Description
Module with AVR ATmega328 microcontroller is equipped with 28 KB of Flash memory, 18 digital pins, analog inputs and 8 PWM channels. On board is a microUSB connector, thanks to which the system can be programmed via the Arduino IDE. This version works with a voltage of 5 V. In our offer is also a module operating with a voltage of 3,3 V.

The collaboration with Arduino
The device can be programmed via the Arduino environment, however, due to the small size of the board, there are some differences:
- Pins 2 and 7 are unavailable due to their use in USB communication.
- The board is working with a supply voltage of 5 V and a clock frequency of 16 MHz, so not all sample programs will work properly..
- Built-in voltage regulator 5 V, has a power delivery of up to 150 mA.
- The board doesn't have the FTDI chip, to connect the serial interface, you must use an external cable or converter. The USB connector is only used for uploading the program.
- The bootloader takes 4 KB of Flash memory, the user has at his/her disposal 28,672 b.
