• All connections soldered in a standard 0.1-inch pitch, header pins can be installed as desired

Product Description

A compact microcontroller board with an ATmega328P is suitable for prototypes where space requirements or compatibility with standard breadboards are crucial. Compared with larger boards, its approximately 4.5-centimeter length saves considerable space without sacrificing the full complement of 14 digital and 8 analog inputs.

The ATmega328P is powered via the USB interface or an external power supply from 6 volts. The CH340 chip converts the USB connection into a serial data stream, allowing the board to be programmed and communicate directly with the computer without additional hardware. The unsoldered configuration allows the header pins to be soldered according to your requirements or omitted entirely if wire connections are preferred.

The board is suitable for applications such as environmental sensors in space-constrained enclosures, simple data loggers for field use, controls for small robots, or as an interface between sensors and computers. Development environments such as the Arduino IDE recognize the board directly and allow sketches to be uploaded immediately.

Requirements include installing the header pins as desired and using connecting wires or plug-in connections for the sensors and actuators. Power is supplied either via USB or external sources between 6 and 20 volts; when operating with a battery or power adapter, the polarity must be observed to prevent damage.

Safety Notice

This board is intended exclusively for building prototypes and for testing and development purposes, and is not designed for installation in household electrical circuits. When using an external power supply, ensure correct polarity and compliance with the specified voltage. Work on or near electrical installations must be carried out by qualified electricians; if in doubt, consult a qualified electrician before commissioning.
