Overview

NULA Max RP2350​

Use the full potential of modern microcontroller development with the Soldered NULA Max RP2350.

Built around the powerful dual Cortex-M33 RP2350B processor running at 150 MHz, this development platform combines the familiar Arduino form factor with modern interfaces such as HDMI output, Wi-Fi/Bluetooth connectivity, and advanced PIO (Programmable I/O) capabilities.

Designed for expandability and ease of use, the NULA Max includes a Qwiic port for quick sensor integration, a microSD slot for data logging and media playback, and a Raspberry Pi Radio Module 2 providing native Wi-Fi and Bluetooth.

Its dual-header layout exposes up to 48 GPIO pins, with dedicated lines for wireless and HDMI functions, allowing ambitious projects without sacrificing simplicity. Whether you’re building an HDMI weather dashboard, a robot controller, or an IoT gateway, the NULA Max RP2350 is engineered to scale with your creativity.
