ESPHome
Easy Installer
If you order from us, your FLIP_C3 or FLIP_C3 based device should have a pre-installed version of ESPHome, but if you need to reinstall this base firmware, we've set up an easy installer on our main website. This will allow you to use Chrome or Edge to install it via a USB-C cable. Current versions cannot be connected via USB-C while powered via the buck converter.
You may need to hold the BOOT button as you connect the USB cable. Alternatively you can hold the BOOT button while you press and release the RESET button if the FLIP_C3 is already connected via USB-C. Hold the BOOT button for a couple seconds after the device is connected to your computer and then proceed with the installation above. Once complete, power cycle the FLIP-C3 with the RESET button or disconnecting and reconnecting the cable. You can also use this time to swap to a DC power source via the 2P spring connector.
Adopt In ESPHome
Once you've followed the steps to connect your FLIP_C3 to Wifi, you should see it in the ESPHome dashboard available to be adopted. Adopting into ESPHome will generate a base YAML that references our YAML file on Github as an external package with the following lines:
This includes references to all the basics of the hardware and more. This includes the onboard WS2812, the red status LED, the Boot Button on GPIO9 and I2C is defined at id: bus_a
You can add ESPHome YAML to the end of this to get started quickly.
YAML Reference
The following are snippets to properly interact with FLIP_C3 hardware in ESPHome
Direct reference to the YAML we ship with is available on Github:

We're still working on organizing and modularization. Feel free to help out. There's a lot more in there than referenced here.
Board Definition
If you like, you can easily start a blank ESPHome device based on the ESP32-C3 using esp32-c3-devkitm-1
board type. This is default in ESPHome for C3 based boards and we use chip level pin numbers on our silkscreen.
Boot Button
The BOOT
button is available in software on GPIO9
after boot. If held during boot, FLIP_C3 will be put into bootloader/flash mode.
WS2812
Status LED
