 The ESP32 module and the Renesas RA4M1-chip are part of a sophisticated USB-Serial system that is highly flexible and adaptive to allow for HID features while still keeping the ability to program both the main MCU, and the ESP32, if you so wish (although this is an advanced option and requires some hacking).

+The board can be powered via the VIN pin, supporting a range between 6-24 V. The VIN pin is also connected to the DC-jack (barrel plug connector).
 
 When powered via the VIN pin, you are using the onboard regulator to bring down the voltage to 5V, which means that the 5 V pin can provide up to 1.2 A. Keep in mind that this voltage regulator also powers the rest of the circuit board, including the MCU, LEDs among other components.

 The UNO R4 WiFi features a Qwiic/STEMMA connector that you can use to connect modules, often allowing you to daisy chain several modules and control all of them through a single connector.
 
-Qwiic or STEMMA are both names for a type of connector developed by SparkFun and Adafruit respectively, that bundles the I2C pins of a development board and breakout modules. What this means is that if you have a development board (such as for example the Arduino UNO R4 WiFi) and a breakout module, and both have a Qwiic or STEMMA connector, you can hook them up together and with absolutely minimal wiring you can quickly create multi-faceted projects.
