Hey Jorge,seems you are not using the newest Arduino IDE or you have to choose the correct board from the board manager (Generic ESP32). The Preferences library is a buildin library.Regards,Moritz

Thank you so much! Glad to hear that it can help somebody :)Have fun and regards,Moritz

Wow, great project and great PCB design! This inspired me to build one my own.I have one question regarding the LiPo protection circuit. Is there something special on the N-channel mosfets you choose? I have noticed there are a few points in the datasheet of the BQ2970 (10.2.2) on how to select the right mosfets, but I was wondering if there isn't any cheaper solution...Regards,Moritz

Regarding to the datasheet on Aliexpress it says 0.3W which is 60mA per pixel... I actually don't know if this could be true. It is the power consumption of the normal 5050 pixels.

Thank you! :)

Wow, thank you! Words like these keep me motivated :)

Thank you so much!

Yeah okay I will have a look and compare these fets. would be nice if it works. :)

Hey GeorgeInst! Thanks a lot. I've heard about the LiFePo batteries but they doesn't excist in the right dimensions for my purpose :( The board files are accessible in this Instructable or on my GitHub Page:https://github.com/makermoekoe/Smarthome-dashbutto...I am currently not selling these with presoldered components.

Hey BerenV! Thanks a lot for your comment. I have tested exactly that procedure with a SIL relay instead of a mosfet. You can see how it works in this video:https://www.instagram.com/p/BlaQTKpnZpU/?utm_sourc...The mosfet idea is even better! But at every time I am searching for a mosfet I didn't find the right one whichs works for my purpose... So maybe you can tell me which mosfet you are using :)Regards!

Hey MarcoB102! Thanks for your positiv feedback! The PCB manufactory I used is a german one called Aisler, which have very decent prices which are only addicted to the size of the pcb. (...much smaller is nearly impossible :D)Regards!

Hey Vidmo! The batteries are nearly the same, that's right. The only difference is, that the voltage of the LIR battery is 3,6v and of the CR only 3v, which doesn't suffice for the ESP.You're absolutely correct with the protection circuit. I have to - and I will add one in the next version. Nice to hear some constructive feedback :)

Hey gdriver! You're correct, but GPIO0 could be floating as well, it doesn't need to be pulled HIGH for normal mode.On version three the GPIO15 is connect with ground plane, so it's always pulled down. The ESP8285-M3 from version one and two doesn't have this GPIO15 pin, it is pulled low inside the metal housing.For EN you are right, maybe I will add a 0603 resistor. I was just to lazy because it works :D

I didn't test out any other interfaces yet, cause I'm very familiar with all the ESP versions. Maybe I will have a look at it by time.

Hey AndrewP! Thanks a lot! I'm currently not using an external antenna. I have had problems to program the ESP8266 because of the LED.. Just have to figure out what's the problem..After this I will do a range test with and without antenne :)
