First of all, thank you for sharing your fantastic PCB project. I’ve been using it as part of a large LEGO MOC I’ve been working on for nearly two years—a detailed church tower made of over 30,000 pieces. Your board has been instrumental in lighting up all the floors with RGB and white lights, and everything works superbly. I really appreciate your work and generosity in making this available.
The model will soon be displayed inside the actual church and later in a local museum. Since not all of these locations have WiFi, I’d like to add some physical push buttons to control the lights offline.
I managed to modify the ESPHome firmware and solder two wires directly to the ESP chip, but it feels quite fragile and not suitable for long-term use. Ideally, I’d love to have a modified version of the PCB that exposes a few additional GPIO pins through JST SUR connectors for button input.
For my needs, just 3 GPIOs and ground would be sufficient—so either one 4-pin connector (GND + 3 GPIO) or three separate plugs would work.
The GPIO pins need to support pullups, GPIO34-39 does not support that.
Would you be open to helping with this modification? I’d be happy to pay for your time and effort. Please let me know if this is something you’d consider.
Thanks again for the amazing project
P.S. I couldn't find you contact information. If you'd like to discuss this further as Github issue tracker might not be the right place you can contact me on bgerritsen_at_gmail_dot_com
