Backward hardware compatibility - the R4 maintains the same pin layout and 5V operating voltage as the R3. This means existing expansion boards and projects can easily be ported to new boards. New built-in peripherals - the R4 board features several exciting new peripherals, including a 12-bit DAC, CAN bus, operational amplifier, and SWD port. These recently added peripherals have expanded developers' possibilities, enabling more advanced projects. More memory and faster clock - With increased storage capacity (16x) and clock speed (3x), the R4 Minima can perform more precise calculations and handle complex projects. This allows manufacturers to build more complex and advanced projects. Human-machine interface communication via USB-C - the R4 can be used as a mouse or keyboard when connected to its USB-C port, making it easy for manufacturers to create a fast and cool interface. Wide voltage range and electrical stability - the R4 board can be powered up to 24V thanks to its improved thermal design. Multiple protective measures are implemented in the circuit design to reduce the risk of damage to the board or computer caused by connection errors from inexperienced users. Additionally, the RA4M1 microcontroller on the R4 Minima has overcurrent protection to prevent issues from occurring. Capacitive touch support - the RA4M1 microcontroller used on the R4 board supports built-in capacitive touch. Equipped with WiFi and Bluetooth connectivity - the R4 WiFi includes an ESP32-S3-MINI coprocessor that enhances the functionality of the RA4M1 microcontroller. With WiFi and Bluetooth connectivity, developers can easily connect to the internet and create IoT projects. Built-in 12x8 LED matrix - the R4 WiFi board is equipped with a bright 12x8 red LED matrix (total of 96 pixels). This feature is ideal for projects using animation or drawing sensor data without needing additional hardware. I2C contact - the R4 WiFi board is equipped with an industry-standard Qwiic I2C contact for simple and fast prototyping. Through an I2C connection, various compatible modules can be connected, allowing creators to easily build customized projects and expand the functionality of the R4 WiFi. Error diagnostics - the R4 WiFi board has an built-in error detection mechanism that can identify operations that might cause the board to crash, such as division by zero. When an error is detected, the board will output a detailed error description and cause on the serial monitor. Supports battery operation - the R4 has additional pins that can turn off the main microcontroller while maintaining internal power supply with an external battery function (for UNOR4 Minima) Powerful and cost-effective - the R4 Minima offers impressive performance at a competitive price. This board is an especially cost-effective choice and reinforces our commitment to promoting advanced technology.
