4 MB on-board QSPI Flash storage

5 V tolerant GPIOs

Open source C/C++ SDK, MicroPython support

Software-compatible with Pico 1/RP2040

Drag-and-drop programming using mass storage over USB

Castellated module allows soldering directly to carrier boards

Footprint- and pin-compatible with Pico 1 (21 mm × 51 mm form factor)

26 multifunction GPIO pins, including three analog inputs

Operating temperature: -20°C to +85°C

Supported input voltage: 1.8 VDC to 5.5 VDC

> Low-power operation

Low power suspend? In a Pi Foundation product? Impossible.

Not sure why this is downvoted but the sleep and dormant pico examples have quite some issues, they are still in "extras" and not in "core", so while documentation of features is my personal favorite aspect of the pico, there is room for improvement here still.

I wonder how well it's been verified.

[synergy20]

Wow, can't wait. Love the 5V GPIO and security features.

[Daneel_]

5V GPIO is a huge deal for me - this immediately opens up a huge range of integrations without having to worry about line level conversion.

I can’t wait to use this!

[coder543]

I'm having trouble seeing where the datasheet actually says the GPIO pins are 5V tolerant.

EDIT: okay, section 14.8.2.1 mentions two types of digital pins: "Standard Digital" and "Fault Tolerant Digital", and the FT Digital pins might be 5V tolerant, it looks like.

Page 13: "GPIOs are 5 V-tolerant (powered), and 3.3 V-failsafe (unpowered)"

Edit: See comment below; The RP2350 can be powered by a 5V supply.

To clarify: You can connect a 5V power source by connecting it to the VSYS pin which leads into the on-board voltage regulator.

But the µC itself runs on 3.3V and is not totally 5V-capable. You'd need level converters to interface with 5V.

[giantg2]

I'd rather have it run on the lower voltage - generally easier to step down than buck up. Either way, the modules are pretty cheap, small, and easy to find.

[skykooler]

How much tolerance does that have - can it run directly off a 3.7v lithium ion battery?
