The For UNO R4 maintains the same form factor, pinout, and 5V operating voltage as its predecessor, the R3. This ensures a seamless transition for existing expansion boards and projects, leveraging the extensive and unique ecosystem already established for the Arduino UNO. Expanded Memory and Faster Clocks: Get ready for more precise calculations and be able to handle complex projects with ease. For UNO R4, with larger memory and faster clock speeds, you can handle tough tasks with ease . Additional on-board peripherals: For UNO R4 introduces a range of on-board peripherals, including 12-bit DAC, CAN bus and operational amplifiers. These add-ons provide expanded functionality and flexibility for your designs. Extended 24V Tolerance: For UNO R4 now supports a wider input voltage range, allowing up to 24V power supply. This can be implemented with motors, LED strips Seamless integration with other actuators simplifies your projects by utilizing a single power supply. SWD Connector: Debugging is a key aspect of any project. Simply connect an external debugger to the R4 to easily monitor the inner workings of your system. Stay in control and gain valuable insights. HID Support: For UNO R4 has built-in HID (Human Interface Device) support, allowing it to emulate a mouse or keyboard when connected to a computer via a USB cable. This convenient feature makes sending keystrokes and mouse movements to the computer a simple and easy task. It's a breeze, thereby enhancing usability and functionality. Improved version features: 1. The DC power supply chip has been improved to use IC, and the interface has been extended to one more row to facilitate additional leads. 2. The main control board is fully compatible with the official functions. Due to different batches, the appearance, color, and printed words of the product may vary, which doe
