1. Does Arduino Uno R4 have Wi-Fi?
Yes, the Arduino Uno R4 features built-in Wi-Fi thanks to the integration of the ESP32-S3 Wi-Fi module.
2. Does Arduino Uno R4 have Bluetooth?
Yes, the Arduino Uno R4 also comes with built-in Bluetooth, facilitated by the same ESP32-S3 module.
3. What is the main difference between Arduino Uno R3 and R4?
The Arduino Uno R4 is better than the Uno R3 because it has improved parts. It comes with a Renesas RA4M1 48MHz Arm Cortex M4 processor, which gives you 32KB of RAM and 256KB of storage space. It also has a USB-C port and can handle up to 24 volts. Plus, it supports CAN, as well as the usual I2C, SPI, and UART interfaces, making it great for more complicated projects.
4. What are the new features of Arduino Uno R4?
The Arduino Uno R4 comes with some exciting new features:
- It has a 32-bit microcontroller board.
- It has bigger memory, 256 kB of flash memory and 32 kB of SRAM.
- It runs faster with a clock speed of 48 MHz, which is three times faster than older versions.
- It has integrated Wi-Fi and Bluetooth connectivity through the ESP32-S3 module.
It comes with an onboard 12x8 LED matrix for visual feedback and customization.
5. What is the speed of Arduino Uno R4?
