Arduino UNO R4 Minima

Overview

The Arduino UNO R4 Minima is a latest new upgrade to the popular and world famous Arduino UNO R3 board. UNO R4 has the same form factor as the UNO R3 measuring 68.58 x 53.34 mm in dimensions. UNO R4 Minima comes with a Renesas RA4M1 (Arm® Cortex®-M4) a 32-bit microprocessor clocked at 48 MHz, expanded menory with 32kB of SRAM and 256kB of flash memory and supports 5V operating voltage.

Apart from the improved performance and expanded memory, it has an onboard RTC (Real Time Clock), DAC (Digital to Analog Converter), 14-bit ADC (Analog to Digital Converter), OPAMP (Operational Amplifier) and a MPU (Memory Protection Unit). All these features eliminate the need for additional components in projects, simplifying the design process.

The UNO R4 Minima’s user-friendly design makes it easy to learn for beginners, while its powerful features provide ample room for experienced users to explore more complex projects. Whether you’re building a sophisticated robot with advanced motor control or developing a data logger that captures and analyzes intricate sensor readings, the UNO R4 Minima has the power and memory to handle your project’s needs.
