FAQ
1. What is the difference between Raspberry Pi Pico 2 and Pico 2W? Which one should I buy?
The Raspberry Pi Pico 2 and Raspberry Pi Pico 2W share the same core hardware: RP2350 microcontroller with dual‑core ARM Cortex‑M33 / dual‑core Hazard3 RISC‑V at 150 MHz, 520 KB SRAM, and 4 MB Flash. The only difference is that the Raspberry Pi Pico 2W adds an Infineon CYW43439 chip supporting 2.4 GHz Wi‑Fi 4 and Bluetooth 5.2. Choose the Raspberry Pi Pico 2W if your project needs wireless connectivity; otherwise, the Raspberry Pi Pico 2 offers the lowest power consumption and cost.
2. How does the RP2350 chip on the Pico 2 compare to the RP2040 on the original Pico?
The CPU on the Raspberry Pi Pico 2 upgrades from dual Cortex‑M0+ to dual Cortex‑M33 (switchable to dual RISC‑V), clock speed increases from 133 MHz to 150 MHz, on‑chip SRAM grows from 264 KB to 520 KB, and onboard Flash doubles from 2 MB to 4 MB. New features of the Raspberry Pi Pico 2 include a hardware FPU, DSP extensions, faster PIO blocks, a true random number generator, and enhanced secure boot.
3. Can I run MicroPython or Arduino code on the Pico 2?
Yes. Official MicroPython firmware and a C/C++ SDK are available for the Raspberry Pi Pico 2 and Raspberry Pi Pico 2W, and the community has quickly released an Arduino‑Pico core. You can write, compile, and upload programs directly in the Arduino IDE for the Raspberry Pi Pico 2, or use the familiar MicroPython REPL for interactive development.
4. How does switching between the dual‑core RISC‑V and dual‑core ARM work? Do I need special code changes?
At boot, you can choose whether to run the ARM cores or the RISC‑V cores on the Raspberry Pi Pico 2 and Raspberry Pi Pico 2W. With the C/C++ SDK, you simply specify the architecture in your CMakeLists.txt, and the compiler generates the appropriate instructions for the Raspberry Pi Pico 2. Both cores must run the same instruction set; you cannot mix ARM and RISC‑V simultaneously.
5. How well does the Pico 2W’s Wi‑Fi and Bluetooth perform? What wireless applications are possible?
The Raspberry Pi Pico 2W supports 2.4 GHz Wi‑Fi 4 (802.11n) with typical TCP throughput of tens of Mbps—enough for IoT data reporting, OTA updates, and lightweight HTTP/MQTT communication. Bluetooth on the Raspberry Pi Pico 2W supports both Classic and BLE, allowing connection to phone apps, Bluetooth sensors, or operation as a BLE beacon.
6. What improvements does the PIO have on the Pico 2? Is it compatible with original Pico PIO code?
The number of PIO blocks on the Raspberry Pi Pico 2 increases from two to three (12 state machines total), with an enhanced instruction set and more flexible I/O mapping. PIO assembly programs written for the RP2040 can run unmodified on the Raspberry Pi Pico 2 after recompilation.
7. Is 520 KB SRAM enough? What can I do with it compared to 264 KB?
The nearly doubled SRAM allows the Raspberry Pi Pico 2 and Raspberry Pi Pico 2W to handle larger frame buffers, deeper communication stacks, and more complex algorithms. For example, you can drive higher‑resolution color TFT displays on the Raspberry Pi Pico 2 while running a lightweight GUI framework like LVGL.
8. How do I program the Pico 2 / Pico 2W? Is an external debugger required?
Just like the original Pico, the Raspberry Pi Pico 2 and Raspberry Pi Pico 2W include a USB bootloader. Hold the BOOTSEL button while connecting the USB cable, and the Raspberry Pi Pico 2 appears as a removable drive; drag‑and‑drop a UF2 file to flash.
9. What is the power consumption of the Pico 2? Is it suitable for battery operation?
Thanks to a more advanced 40 nm process and improved power management, the Raspberry Pi Pico 2’s dynamic power consumption is noticeably lower than the original Pico. The Raspberry Pi Pico 2 is well‑suited for battery‑powered remote sensors, portable instruments, and low‑power IoT nodes.
10. Can I integrate the Pico 2 directly onto my own PCB? What should I watch out for?
The Raspberry Pi Pico 2 retains the same pinout and mounting holes as the original Pico, allowing a direct drop‑in replacement in most existing designs. For a more compact integration, you can design a baseboard around the RP2350 chip itself or use a stamp‑hole module compatible with the Raspberry Pi Pico 2.
