Whether you are a beginner or an experienced electronics enthusiast this powerful and reliable development board will make your projects even more exciting. It also has additional onboard peripherals such as 12-bit DAC, CAN bus, operational amplifier, support for 24V input voltage range, support for SWD debugging and HID functions. The R4 Minima is the perfect partner for your creative exploration.

Parameter:

1. UN0 shape compatibility: The R4 Minima retains the same shape, pin arrangement and 5V operating voltage as its predecessor, the R3. This ensures a seamless transition of existing expansion boards and projects, taking advantage of the extensive and unique ecosystem already established for UN0.

2. Expanded memory and faster clock: Ready for more accurate calculations and the ability to handle complex projects with ease. The R4 Minima has more memory and faster clock speed, making it easy for you to handle demanding tasks.

3. Additional on-board peripherals: The R4 Minima introduces a range of on-board peripherals, including 12-bit Dacs, a CAN bus, and operational amplifiers. The components of these attachments give you scalability and design flexibility.

4. Extended 24V tolerance: The R4 Minima now supports a wider range of input voltages, allowing power supplies up to 24V. This makes it possible to seamlessly integrate motors. LED strips, and other actuators, simplifying your projects by using a single power source.

5. SWD Connectors: Debugging is a key aspect of any project. Simply connect an external debugger to the R4 Minima to easily monitor the inner workings of your system. Stay in control and gain valuable insights.
