-The Arduino UNO R4 Minima is the first UNO board featuring a 32-bit microcontroller. With a new architecture based on the RA4M1 MCU from [Renesas](https://www.renesas.com/us/en), it is faster with its 48 MHz clock, has a lot more memory and brings new features such as a built-in RTC, DAC, HID support, CAN bus, JTAG connector and more.
-
-The board still features the classic barrel jack plug, with an improved voltage input range (6-24 V), but replaces the old USB connector with a USB-C® type connector. The UNO R4 Minima remains on a 5 V operating voltage, making it hardware compatible with shields, accessories or circuits designed for older UNO revisions.

 I2C lets you connect multiple I2C-compatible devices in series using only two pins. The controller will send out information through the I2C bus to a 7-bit address, meaning that the technical limit of I2C devices on a single line is 128. Practically, you're never gonna reach 128 devices before other limitations kick in.
 
 The UNO R4 Minima has one I2C bus which is marked with SCL and SDA. They are shared with A4 (SDA) and A5 (SCL) which owners of previous UNOs are familiar with. The pullups are not mounted on the PCB but there are footprints to do so if needed.
