New NanoboyR4 Minima

          
           
 


New NanoboyR4 Minima features:

1.  Hardware compatibility with NANO form factor: The NanoboyR4 Minima maintains the same form factor, pinout, and 5 V operating voltage.  It's a drop-in replacement of its predecessor, the Arduino NANO. This ensures a seamless transition for existing projects, leveraging the extensive and unique ecosystem already established for the Arduino NANO.

2.  Expanded memory and faster clock: Prepare for more precise calculations and the ability to handle complex projects with ease. The Nanoboy-R4 Minima boasts increased memory and a faster clock speed, empowering you to tackle demanding tasks effortlessly.

3.  Extra on-board peripherals: The Nanoboy-R4 Minima introduces a range of on-board peripherals, including a 12-bit DAC, CAN BUS, OP AMP and QWIIC interface for external 3.3V sensors. These additional components provide you with expanded capabilities and flexibility in your designs.

4.  SWD connector: Debugging is a critical aspect of any project. Simply connect an external debugger to the Nanoboy-R4 Minima and effortlessly monitor the inner workings of your system. Stay in control and gain valuable insights.

5.  HID support: The Nanoboy-R4 Minima comes with built-in HID (Human Interface Device) support, enabling it to simulate a mouse or keyboard when connected to a computer via a USB cable. This convenient feature makes it a breeze to send keystrokes and mouse movements to a computer, enhancing usability and functionality.

6.  Size: 1.7" X 0.7" or 43.18mm X 17.78mm.

Get ready to unlock a world of possibilities with the Nanoboy-R4 Minima. Its exceptional features and enhanced capabilities make it the perfect companion for your innovative ventures.

The NanoboyR4 is not shown on the Arduino UNO R4 board list, you can use it as an Arduino UNO R4 Minima board.  It can do whatever an Arduino UNO R4 Minima can do.

The NanoboyR4 board is pre-loaded with a test sketch and it will blink all output pins including the user LED at GPIO13.
Before soldering all male headers make sure that the NanoboyR4 board can blink the GPIO13 LED with your Arduino IDE.
If it can't, troubleshoot the problem first before going further.
If you can't Blink-A-LED before soldering, you won't be able to Blink-A-LED after soldering.

NanoboyR4 assembly Instructions are similar to the SmallPICO assembly instructions.

 
    The 2.2" TFT dsplay is a 3.3V device. A logic level shifter is needed for the Nanoboy-R4, a 5V device, to drive a 2.2" TFT display.
