KW12-3 is a standard microswitch – it’s activated by the external force on the lever. Releasing the force we deactivate it. This system is very quick and practical, it allows dynamic changes in the switch. The lever itself is able to rotate – it has a little wheel on the top. Microswitches like these are used in PC mouses, automobile industry, communication devices, microwave oven doors etc.

These magnetic door switch sensors are already seen, if not – then in old movies for sure where they were used as anti-theft devices, ie. alarm systems. In fact, it is a magnet and the reed switch inside a pair. When they are close to each other (recommended 13mm or less), reed switch closes. Connect it to Croduino / Arduino as an ordinary switch use the detection of open doors, windows, drawers, cupboards etc.

• Voltage: max. 200V, best used 5V Croduino/Arduino
• Max reed power: 100mA
• Max detection distance: 15mm, 13mm recommended
• Dimensions: 29 x 14 x 9mm
• Cable length: 30cm

25x Capacitor 1206 10uF.

Classic capacitor 0603 100nF 50V, tolerance 10%. Most often used as a decoupling capacitor.
It comes in a pack of 50 pieces.

Resistor 0603 10k ohm with precision of 5%.

Resistor 0603 1k ohm with precision of 5%.

Optocoupler 4N35 is a device that electrically (by light, not by electricity) separates the two parts of the circuit. That means, if a short circuit occurs  on one part of the circuit or any kind of other error that causes malfunction of components, there won’t be any malfunctions to the second part of the circuit because there is no way (since they separated by light) to transfer the error.

To sum it up, this optocoupler is very common and generally, it can be used for all applications.

Come on, everyone knows what the NE555 is! It is unlikely that we could make anything in our store without it, since it is inevitable in any kind of education, and is also able to solve the “time” problems in any type of assembly. It is a timer and can be used to create a pulse oscillator, delays …

The ceramic antenna at a frequency of 1575.42MHz corresponding GPS. Ideal with our SIM808 breakout.

Reed switch is a switch that is activated within the range of the magnetic field. Within its glass capsule, it has two metal wires that will move when they are near the magnet and thus “activate” switch.

MMBT4403 is the PNP transistor of general use in SMT SOT-23 package. More details in the datasheet.

Potentiometer of variable resistance of 10k which can be used on an experimental board, but it can also be installed in the housing. They can be used for various types of control, eg. Setting how the brightness of LEDs.

LM358 is probably the best known and most frequently used operational amplifier. One pack contains two op-AMPs, but one can be used as a buffer, and one to increase its voltage. It is very convenient and easy to use. Also, this is a dual supply op-amp, which means you can turn up positive and negative voltages.

The AMS1117-3.3V is a linear voltage regulator designed to provide a stable 3.3V output from a wide input voltage range of 4.4V to 12V. This component is perfect for powering sensitive electronics, microcontrollers like Arduino boards, and various IoT devices that require a consistent 3.3V supply. Its design ensures efficient power conversion, making it a great piece for both hobbyist and professional electronic projects.

Packaged in a compact SOT-223 SMD form factor, the AMS1117-3.3V is suitable for space-constrained applications. It delivers a maximum output current of 1A, providing ample power for most low-power digital circuits and sensors. The simplicity of its operation, combined with its high performance, makes it an excellent choice for designers looking for an effective voltage regulation solution.

Our AMS1117-3.3V regulator comes with technical support and a 2-year warranty. Whether you’re building a new prototype, repairing existing equipment, or integrating it into a complex system, this voltage regulator provides the stability and performance you need. Detailed specifications and application notes are available in the datasheet for seamless integration.

25x 330ohm resistor (for LEDs)

Classic NPN SMD transistor.

Screw terminal for PCBs with a width of 3.5mm pin with two contacts.

Micro-USB SMD connector for soldering to the printed circuit board. The same as it’s used to Croduino Nova, CP2102 USB to UART adapter.

Commonly used in a ceramic capacitor performance – Capacitor 100nF always come in handy 🙂
