I. Appearance Rendering:
The Xiao An Pai-UNO-ET485 Arduino development board adopts the classic Arduino UNO form factor design, and the header also maintains the classic shape. It includes an Ethernet port, which is not found on other Xiao An Pai boards.
The main control module remains the Ai-M61-32S WiFi6 module, bringing out all available GPIOs for easy expansion.
II. Peripheral Description:
To maintain compatibility with the classic UNO form factor, the PCB cannot be expanded. Audio circuitry, screen driver circuitry, etc., cannot be integrated onto the board. However, this can be achieved using expansion boards.
III. Arduino IDE Compilation Screenshots
Other AI-thinker IDEs also support Arduino development. Many experienced developers have already written posts about setting up Arduino on the AI-thinker forum. You can search for them on the forum:
