The case is designed to hold the corners of the ESP32 opposite the USB-C down (you slide the corners under the corner ribs), which should give the perfect fit. If not, then try trimming the solder under the board with a flush cutter.
Parts list:
– ESP32-C3 supermini: https://a.aliexpress.com/_Ezrsi9c
– HDMI female connector: https://a.aliexpress.com/_EJRClNs
– HDMI male connector: https://a.aliexpress.com/_EvvYhvy
– Jumper wires: Any thin wires will do. Needs to be soldered on.
On the ESP32-C3 supermini I use GPIO10 for data/CEC, since it is conveniently placed.

When using the dongle version (male connector), remember that it also needs USB power when the TV is turned off. Otherwise, it won’t be able to turn the TV back on.
If your TV or receiver doesn’t have an “always on” USB port (and you don’t want to stick a power adapter on the back of your TV), you may prefer the female connector version. Then you just run an HDMI cable to the TV and have the power supply for the ESP32 next to the other power supplies for your Apple TV, PlayStation etc.
