Description
Use the full potential of modern microcontroller development with the Soldered NULA Max RP2350. Built around the powerful dual Cortex-M33 RP2350B processor with 520KB on-chip SRAM, this development platform combines the familiar Arduino form factor with modern features like DVI output, WiFi/Bluetooth connectivity, and PIO (programmable I/O). Perfect for makers tackling robotics, display-driven projects, and IoT applications requiring processing power and connectivity options.
Made with both simplicity and expandability, this board features a Qwiic port for sensor integration, a microSD slot for optional data logging and media projects, and a Raspberry Pi Radio Module 2 providing reliable and native WiFi and Bluetooth connectivity. The dual header design exposes much more of the RP2350's pins than other boards, leaving some pins exclusive for WiFi communication and DVI out. With DVI output capability, you can drive displays directly while maintaining full Arduino IDE compatibility.
If the RP2040 board is Arduino Nano, this is your Arduino MEGA. Packed with professional features yet accessible to makers of all skill levels. Whether you're building weather stations with DVI displays, robotics projects requiring extensive GPIO, or IoT systems needing WiFi connectivity and data logging, the NULA Max RP2350 provides the feature set and expandability your projects demand. EU manufacturing ensures consistent quality and reliable performance for both prototyping and production applications.
Note:
- This board IS NOT 1:1 compatible with Arduino UNO shields, please refer to the pinout
- Before connecting the 3.7 Li-Ion Battery, please refer to the detailed technical documentation which you may find on this page
