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.

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.

They say that whoever works – makes mistakes. Well so do we! We have an old circuit board that we rest from unsuccessful projects or are simply a bug. There has excess PCBs of prototype products or serial products that are no longer manufactured. You will find everything, not necessarily functional 🙂

Use these chips to practice soldering on them, like a keychain or decoration for the wall. Give them to a friend. Make your next project on them. Let your imagination run wild 🙂

Note: Do not take these printed circuit boards as functional. We can not offer technical support for them. Some of them may have a number of brazed components.

Classic NPN SMD transistor.

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

ESP8266 is an IC that delivers a true revolution in the world of makers, especially in the world of IoT (Internet of Things). This is a complete 32-bit SoC (System on Chip) with built-in flash memory, frame and EEPROM which can even be programmed directly from the Arduino interface, without the need for additional micro-controller. With all this, the most important point is that in itself has a built-in WiFi (AP, STA, AP + STA), all that for “little money”.

ESP8266 in this form (ESP-12) is suitable for direct soldering to a printed circuit board as an SMD component or directly solder the wires since the pin has its holes. It also comes with a PCB trace antenna.

Note: ESP8266 is an IC that works at 3.3V! Connecting directly to 5V, or track Arduino or Croduino plate will destroy it! Use logic level converter.

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

5mm RGB LEDs in a classic through-hole version with 4 pins. Each one representing one color (+), while the longest pin being a common cathode (common negative) for all three colors.

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.

LM 7805 is often used 5V linear regulator, this one is in the THT version.

Well known and popular 8-bit Atmel microcontroller which is used on the majority of modern Arduino boards as well as on Dasduino. This one is the SMD version, just as the one on Dasduino, which is used for soldering on PCBs and for usage in projects.

5mm diffused LED diodes are great for experimenting and trying new things, which is why they are included in our Dasduino Beginner Kit (DBK)!

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.

Large pushbutton will often be more practical than the small one (classic pushbutton). With dimensions of 12mm x 12mm it can be pushed in the breadboard, but it is also suitable for ordinary drill boards.

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