Special Features
R3 PRO uses a more powerful ARM Cortex-M4. This processor operates at a frequency of up to 48MHz and is equipped with 32KB of RAM and 256KB of flash memory. uno is equipped with a Cortex M4 microcontroller, which greatly increases the processing power of the Cortex M4 microcontroller by 3 times to 16 times.
uno uses a USB-C interface instead. This new interface not only provides faster data transfer speeds, but is also more versatile and can connect to almost all modern devices. In addition, uno supports 24V Vin input voltage, making it compatible with a wider range of power supplies.
The uno does not have wireless connectivity and can be connected to other wireless modules through the Qwiic connector, providing greater flexibility. Through the I2C interface of uno, you can connect various I2C devices, such as Erha image recognition sensor, speech synthesis module, speech recognition module, NFC module, LCD screen, etc.
48 MHz Arm Cortex-M4 microprocessor with floating point unit (FPU), 256 kB Flash, 32 kB SRAM, 8 kB data memory (EEPROM) 14 digital pins (GPIO), 6 analog input pins pin (ADC), 6 PWM pins, recommended input voltage (VIN) is 6-24 V, 5 V operating voltage, 1 * UART (pin D0, D1),1 * SPI (pin D10-D13, ICSP header),1* I2C (pin A4, A5, SDA, SCL),1* CAN (pins D4, D5, requires external transceiver)
The uno is a game-changer in the electronics world with its advanced ARM Cortex-M4 chip, enhanced compatibility, and additional Wi-Fi and Bluetooth connectivity. Its upgraded features coupled with a user-friendly design make it ideal for both beginners and experienced looking to push the boundaries of creativity.
