The Board Overview Now, if we look at the Arduino Uno R4 WiFi development board, we can see that it comes with many hardware upgrades over its predecessor. Here is a part marking image of the Arduino ...

Hardware Renesas RA4MA1 Processor (ARM Cortex-M4 at 48 MHz) 256 KiB flash memory and 32 KiB of RAM One user LEDs One reset button One WiFi Transceiver (Arduino UNO R4 WiFi only) One 12x8 LED Matrix ...

Now, the Chinese maker electronics manufacturer Maker Go comes with a solution for that, an Arduino Uno clone for less than half the price of the original board. Maker Go has launched its own take on ...

Arduino UNO R4 Minima specifications and features: Microprocessor: RA4M1 from Renesas Voltage: 5V operating voltage – Extended 24 V tolerance Compatibility: Maintains UNO form factor, pinout ...

Finally, the new board includes a 12-bit analog DAC and operational amplifier. Keeping the pinout, voltage and form factor unchanged from the Uno R3 ensures maximum hardware and electrical ...

RA4M1-R4 core “clone” board (left) vs Arduino UNO R4 Minima (right) Some of the changes include a second row of yellow male headers, a 3.3V/5V switch for Arduino shields, an MD button to enter ...

Arduino also upgraded the R4 WiFi's analog-to-digital converter (ADC), which is responsible for reading data from the analog inputs. On the Rev3, the ADC supports up to 10-bit resolution, with ...

The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.
