MHz carrier).
2.8" display with 320x240 16-bit color pixels and a capacitive touch overlay fits perfectly onto the Raspberry Pi 3/2/A+/B+. The display and touchscreen uses the hardware I2C Pins (SDA & SCL), SPI pins (SCK, MOSI, MISO, CE0) as well as GPIO #25 and #24. Adafruit 2423
Pololu Universal Aluminum Mounting Hub for 3mm Shaft Pair, 2-56 Holes
USB port isolator based on the ADUM3160 chip. It has a built-in galvanically isolated voltage converter and is powered from the USB port
The driver with the TPIC6C596 system allows you to control 7-segment displays using three signal lines. Serial connection of controllers is possible. SparkFun WIG-13279
This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. This unit works great from 5 to 12V (datasheet shows 12V). You can also install a jumper wire past the 5V regulator on board to make this unit work at 3.3V. Sensor uses 1.6mA@3.3V. SEN-13285
Isolated RS485 module with signal amplifier function. Designed for communication within industrial networks. YN2209
This disc load cell (sometimes called a strain gauge) can translate up to a whopping 200kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and proportional of, the strain (e.g. pressure or force) applied to the disc. SEN-13332
Contrast sensor module. It has two integrated operating modes: analog and digital. It has the ability to set the digital mode for color detection. DFRobot SEN0147
Module with green LED, digitally controlled. Perfect for people starting to play with Arduino. Equipped with a Gravity interface. DFRobot DFR0031-G
Digital oscilloscope equipped with a 7" TFT LCD display. It has four measurement channels with a 50 MHz bandwidth, a sampling rate of 1 GSa/s and a 24 Mpts memory buffer. Rigol DS1054Z
32-bit microcontroller from the STM32F7 family with ARM Cortex-M7 core, 512kB Flash memory, 320kB SRAM, I2C, SPI, UART / USART memory, USB, CAN, 1.7 ... 3.6V, 144LQFP, STM, RoHS
Module with red LED, digitally controlled. Perfect for people starting to play with Arduino. Equipped with a Gravity interface. DFRobot DFR0031-R
Module with white LED, digitally controlled. Perfect for people starting to play with Arduino. Equipped with a Gravity interface. DFRobot DFR0031-W
Module with yellow LED, digitally controlled. Perfect for people starting to play with Arduino. Equipped with a Gravity interface. DFRobot DFR0031-Y
Multifunction USB tester. It allows you to check the voltage and current flowing through the USB socket and to control the capacity, energy, power, temperature and impedance. AT34
FRAM memory with a capacity of 4kbit by Cypress Semiconductor, communicates via the I2C bus, the power supply voltage is in the range 2.7 - 3.6V. The system has an SOIC8 housing
