ARDUINO PRO MINI 328 5V/16MHz

Arduino pro mini 328 is a miniature version of Arduino for breadboarding projects of varying technical complexity. The board is intended for radio amateurs who are not the first time using the Arduino platform. Based on the ATmega328 microcontroller, this Arduino pro mini board is an improved version of the Arduino pro mini 168 platform. The board operates at a voltage of 5 V and a frequency of 16 MHz.

The Arduino pro mini 328 board has 14 digital and 6 analog pins. If you need to connect external devices, you can use the I2C serial interface, which is connected via analog pins A6 (SDA) and A5 (SCL).

Also, 2 indicators are designed on the module. One LED indicates that voltage is applied, and the other indicator lights up when logic voltage is applied to digital pin 13.

You can supply voltage to the board module using an external power supply or a converter. The GND, VCC, and RAW pins are used to supply voltage to the board. The GND pin serves as ground, and the VCC pin is supplied with a nominal 5V power supply. This pin must be supplied with regulated power, since the voltage from this pin is supplied directly to the microcontroller. If you need to power the board from an unregulated power source, you must connect to the RAW pin. When power is applied to this pin, the voltage passes through the stabilizer, and after stabilization, the voltage is transmitted to the microcontroller.

The module is sold unassembled. The module kit includes: a board and contact extensions that can be mounted on the outputs by soldering.
