++By default, programming the RA4M1 microcontroller is handled through the ESP32-S3, which works as a USB bridge. This configuration allows uploading via USB-C without requiring additional setup. +
+ ++The board features a USB-C port for both powering and programming. It also supports serial communication and works as the main development interface. +
+ +Warning: Do not exceed 5 V on the USB-C port to avoid hardware damage.
++The RA4M1 microcontroller provides a 12-bit DAC connected to the A0 pin. It can generate analog output signals such as variable voltage levels or waveforms for audio and signal testing applications. +
+ ++The onboard QWIIC connector (SM04B-SRSS-TB) allows plug-and-play I2C communication with 3.3 V QWIIC-compatible modules. It is connected to a secondary I2C bus powered by the onboard 3.3 V regulator. +
+ ++The main I2C bus is also accessible on A4 (SDA) and A5 (SCL) pins. Avoid using A4/A5 as analog inputs while I2C communication is active. +
+ ++ For more technical information, schematics, and configuration details, refer to the official UNO R4 WiFi documentation: + + UNO R4 WiFi Official Documentation [1] + +
+Note: Operating conditions reflect general limits for the main board and consider reasonable usage of connected peripherals. Component-specific ratings may vary.
++The UNO R4 WiFi supports power inputs via USB-C or the VIN pin (DC barrel jack). A buck converter (ISL854102FRZ) regulates VIN input (6-24 V) down to 5 V. USB input is internally dropped to ~4.7 V due to a Schottky diode. +
+ +A 3.3 V linear regulator (SGM2205-3.3XKC3G/TR) supplies the ESP32-S3 and other 3.3 V peripherals. + +### Pin Voltage and Current + +- **Logic Levels**: RA4M1 operates at 5 V / ESP32-S3 at 3.3 V +- **Current per GPIO**: Up to 8 mA +- **Important**: Do not apply 5 V signals to ESP32-S3 pins + +Always use external power supplies for high-current loads like servos or DC motors. + ++ For more technical information, schematics, and configuration details, refer to the official UNO R4 WiFi documentation: + + UNO R4 WiFi Official Documentation [1] + +
++The Starter Kit R4 supports multiple powering options via the Arduino UNO R4 WiFi board. When connecting additional peripherals, ensure they are within the supported voltage and current limits.
+ +-VIN / Barrel Jack: Accepts 6-24 VDC input, regulated to 5 V using the onboard buck converter (ISL854102FRZ). Recommended for projects requiring higher or isolated input voltage sources.
+ +Note: A 9 V battery snap connector is included in the kit for use with a 9 V battery as a power source if desired. The 9 V battery is not included and must be purchased separately.
+USB-C Connector: Provides 5 V directly from the USB host. Actual voltage seen by the board is slightly reduced due to a Schottky diode (~4.7 V). Suitable for desktop or classroom use.
+-5 V Pin: Provides regulated 5 V output when the board is powered via USB or VIN. Use with caution and avoid connecting high-current loads (e.g., motors) directly to this pin.
+ +Warning: Exceeding the voltage or current ratings of the board or connected components may result in damage or unsafe operation. Always check the specifications of peripherals before connecting them.
