MQ7 gas sensor - CO(carbon monoxide)
MQ7 gas sensor - CO(carbon monoxide)

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.

MQ6 gas sensor - LPG, propane
MQ6 gas sensor - LPG, propane

Gas sensor MQ6 detects the presence of different gases such as LPG (Liquid Petroleum Gas), propane, isobutane, LNG (Liquid Natural Gas). The best results are given when gas is in liquid form, however, since situations like this are rare, it does its job pretty well when in gas form, too. It needs a bit of time to warm up in order to work correctly.

 

MQ4 gas sensor- natural gas, methane
MQ4 gas sensor- natural gas, methane

MQ-4 methane gas sensor registers the presence and concentration of natural gas and methane (CH4). The best results are given when gas is in liquid form, however, since situations like this are rare, it does its job pretty well when in gas form, too. It needs a bit of time to warm up in order to work correctly.

3x LED 7-segment display red, common cathode
3x LED 7-segment display red, common cathode

A 7-segment display is classical, often used and already familiar component. Size of a digit on the display is 0.56inch and the light it transmits is red. The display has a common cathode.

 

1x LED 7-segment display RED, common cathode
1x LED 7-segment display RED, common cathode

A 7-segment display is a classic, often used and already familiar component. The size of the digit on the display is 0.56inch and the light it transmits is red. The display has a common cathode.

2x Alligator to banana cable
2x Alligator to banana cable

If you use some laboratory equipment such as power source, signal generators or, in most cases, multimeters – you’ll find this cable very practical. It has 2 banana connectors – on one end so you could connect it to mentioned devices and on another end to connect it to alligator connector which allows you to connect to almost anything!

Female DC connector with terminal
Female DC connector with terminal

Connecting to other devices and controllers from improvised power sources becomes truly simple with this terminal. Just use a screwdriver to tighten your wires to the terminal and you’re ready!

 

Male DC connector with terminal
Male DC connector with terminal

Connecting to many other devices and controllers from improvised power sources becomes truly simple with this terminal. Just use a screwdriver to tighten your wires to the terminal and you’re ready!

 

Step-up module 150W
Step-up module 150W

Smaller booster (step-up) module. It increases input voltage to the desired level.

 

CR2032 battery holder
CR2032 battery holder

A through-hole holder for CR2032 3V battery which you can find on watches,  RTCs, toys, motherboard and other electronics.

 

BR2032 batteries are also suitable for this holder, but we do have one more battery type for you – CR2032 battery.

Crystal (oscilator) 16MHz HC49US
Crystal (oscilator) 16MHz HC49US

Crystal (oscillator) with a frequency of 16MHz.

 

CR1220 battery holder
CR1220 battery holder

SMD Battery Holder for CR1220 3V battery, just like the one on our Croduino Damba.

USB SMD mini-B connector
USB SMD mini-B connector

USB mini-b female connector for a printed circuit board (PCB). It’s identical to the one used on Croduino Basic.

DC Motor Driver Dual H-Bridge L298N
DC Motor Driver Dual H-Bridge L298N

H bridge supports an exchange of polarities on its outputs and therefore enables control of motor spins in both directions in a very simple way. It can also direct other devices that for certain usage require the exchange of polarities on their inputs.

 

13.56MHz RFID tag
13.56MHz RFID tag

Additional passive RFID tag to use with our RFID scanners. Very practical as a pendant for keys and based on Philips Milfare IC.

 

1N4148 diode
1N4148 diode

This is a pretty ordinary signal diode 1N4148. It is used for signals up to 200mA of current.

 

1N4007 diode
1N4007 diode

Ordinary and well-known rectifier diode 1N4007. It’s often used for rectification of voltage, protection from the wrong polarity, different projects with breadboard etc.

Max. voltage that this diode can endure is 1000V and max. current it can carry out is 30A.

 

Generic N-channel MOSFET DPAK
Generic N-channel MOSFET DPAK

MOSFET transistor N-channel has ideal characteristics that allow it to connect to Croduino/Arduino. With this transistor, you’re able to control devices that need big amounts of current or voltage – all of that via a microcontroller.



Rotary encoder 20mm with pushbutton
Rotary encoder 20mm with pushbutton

A rotary encoder can be rotated endlessly – it has no end. That’s the main difference between it and the potentiometer and the reason why it’s more suitable for usage in certain applications. Its output (rotation outcome) is written in gray code, therefore you’ll need a microcontroller in order to use it.

 

It also has inbuilt pushbutton which makes it suitable for different selections.
