## Description

270-point solderless breadboard, ideal for rapid testing of circuits without soldering. 2.54 mm pitch for common modules and microcontrollers, includes a voltage regulator for simple power supply, modular construction expandable by joining with other boards, durable material for repeated use in the lab or at home.
SYB-46 is a solderless prototyping board with 270 connection points, designed for hobbyists, students, and professionals who want to test and build electronic circuits quickly and efficiently. With dimensions of 23x12 cm, the board provides enough working space on any workbench or desk without taking up too much room.
The material withstands temperatures of up to 105 degrees Celsius, making it suitable for intensive prototyping sessions. The 1W power dissipation allows use in a wide range of applications with low- to medium-power components.
Among the main features are: the solderless construction that allows components to be inserted and removed without soldering, the 270 connection points arranged for clear and fast wiring, the integrated voltage regulator that simplifies powering projects, compatibility with Arduino, STM32, ESP32, and any other microcontroller with standard 2.54 mm pins, as well as the possibility of customization according to project needs.
The board is modular and can be expanded by joining additional SYB-46 boards.
This board is ideal for experimentation, learning, and circuit testing before moving on to a permanent solution.

Usage:
Make sure the board is clean and that there are no leftover residues or components from previous sessions.
Connect the power supply to the board’s power pins, using the integrated voltage regulator to set the desired voltage.
Insert electronic components (resistors, capacitors, LEDs, modules, etc.) into the desired points on the board, pressing gently until they make firm contact.
Connect jumper wires between components to build the desired circuit.
Connect the board to the chosen microcontroller (Arduino, ESP32, STM32, etc.) using standard 2.54 mm jumper wires.
Check the connections before powering the circuit to avoid short circuits.
Power the circuit and test its operation according to your project schematic.
After completing the tests, disconnect the power and carefully remove the components so they can be reused.
