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!

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.

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

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.

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

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.

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.

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.

78m05, often used 5V linear regulator in DPAK SMD package.

In a buzzer speaker, current is run through a coil of wire that produces a magnetic field. The flexible ferromagnetic disc is attracted to the coil when current is flowing through it and returns to a “rest” position when current is not flowing through the coil. The sound from the buzzer speaker is produced by moving a ferromagnetic disc in a similar way to a cone in a speaker.

The NRF24L01+ module 2.4GHz is an ultra-low power, 2Mbps RF transceiver for the 2.4GHz ISM band, ideal for reliable wireless communication in embedded systems. It features the enhanced ShockBurst™ protocol engine for automatic packet handling, address matching, and error correction. Its compact form factor and SPI interface make it perfect for Arduino, Raspberry Pi, and other microcontrollers, offering efficient, short-range wireless connectivity for battery-operated projects.
 
Operating on 3.3V (I/O pins 5V tolerant), the module includes a built-in 2.4GHz antenna and supports 250kbps, 1Mbps, and 2Mbps data rates. With 125 selectable channels, integrated power and low-noise amplifiers, and multi-channel capability, it ensures reliable communication in crowded environments and enables star-network topologies with up to six receivers.
 
Widely used in wireless peripherals, remote controls, home automation, and sensor networks, the NRF24L01+ is ideal for drones, data logging, and interactive projects. Pairing it with a 3.3V regulator ensures stable power for optimal RF performance. Add this module to enable robust, energy-efficient wireless communication in your next project.

The membrane keyboard is a system of 16 keys that are mutually connected and enable us more complex entry to Dasduino/Arduino. Using this keyboard, you can create whole systems of menus, data input, and adjustment of different parameters.

Set of male-female cables for connecting to various modules and components. You simply connect the module to the breadboard. It contains 40 cables of different colors, wire length is 15cm.

• Quantity: 40 cables
• Cable length: 15cm
• different colors for easier recognition

A male connector that is usually found on our power supplies. For use with our controllers and amplifiers.

A classic CR2032 3V battery, used in some watches or remote controllers.

CR1220 3V battery that we use in Croduino Damba.

Pushbutton is a small button that fits with the breadboard. It has two states: connected(ON – when the button is being pressed) and disconnected(OFF – when the button is not being pressed). It can be used, for example, as a switch. This pushbutton comes in Croduino for beginners set.

A photoresistor is a type of resistor that changes its resistance depending on a light that falls on it. They are super simple for making something that is needed to keep track of the amount of the light(for example, it turns the light on when it is dark).
