Although many do not know, there is a camera that can work with Arduino / Croduino. It is a CMOS camera, with VGA quality images that are connected to Croduino via I2C. Now it’s your turn to think of the application! Maybe combine with a motion sensor that could be activated if you someone entered the room?

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.

18650 battery holder allows easy use of lithium batteries in 18650 packaging. Otherwise, soldering these types of batteries is not recommended because the high temperature makes them lose their capacity. If you do not have a spot welding machine, we recommend that you get this kind of battery holder and you won’t have any problems with the loss of capacity, and it will allow you to use the batteries easily.

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.

This small AC-DC power supply is a simple solution to supply Dasduino or other small devices that run on 5V. It is simple, give it an AC voltage of 230V from the socket, and it outputs 5V with a maximum of 700mA, which is 3.5W. Furthermore, the power plug itself is really small and will fit in any case.

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

Vibration sensor SW-18020 is actually a switch that reacts (connects) to vibration, ie. moves. Thus, when a force acts on the sensor, it is connected, and when the force does not work, it is not connected.

e-radionica.com has created a module with an LM393 voltage comparator using this sensor. Check it out here.

 • Dimensions: 4.5mm diameter, 10mm high

We all know these Mini DC motors, especially if you ever took apart any kind of toy. They’re everywhere, now and on Soldered as well. You can use it to make something useful or just reminisce about the times when you were younger.

A phototransistor is a component that is able to detect light. This phototransistor is special because (due to their dark lenses) it detects infrared (IR) light better than the other. Therefore, it is practical for fire detection, sunlight etc.

Soldered has created a module with an LM393 voltage comparator using this sensor. Check it out here.

NEMA17 is a smaller stepper motor with high precision. Often we find it in 3D printers and small CNC machines since it has sufficient power to move small items. You will also use it in the 3D printer, CNC, robot or for the accurate control of anything which turns or moves.

We recommend the A4988 stepper motor driver.

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.

AMS1117-3.3V is a linear voltage regulator that provides an output voltage of 3.3V. It comes in a SOT-223 SMD packaging. More details, as always, in the datasheet.

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 🙂

Relay is a device with enables switching greater loads – ones that require more voltage/current. These relays can be found in our relays breakouts. It has NO and NC pins.

• Current needed for activation (current of Dasduino): 20mA
• Coil voltage: 5V
• Max. DC: 30V, 10A
• Max. AC: 250V, 10A

Gas sensor MQ7 detects the presence of Carbon Monoxide (CO) in the air. The best results are given when alcohol is in liquid form, however, it still does an amazing job when measuring in gas form. It needs a bit of time to warm up in order to work correctly.
