Unkown tuya chip

The EN on the ESP12F is equivalent to CEN on the Tuya chip.

From your original photo you can see the below circled pins don’t appear to be connected to anything, so those won’t need any wires at all.

Thanks, I’ll take a better look on the pins
Any recommended thin wire size for this?

It’s only tiny currents that are involved so as small as you can find really.

Hello. Did anybody manage to replace the cbu controller? I have this in a zmai 90 and would like to switch to tasmota, so i need an esp on there.

Hello,

Anyone replace this CBU with some ESP?

Thanks

Seems like Moes change internal design but left old name for MS-101. I’ve just received two Moes MS-101 and found plates to flash it with Esphome. I’ve published notes at Перепрошивка Moes MS-101 – Telegraph (as new user I can publish only one embedded media link here).

did you managed to detach the relays?

What do you mean?

To make them dry contact relays

Oh okay, I didn’t make dry contacts. I use Sonoff mini’s for dry contact.

Do you still have a pcb left?

Hi daniel, do you know if there’s an ESP-12 adaptor for CBU chip?
I kinda botched my 2nd pcb with cbu (wires pulled the pcb trace from the board)

No, sorry.

Could I request for CBU adapter?
I don’t really have the skills to create the pcb drawing
Maybe I could send cbu chip/device containing cbu to you?
Also, what’s the average cost & shipping fee if I buy from pcbway?

Look at esp c05 i got 1 and is like cbu chip, i dont try to replace and see if work

Sorry, but no. I am busy with other projects.

Thanks!
do you mind taking a picture of both cbu & c05 side to side?
The c05 looks pretty good other than not having the extra 1 pin on the sides

That’s unfortunate, but thanks
