A high-density version of the Arduino Mega 2560 featuring 54 Digital I/O and 16 Analogue inputs in a compact footprint. Ideal for complex robotics and industrial automation, where space is at a premium.

Outgrowing your Uno but running out of space in your enclosure?

The Mega Pro Mini ATmega2560 is designed for engineers who need the massive I/O and memory capacity of the Arduino Mega 2560 but cannot afford the bulky footprint of the traditional board. By condensing the entire 54-pin architecture into a high-density layout, this board allows you to build industrial-grade controllers, 3D printer motherboards, and complex robotics without the "breadboard bulk."

The Professional Standard

In embedded systems, signal integrity is everything. This board is Probots™ ProSpec Grade, featuring high-quality decoupling capacitors and optimised trace routing to minimise electrical noise—critical when you are utilising all 16 analogue inputs simultaneously. Every batch is Probots™ Lab Verified in our Bangalore facility to ensure the CH340G USB-UART interface provides stable communication even during long-duration data logging sessions.

Specifications

  • Microcontroller: ATmega2560-16AU (8-bit AVR)

  • Clock Speed: 16 MHz

  • Flash Memory: 256 KB (8 KB used by bootloader)

  • SRAM: 8 KB

  • EEPROM: 4 KB

  • USB-UART: CH340G (Requires standard CH340 drivers)

  • Digital I/O Pins: 54 (of which 15 provide PWM output)

  • Analogue Input Pins: 16

  • DC Current per I/O Pin: 20 mA

  • Input Voltage (Recommended): 7-12V

  • USB Port: Micro-USB

Key Applications & Projects

  • 3D Printers & CNC: The compact size is perfect for custom RAMPS-style control boards.

  • Industrial PLC Emulation: With 54 pins, you can manage complex logic with dozens of relays and sensors.

  • Flight Controllers: Used in high-end DIY drones requiring multiple UARTs and PWM channels.

  • Home Automation Hubs: Large flash memory allows for complex web-server or touchscreen code.

Project Evolution

  • Past Projects (Prerequisites): If you’ve mastered the Arduino Uno but find yourself constantly using I/O expanders or running out of code space, this is your next step.

  • Feature Upgrade: This board unlocks four hardware Serial ports (UARTs), allowing you to talk to a GPS, a Bluetooth module, and a Nextion display simultaneously without using "SoftwareSerial."

  • Effort Level: Intermediate. It uses the same Arduino IDE code but requires careful pin mapping due to the high-density layout.

  • Hardware Needed: A Micro-USB data cable and a 7V-12V DC power supply for standalone operation.

Virtual Technician & Wiring

  • Driver Setup: Ensure you have the CH340 drivers installed. If the board isn't detected, check your USB cable; many are "Charge only" and lack data lines.

  • Power Rail: For stable operation of the ATmega2560, we recommend powering via the VIN pin with at least 7V if you are driving multiple sensors.

  • Probots™ Tech-Bridge ???? Tip: Need the specific pinout diagram for your CAD design? Our technical team has verified the dimensions and pin spacings for easy integration into your custom PCBs.

Accessories

  • Included: 1x Mega Pro Mini ATmega2560 Board, 2x 40-Pin Header Strips (Unsoldered).

  • Required Additional: Micro-USB Data Cable, 12V 2A Power Adapter (for high-load projects).

 

Helpful Tutorials & Resources

Frequently Asked Questions (FAQ)

  • Is this board 100% compatible with the Arduino IDE? Yes, simply select "Arduino Mega or Mega 2560" in the Tools > Board menu.
  • Does it use the same chip as the standard Mega? Yes, it uses the identical ATmega2560-16AU silicon.
  • What USB cable do I need? It uses a standard Micro-USB cable.
  • Can I use it with RAMPS 1.4? Not directly; the pin headers are in a different layout than the standard "Shield" format.
  • What is the logic level of this board? It operates at 5V logic.
  • How many PWM pins are available? There are 15 dedicated PWM pins.
  • How do I install the USB driver? Search for "CH340G driver" for your OS (Windows/Mac/Linux) and install it.
  • Does it include the pin headers? Yes, the headers are included in the package but are not soldered.
  • Can I power it via the USB port? Yes, for most basic projects, USB power is sufficient.
  • How many UART (Serial) ports does it have? It has 4 hardware UART ports.
  • Is it smaller than the Arduino Uno? Yes, it is significantly narrower and more compact.
  • Can it handle 24V input? No, the maximum recommended voltage on the VIN pin is 12V.
  • How much memory is available for my code? 256 KB, which is 8x more than the Arduino Uno.
  • Does it have an onboard power LED? Yes, a dedicated LED indicates power status.
  • Is it suitable for 3D printing applications? Yes, it is a favorite for compact 3D printer controllers.
  • What is the current limit per I/O pin? It is 20mA; exceeding this can damage the chip.
  • Can I use standard Arduino Mega Shields? No, the physical pin layout is modified for a smaller footprint.
  • Does it support I2C and SPI? Yes, it has dedicated hardware for both protocols.
  • What is the difference between this and the "Standard" Mega? The only difference is the physical size and the use of the CH340 USB chip instead of the Atmega16U2.
  • Is it reliable for 24/7 industrial use? When properly powered and shielded, the ATmega2560 is a highly reliable industrial workhorse.
