Product description: Arduino Nano R4 - ABX00142
The Arduino Nano R4 is a compact Arduino board based on the same Renesas RA4M1 microcontroller as the Arduino Uno R4 Minima , combining a small form factor with high performance. The board is equipped with 256 KB of Flash memory and 32 KB of RAM , offering 14 digital pins, 6 PWM channels, and 8 analog pins . The board features solder pads, making it ideal for surface-mount (SMD) applications on custom PCBs . It maintains compatibility with the Arduino ecosystem , offering familiar tools and libraries, and the presence of two I2C interfaces – 3.3 V (Qwiic) and 5 V – enables easy expansion of functionality. This version of the board does not come with pre-soldered connectors .
Arduino Nano R4 - ABX00142.
Botland is an official distributor of the Arduino development platform in Poland. We offer a wide choice of boards, modules and accessories from this popular brand, along with tutorials and a knowledge base for users. All Arduino products presented here are original.
The built-in Qwiic connector facilitates integration with a wide range of sensors and peripherals.
Main features of the Arduino Nano R4
- High-performance RA4M1 microcontroller : 256 kB Flash, 32 kB RAM, compatible with UNO R4
- Compact size of 4.3 x 1.7 cm : ideal for applications with limited space
- Solder pads : enable surface mounting on custom PCBs
- Single-sided design : facilitates automated SMD assembly
- Qwiic connector : allows for quick connection of sensors and accessories
- Programmable RGB diode : visual indication of operating status
Comprehensive interfaces and connectivity in a compact form factor
The Nano R4 offers a rich set of interfaces, including 14 digital pins, 8 analog inputs, 6 PWM channels, 1x UART, 1x SPI, and 2x I2C (5V and 3.3V - Qwiic). The board also includes a USB Type-C connector, a linear voltage regulator (VBAT), and standard LED and RGB LEDs. The pinout and types are consistent with the Nano family , ensuring compatibility with existing accessories. Power can be supplied via the USB Type-C port or an external voltage source ranging from 6V to 21V , connected to the VIN pin.
Practical applications
- Embedded systems in industrial automation
- Miniaturized robotic designs and automation
- Prototypes moving into series production
- Custom Platforms and Commercial Products
The Arduino Nano R4 is ideal for integration into compact and space-constrained applications.
The board has no connectors. We also offer a version of the board with pre-soldered connectors.
