About this item
- What is the Mega 2560 R3+: The PTSolns Mega 2560 R3+ is a versatile microcontroller development board based on the ATmega2560, featuring an 8-bit processor running at 16 MHz. With 54 digital I/O pins (15 supporting PWM), 16 analog inputs, 4 hardware serial ports, and 256 KB of flash memory, this board is ideal for complex projects involving robotics, automation, sensor networks, and data acquisition. Its modern USB-C interface and compatibility with Arduino shields make it an excellent choice for hobbyists, educators, and professionals alike.
- Easy to start: The Mega 2560 R3+ supports popular development environments, including PTSolns IDE, Arduino IDE and PlatformIO. Its compatibility with the Arduino Mega 2560 platform allows users to access a vast collection of libraries, tutorials, and example sketches. Simply connect the board to your computer, select "Arduino Mega or Mega 2560" in the Arduino IDE, and start programming. Additional technical information and supporting resources can be found through our "PTSolns Documentation Repository".
- What’s Included: Each package includes one (1) PTSolns Mega 2560 R3+, fully assembled. Bootloader and Getting Started sketch burned and uploaded. USB cable not included. Use a USB-C cable that supports data transfer, as some cables only provide power.
- PTSolns IDE: Use the "PTSolns IDE" desktop application to program this, and many other, microcontroller development boards. Free to download, many example sketches, 8500+ 3rd party libraries, built-in CH340 support.
- PTSolns Customer Support & Resources: We’re here to help. Contact PTSolns support for technical assistance or product questions. Every PTSolns product is backed by our comprehensive Documentation Repository, featuring datasheets, schematics, 3D models, Fritzing files, software libraries, tutorials, and more. All resources are freely available to help you get the most from your projects.
Product Description
The PTSolns Mega 2560 R3+, based on the ATmega2560, is a popular microcontroller development board with additional unique features. The Mega 2560 R3+ continues to be compatible with a range of standard shields, offering the standard pin numbering and layout. A standout feature is the onboard QWIIC connector, which provides a shifted 3.3 V I2C bus, making it convenient to connect many common sensors and modules that operate on 3.3 V logic. There is no need for extra external components; all the logic level shifting between 5 V and 3.3 V on the I2C bus is done automatically onboard.
The Mega 2560 R3+ replaces the previous bulky port with a modern USB-C port, while the standard power barrel jack remains onboard. The board has a streamlined layout of components, including a clean grouping of the onboard LEDs (ON, 13, TX, RX). Furthermore, the Mega 2560 R3+ allows for a larger current draw on the 3.3 V pin with a rated maximum of 0.8A. This lets the user manage their project’s power budget more easily by allowing a larger current draw.
The Mega 2560 R3+ comes with a pre-installed out-of-the-box ready set of tests. This gets simple projects started quickly and allows for testing the proper function of the board. A large active online community supports this microcontroller and its programming using PTSolns IDE or the Arduino IDE software.
This Plus version offers all of the features users come to learn and expect, and adds additional ones that make this board stand out.
All Mega 2560 R3+ boards are individually inspected and marked with a quality control sticker (either on the PCB, or on the packaging).
This product, along with all of the PTSolns products, comes with a detailed datasheet, and other supporting material. Please view our "PTSolns Documentation Repository" to access these documents.

Ready-to-use out-of-the-box ... Fully assembled, bootloader burned, and "GetStarted" sketch uploaded!
The Mega 2560 R3+ microcontroller development board comes ready-to-use out-of-the-box. What does that mean exactly?
- Fully assembled: The Mega 2560 R3+ is fully assembled with female headers soldered in place. With the modern USB-C Port onboard, getting started is as easy as plugging it in.
- Experiment ready: The Mega 2560 R3+ has bootloader burned, and our custom "GetStarted" sketch has been uploaded.
Get tinkering right away with the five tests uploaded in our custom "GetStarted" sketch (NOTE below). These tests include:
- Test 1: Onboard LED (Pin 13) Blink Unique Pattern. Observe a blinking pattern on the onboard LED.
- Test 2: Onboard LED (Pin 13) Blink Reset Pattern. Observe a different short blinking pattern upon pressing RST.
- Test 3: I2C Scanner (Image with the circled "3" above). Connect a peripheral via I2C and automatically scan its address. View the results in Serial Monitor on baud 9600 (See NOTE below).
- Test 4: Pin 9 Fade (Image with the circled "2" above). Connect an external LED and a resistor from Pin 9 to ground and observe the classic "Fade" example.
- Test 5: Analog A0 Read. Connect a wire to the A0 Pin and observe the readout on the Serial Monitor on baud 9600 (See NOTE below).
These tests are explained in detail in the User Manual of the Mega 2560 R3+.
NOTE: Please ensure you have the CH340 driver installed (Only required once - Likely you already have it). Details on how to install this common driver can be found in the Datasheet for the Mega 2560 R3+.
