Description

Pro Mini 328P – compatible with Arduino

Universal module with ATmega328P microcontroller. Can be used in many microprocessor projects. Circuit compatible with Arduino PRO MINI 3.3V 16MHz project. The microcontroller has a bootloader preloaded, so all you need to program it is a UART programmer, such as one for 5zł.

You are interested in electronics, or programming? If so, then Arduino is just for you, as it combines these two worlds! Thanks to microprocessors, you will realize various projects!

We used the product to build projects:

• Long distance temperature controller

Product features

• The Pro Mini, like the UNO, is based on a popular microcontroller
• It has an Atmega328P microcontroller.
• The board contains an ATmega328 chip, equipped with 14 digital I/Os, 6 of which support PWM signals (e.g., for servo control), as well as 8 analog inputs (for voltage measurement), but can also act as additional digital pins (a total of 22 digital I/Os).
• Works with voltages of 3.3V.
• It is clocked with a 16 MHz clock signal.
• Switch for manual reset
• This version has no soldered connectors – so the board can keep its small size.

Technical data

• VCC supply voltage: 3,3V
• RAW supply voltage: from 4 to 12V
• Microcontroller: ATmega328P – 16 MHz
• Ports – I/O pins: 14
• Number of analog inputs: 8
• Number of PWM outputs: 6
• Serial interfaces: UART, SPI, I2C
• External and internal interrupts
• Protection against the flow of too much current
• Module made on 0.8 mm thick laminate
• Weight less than 2 g.
• Pin spacing 2.54mm (can be mounted in contact boards)
• Dimensions: 33 x 18 mm
• 32kB flash memory
• 1kB EEPROM
• 1kB SRAM
• 2 8bit timers/counters
• 1 timer/counter 16bit

Additional information

• Power supply
  • If the supply voltage is higher than 3.3V, it should be connected to the RAW pin, which is connected to the stabilizer (then the voltage is 7-10V).
  • VCC is connected directly to the pins of the microcontroller, connecting a voltage higher than 5V can permanently damage the chip.
• Inputs/outputs
  • Arduino Pro has 14 digital input/output (I/O) leads.
  • Each pin allows a maximum current draw of 40mA, allowing direct connection of LEDs with resistors and control of other ICs.
  • In addition to standard I/O, some leads also have special functions.
• Programming
  • Software development and uploading is enabled by a free environment provided by the manufacturer.
  • Arduino Pro does not have a chip that controls the USB interface. Therefore, a UART<->USB adapter is required for programming.
  • For programming, you can use PL2303 Programmer or aVR ISP programmer.
