Raspberry Pi Pico 2 upgrades the Pico with the RP2350 microcontroller, dual cores up to 150 MHz, more SRAM, and modern security features. Same footprint and pinout as the original Pico, so it drops into existing designs.
Extra headroom for robots, IoT devices, test instruments, and control systems that need more signal processing and I/O.
Specs
| Microcontroller | RP2350, dual Arm Cortex-M33 or dual Hazard3 RISC-V cores @ up to 150 MHz |
| SRAM | 520 kB on-chip |
| Flash | 2 MB on-board |
| Voltage | 1.8 to 5.5V DC via VSYS |
| Peripherals | 2 × UART, 2 × SPI, 2 × I²C, USB 1.1 (host/device) |
| Security | Boot signing, OTP key storage, hardware SHA-256 accelerator |
| Programming | UF2 drag-and-drop, C/C++ SDK, MicroPython |
| Form factor | Pico-style board, castellated pads, 40-pin footprint |
GPIO runs at 3.3V, level-shift any 5V signals. Ships header-less unless the variant says otherwise.
FAQ
Will this ship from Manila?
Yes — all stock ships from our Quezon City warehouse. Order before 4 PM weekdays for same-day cutoff via J&T or LBC.
Do you ship nationwide?
Yes. Metro Manila usually arrives next-day; provincial 1–3 working days.
Can I get this on a school PO or class order?
Yes — we accept Purchase Orders from accredited schools and universities. Contact us with your PO details and we'll process it.
Is this compatible with Arduino, ESP32, or Raspberry Pi?
Most parts work with common maker boards — check the description for specific pinout / voltage notes. If you're unsure, send us a message before ordering.
What's your return policy?
7-day inspection window for DOA units. Email proof of issue and we'll ship a replacement or refund. Used / installed parts are not returnable unless faulty.
Do you offer technical support?
Yes — questions land on our forum or via email, weekday or weekend. We've actually wired up most of what we sell.
