Explorer comes pre-flashed with MicroPython, our own custom drivers/libraries and a range of examples to get you started. MicroPython support for the RP2350B is currently a work-in-progress, so you should be prepared to update as we make fixes and improvements!
To upgrade, grab the latest release from https://github.com/pimoroni/explorer/releases/latest
There are two choices of firmware:
- explorer-vX.X.X-micropython-with-filesystem.uf2
⚠️ (recommended) - A full update package including examples and the explorer library - explorer-vX.X.X-micropython.uf2 - a firmware-only update, that will leave your filesystem alone!
with-filesystem version, the contents of your Explorer board will be erased- so make sure to back up your own code first. Alternatively you can flash the firmware-only build and manually copy the files in examples/lib
- Connect Explorer to your computer with a USB Type-C cable
- Put your Explorer into bootloader mode by holding down "BOOT", the second button from the left when holding Explorer with the screen facing away from you. Keep holding "BOOT" and press "RESET", the button next to "BOOT".
- Drag and drop your chosen
.uf2file onto theRP2350drive that appears. - Your board should reset and, if you used the `with-filesystem build, should display a menu of examples.
We've tried to cover all the bases with some simple examples to get you started. See examples/README.md for more information.
To help you get started we've created a function reference. See docs/reference.md
