This little board is ESP based and doesn't come from Adafruit so you can't enter bootmode to open up a local drive. You have to install circuitpython over serial connection. The easiest way to do this is from the CP install page's new 'open installer button'. You must do this part on Chrome.

1. plug the device into your computer using a USB cable. make sure it's a data cable, not just power.
2. Hold the boot button, click the reset button, then release the boot button. It should be in bootmode. From the commandline on a a mac you should be able to see the serial port using ls -l /dev/tty.*.
3. Go to the CircuitPython release page using Chrome.
4. Click the 'open installer' button (on the right side below the purple download buttons). image here
5. Click the 'Upgrade CircuitPython 9.2.1 Bin Only' link in the dialog and follow the prompts. Assuming the device's serial port was found you should have CP installed after a minute or two.
6. Reboot the device and the CIRCUITPY drive should come up.
