+
+![Ploopyco Trackball Nano 2](https://cdn.ploopy.co/nano2-media-assets/site-photos/_MG_2495.jpg)
+
+It's a DIY, QMK Powered Trackball...Nano!
+
+* Maintainer: [PloopyCo](https://github.com/ploopyco)
+* Key contributors: [Drashna Jael're](https://github.com/drashna/), [Germ](https://github.com/germ/)
+* Hardware Supported: RP2040

+
+Make example for this keyboard (after setting up your build environment):
+
+    make ploopyco/nano_2/rev2_003:default
+
+Flashing example for this keyboard:
+
+    make ploopyco/nano_2/rev2_003:default:flash
+
+# Building Firmware
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
+
+# Triggering the Bootloader
+
+[Do you see those two golden holes in the board](https://ploopy.co/wp-content/uploads/2023/11/boot.jpg)? Those are called **vias**. They act exactly like a switch does. Right now, that switch is OFF. However, if you take a paperclip or a pair of metal tweezers and touch those two vias, the two vias will form an electrical connection. Effectively, that switch turns ON.
+
+Go ahead and connect the two vias, and then (while the vias are connected) plug in the Nano 2 board into your computer.
+
+The computer should recognise that a mass storage device was just plugged in. Once this is done, you should be able to drag and drop files onto the Nano 2 board, as if the board was a USB drive. Feel free to remove the tweezers or paperclip at this point.
+
+If you want to upload a new firmware file (a ".uf2" file, like "nano-2-awesome-version.uf2" or something), just drag it into the folder, and it'll automatically install on the Nano 2 board and restart itself, in normal operating mode. You're done!
+
+**TIP**: If your firmware is in some kind of strange state and uploading new firmware isn't fixing it, try uploading [a flash nuke](https://learn.adafruit.com/getting-started-with-raspberry-pi-pico-circuitpython/circuitpython#flash-resetting-uf2-3083182) to the Nano 2 board before flashing the new firmware. It wipes the memory of the Nano 2 board completely clean, which can help clear a few types of errors.

+# Customizing your Ploopy Nano 2
