4G LTE router ensuring a stable and fast connection to the Internet. It has 4 LAN ports, one WAN and an RS232/RS485 port. Supports Modbus RTU to TCP protocol. It offers mounting on a DIN rail and a metal housing with IP30 protection class. USR-G809-E

The X-NUCLEO-NFC02A1 is a dynamic NFC/RFID tag board based on M24LR04E-R, for expansion of STM32 Nucleo boards

RJ45 Network Plug Lanberg Cat. 5e FTP (100 pcs) A set of 100 shielded RJ-45 [8P8C] network plugs, Cat. 5e, designed primarily for LAN FTP cables.

Thanks to the use of triple prongs (3prong), Lanberg plugs are compatible with both types of cables: solid and stranded.
Solid wire consists of a single piece of metal wire (used in structural installations).
Stranded wire consists of a bundle of thinner wires (used in patch cords and shorter lengths).

Micro SD card module

A set of 10 cables, 50 cm long, compliant with the Gravity standard. DFRobot FIT0773

Easy to use app builder that allows users to add a variety of buttons, sliders, graphical displays and even RGB controllers to their phone. The SparkFun Blynk Board is specially designed to work with the ‘widgets’ within the Blynk mobile app to create your next IoT project. WRL-13794

Extending tile dedicated to ESP Thread Border Router. It allows you to add an Ethernet interface. Sparkfun WRL-25498

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

Advanced wireless communication module, based on the Bluetooth 5.4 stack (Bluetooth® Low Energy, BLE), which was designed using the efficient Nordic NRF52805 SOC system. The module offers support for the UART interface, available only in peripheral mode, which allows for effective operation as a data bridge (Data Bridge). Sparkfun WRL-25467

The module allows you to attach a strain gauge (working in the Wheatstone bridge circuit) and convert the analog signal into its digital representation, available on the module output lines. The system processes the signal with a 24-bit resolution and can be powered by 2.7V - 5.5V. The module is especially recommended for constructing digital scales in combination with Arduino

An advanced wireless communication module based on the Bluetooth 5.2 (Bluetooth® Low Energy, BLE) stack, which is designed using the powerful Nordic nRF5340 SoC. It provides GPIO, SPI, UART, TWI, I2C, PDM, PWM, ADC, NFC and USB interfaces for connecting peripherals and sensors. SparkFun WRL-25465

Sound module supported by I2C interface, which allows to generate sound signals in simple projects thanks to Qwiic system and ATtiny84 microcontroller. With support of Arduino libraries, users can control volume, frequency and duration of sound, which makes it ideal for applications such as alarms or signals in robots. SparkFun BOB-24474
