Excellent upgrade from RP2040

The RP2350 chip offers a noticeable performance boost. The dual architecture support allows me to experiment with both Arm and RISC-V cores seamlessly. Great for advanced embedded projects.

Robust connectivity options

The pinout is well thought out. I easily interfaced multiple sensors via I2C and SPI simultaneously. The USB-C power delivery is a nice modern touch.

Perfect for industrial prototyping

Used this for a motor control prototype. The increased SRAM and faster clock speed handled complex PID loops without breaking a sweat. The build quality of the board is solid.

Great board, learning curve exists

Hardware is fantastic, but if you are coming from standard Arduino boards, there is a bit of a learning curve with the new SDK features. Once set up, it runs beautifully.

5 FAQ

Q: Can I power this directly from a 3.3V source?

A: It is recommended to use the 5V USB-C or VIN pin. The board has an onboard regulator to step down to 3.3V. Direct 3.3V injection bypasses protection circuits and is not advised.

Q: Is there built-in WiFi or Bluetooth on this core board?

A: No, the RP2350 chip itself does not include wireless radios. You will need to attach an external module via UART, SPI, or I2C for WiFi/Bluetooth functionality.

Q: Is the 16MB version backward compatible with RP2040 code?

A: Mostly yes. While the pinout is similar, the RP2350 has architectural differences. You may need to update your SDK and recompile, but logical porting is straightforward.

Q: Does this board support external PSRAM expansion?

A: Yes, the RP2350A supports external PSRAM via the QSPI interface, allowing for significant memory expansion beyond the on-chip SRAM.

Q: What debugging interfaces are available on the header?

A: The board exposes SWD (Serial Wire Debug) pins on the standard header, compatible with Raspberry Pi Debug Probe and other standard ARM/RISC-V debuggers.
