BOOTSEL Mode

Users can enter BOOTSEL mode by holding down the BOOT button, when the USB connection is made to a computer. The board will remain in this mode until it power cycles (happens automatically after uploading a .uf2 firmware file) or the RESET button is pressed. The board will appear as a USB mass storage device under the name RPI-RP2.

Note: DO NOT remove batteries by pulling on their wires. Instead, it is recommended that pair of dikes (i.e. diagonal wire cutters), pliers, or tweezers be used to pull on the JST connector housing, to avoid damaging the battery wiring.

Headers

The pins for the RP2040 Thing Plus are broken out to 0.1"-spaced pins on the outer edges of the board. When selecting headers, be sure you are aware of the functionality you need. If you have never soldered before or need a quick refresher, check out our How to Solder: Through-Hole Soldering guide.

The Feather Stackable Header Kit is a great option as it allows users to stack shields (w/ Feather footprint) or it can be placed on the a breadboard; while, the pins are still accessible from the female/male headers.
