I have already disassemled it.
It seems it has four? pins used for driving leds (RGBW) and one is probably used to detect “touch” - well actualy, i believe it does not detect touch but vibration (using that black cylinder?)
Does anyone has configuration for tasmota or esphome?
I can see, that GPIO 2,4,5,15,16 are connected to traces.
I can’t see all the traces on the board or how the connections are labelled, but I am not entirely convinced you have it right. GPIO0 has to be grounded to get into boot mode. Pinouts are here https://randomnerdtutorials.com/esp8266-pinout-reference-gpios/ (1st diagram).
A picture of the board with the connection labels clear would be helpful.
Yeah i think i have it, there is pad IO0 (left side of my picture), i have it connected to ground. It is connected on GPIO0 pin on ESP module. I have google yesterday and problem might be with low power delivered from USB - all LEDs are on. Iwiil try to power it from it’s battery instead of USB
Ok, i just cannot pinpoint how to detect the “touch” event. I’m pretty sure, it is detected by that black cylinder, as a vibration. I tried setting up button on GPIO 0,2,15,16 , also on GPIO 1,3 . And to read voltage from A0 , no luck on any of these.
