Took me some time, but I think I’m finished with routing now. Going to let it cool down over the weekend and place a factory order next week for a test batch. I’d appreciate it if any of you could help me test the board. In the end, I’d like to open-source the final design and donate it to the community, basically, while I plan to keep it in production for anyone interested in a ready-to-use kit.

Hey folks, I finally have the board on the desk. Doing some basic testing, at this point on ESPHome (simpler for me)
- RGB LEDs work (12x)
- SD card read/write works
- NFC (RC522) works fine
- GPIO expander - detected on the bus (0x20), but no input changes, perhaps ESPhome bug or i’m mising something
- DAC works well
- Battery charging and power status - OK, battery voltage read - OK
- Power button - works well, by default device is on, when pressed for around 3 seconds - goes off.
- Rotary works well.
- The only hardware issue found so far - when battery connected, flashing not working with USB-C, bootloop. Wierd… Without battery it works every time. With battery works with OTA. Not critical, will have a look later.
I’m trying to configure ESPuino for next test, but getting bootloop, any ideas what do I miss? Something with the sdcard (it is instered and formatted to FAT32 i think)?

Your i2c-configuration (4 / 2) is entirely wrong.
Guess those reboot-problems are introduced because you configured GPIO 2 as SDA while it is in fact used for SDMMC.
Thanks for pointing this out. Updated to right pins, but no change. Bootloop with the same message. Changed the sdcard, just to be sure, but made no difference

Don’t know, maybe a timing problem. Try to integrate a/some delay(s) within setup().
Make sure all GPIOs are assigned according your schematics.
I managed to get rid of NVS error by increasing NVS partition size. Not sure why I’m having this issue. Disabled sdcard for now, although I have it tested in the simple sketch and it works well.
I’m running into another issue:
