JST (more precisely JST XH) connectors are today the most common connectors for rechargeable lithium batteries but are also used for many other applications where a fast, easy and convenient connection is required.
Banana connectors are quite standard connectors in electronic labs because they allow fast and firm connection.
This antenna is designed for 433MHz modules from our offer and improves their range even up to 300%. It works both as a receiver and as an emitter.
• Frequency range: 433MHz (+-6MHz)
• Amplification: 2.2dBi
• Impendance: 50ohm
• Maximum power: 30dBi
Male header at 90 degrees angle and pin spacing 2.54mm (0.1 ‘). 40-pin.
Comes in a pack of 5 pieces.
This lithium-ion battery is small, light and durable. Through standard JST 2mm female connector, it will yield 3.7V which will supply your projects for a whole day (and night!). Furthermore, the battery has an implemented protection system, which prevents high voltages ( prevents over-charging), undervoltage and short circuit. That way it protects the battery, increases its lifetime and protects you from possible accidents!
This small battery is practical for smartwatch projects or other projects where battery dimensions are crucial.
• Nominal voltage: 3.7V
• Capacity: 40mAh, 0.15Wh
• Dimensions: 24 x 8.5 x 3.5mm
• Standard JST-PH-2mm connector
DISCLAIMER: This battery has to be charged with a special charged that uses CC/CV principle. Li-ion batteries are dangerous! Read our tutorial (link in the top right corner) before use.
• Frequency: 32.768kHz

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.
Crystal (oscillator) is identical to one that uses a frequency of 8MHz, in HC49S (standard THT) packaging.
