Beam is a beginner-friendly PCB with 120 LEDs arranged in a 5x24 grid, a great size to display text or animations in your project. Plug in one to four to create a long blinky display that can be controlled by any 3-5V microcontroller or microcomputer (e.g. Arduino, Raspberry Pi, Particle, and more). Adafruit 3668

Limit switch without SPDT lever. Used, among other things, in computer mice

The S9V11F5S6CMA switching step-up/step-down regulator efficiently produces a fixed 5 V (default) or 6 V (selectable) output whether it is higher or lower than the input voltage, which can range from 2 V to 16 V. (Note: minimum start-up voltage is 3 V, but it operates to 2 V after that.)

The Pmod BLE module is a Bluetooth module with powerful capabilities. Thanks to communication via the UART port, the module can be connected to any platform equipped with this interface. The module is equipped with the Roving Networks RN4870 system, in which a full Bluetooth interface is built-in. Digilent 410-359

Module with the 3-axis MMA8452Q accelerometer. The system has a user selectable measurement scale of ±2g/±4g/±8g. There are two Qwiic connectors on the board and holes with 2.54 mm raster. SparkFun SEN-14587

Finder 22.22.8.230.4000 is a modular installation relay with two normally open (NO) contacts, each with a 20 A load capacity at 250 V AC, made of AgSnO₂ contact material. The relay is designed for DIN rail mounting (17.4 mm width) and operates with a 230 V AC coil voltage. Additionally, it features a test button for manual operation, facilitating diagnostics and easy control.
