Hi everyone,

I want to have this solar lamp with only 100% full light mode.

The board is similar to the yx-402.

This is the photo of the board:

I want the 100% bright mode.
Keep the function that allows the solar panel to turn it off when it detects ligth, keep the remote control

Welcome to AAC,

Unless you want to use an MCU or some discrete logic to operate the remote for you, you can’t do what you want.

U1 on that PCB is an unmarked mystery MCU and the changes would have to be made to the firmware on it—that’s not going to happen. This leaves only the remote control, and you could interface to it and run a sequence of virtual keypresses to get what you want… you could but it would make more sense to make your own controller board at that point.

If you expected to just remove something, there is no project wit such a small scale that will solve your problem, sorry.
