ⓘ Tips

• Before flashing, please put your Raspberry Pi Pico™ chip in the bootloader mode by keeping the BOOTSEL button pressed while powering up. For more information, please take a look at your board's datasheet.
• If you find yourself unable to perform any of the operations, please navigate to the troubleshooting, and the Q&A pages.
• The "🔍 Check installed version" button doesn't send your firmware to the Internet. Instead, its algorithm compares the firmware builds' UF2 block hashes safely in your web browser.
• The installed firmware version is compared only with all the different versions (builds) of the same project.
• Exercise caution while exploring projects of unknown origin. In principle, anyone can publish their firmware here. Projects endorsed by this website will always come with the "submitted by flashmypico" text written just below their title.
• A part of your chip's unique RANDID number may be sent to the server if this project's author has enabled the installed version tracking feature. This number will only be logged if the project's author already has it, and has used it to enable this feature for this particular board.
