I am putting together a small project and I am thinking about how I am going to get it to the PCB stage. I am currently making use of a few breakout boards because they are easy to get and they seem to do a good job.

In the case of the TP4056 module would it be ok to just use the whole thing and mount it on my PCB rather than having to replicate the whole circuit on my PCB? enter image description here If that is ok then what would be the best way to solder it to the PCB so that it takes up as little space as possible. I don't really want to put header pins on it as this will make it stick up from the board a bit too much.

thanks SOS

Router the corner off your board and leave generous pads to match the ones on the small PCB. Drop robust wire links into the matching holes and solder. All you loose is the real estate but your board remains the same height.
