7-segment LED display, 1 digit 7mm, green color (570nm), 4000 ucd (10mA), common cathode, Pb-free. LED1-AS-B-02811AG

A reflective sensor that precisely measures the intensity of light reflected from a surface using an IR LED and a phototransistor. It offers a long detection range—optimally around 20 mm, and up to 80 mm—thanks to the QTRXL sensor with a built-in lens and adjustable LED brightness. It generates a digital RC signal that\'s easily read by microcontrollers like Arduino or Raspberry Pi. Pololu 4540

WiFi controller supporting IEEE 802.11b/g/n standards in the 2.4GHz band, ideal for integration with embedded systems requiring reliable wireless communication. With SPI and UART interfaces and the ability to easily update the software, it is a versatile and energy-efficient solution that works well in IoT applications, automation systems and mobile devices. Segger emPower WiFi Module - Atmel ATWILC1000 (6.37.01)

Surface-mounted IT socket with two shielded RJ-45 category 6 ports, designed for high-speed networks, offers universal IDC/LSA connectors, simple installation, and supports 26-22 AWG cables. Lanberg OS6-0002-W

LED 5 mm two-color angle 40 degrees common cathode, RED - luminous 1200 mcd (20mA) (2.0V); df 635 nm, Pure Green - light intensity 1200 mcd (20mA) (2.1V); df 519 nm

The step-down converter module allows for voltage reduction from 8.4–60 V to a stable 8.4 V at currents up to 10 A. High efficiency of up to 95% and low power losses make it ideal for applications requiring high current and stable power. The device features built-in overcurrent, thermal, and reverse connection protection, as well as a soft-start function and a Power Good indication. Pololu 5675

Quartz resonator, housing HC49S (low), RoHS

High-quality digital-to-analog converter that allows for pure stereo audio playback without the need for I2C configuration or the MCLK pin. It supports I2S signals (BCLK, WSEL, DIN) and audio formats up to 32 bits and 384 kHz, providing an excellent signal-to-noise ratio (110 dB). Audio output is available via a 3.5 mm jack or on-board pads, and the module works best as a line output to amplifiers and audio systems. Adafruit 6251
