Product description

The board is a microcontroller development board with an ATmega328P that can be programmed using the Arduino IDE and is ready for use in prototypes, educational projects, or hobby applications. The core of the system is the chip in a DIP package, which operates at a clock frequency of 16 MHz and executes code from the 32 KB flash memory.

Programming is carried out via a USB-B cable, which also powers the board during development. For standalone operation, an external power source supplying between 7 and 12 V via the barrel jack powers a voltage regulator that generates a stable 5 V operating voltage. The board provides up to 500 mA at the 5 V output and up to 50 mA at the 3.3 V output, allowing external sensors and small modules to be powered as well.

The 14 digital pins are used to control actuators, switches, and displays, 6 of which can additionally output pulse-width modulation (PWM) for dimming LEDs or controlling small motors, for example. The 6 analog inputs capture continuous readings from sensors such as temperature or light sensors. A built-in LED on pin 13 enables initial tests without external components.

The memory is divided into three sections: 2 KB of SRAM as volatile working memory during program execution, 1 KB of EEPROM for data that remains stored even after power loss, and 32 KB of flash memory for the program code. The reset button restarts the running program. Commissioning requires a computer with the Arduino IDE and a USB-B cable to connect to the board. An external power supply is required if the board is to be operated independently of the computer.

Safety information

The development board is not intended for installation in the household electrical circuit and is intended exclusively for building prototypes and for testing and development purposes. Work on or near electrical installations must be carried out by qualified electricians. When using an external power source, ensure that the permissible input voltage of 7 to 12 V is observed.
