Arduino Uno R4 Minima WiFi Development Board
Arduino Uno R4 Minima WiFi Development Board
The Arduino
Uno R4 – Minima WiFi Development Board is the next-generation upgrade of
the legendary UNO series, featuring the Arm® Cortex®-M4
microcontroller running at 48 MHz. It brings enhanced performance,
improved memory (256 kB Flash, 32 kB SRAM, 8 kB EEPROM), and advanced
peripherals such as a 14-bit ADC, 12-bit DAC, OPAMP, and
Capacitive Touch Sensing Unit.
Supporting multiple communication interfaces (UART, SPI, I2C, CAN), this board
is ideal for IoT projects, robotics, automation, and sensor-based applications.
With USB-C and barrel jack power options, the UNO R4 Minima combines
flexibility, efficiency, and backward compatibility with the Arduino ecosystem.
Features:
· High-performance Arm® Cortex®-M4 (48 MHz) MCU
· RTC (Real-Time Clock) with MPU support
· 14-bit ADC for precise analog readings
· Up to 12-bit DAC for accurate signal output
· Onboard Operational Amplifier (OPAMP)
· Capacitive Touch Sensing Unit (CTSU)
· Multiple
power input options (USB-C or barrel jack)
· CAN interface support for automotive and industrial projects
Applications:
· IoT-enabled smart devices
· Robotics and autonomous
systems
· Data acquisition and
real-time monitoring
· Sensor-based automation
projects
· Educational prototyping
and embedded system design
