Need a pinout for connecting a Bluetooth module based on BC215

Question

Arduino

I am looking for a wiring diagram for such modules. It visually differs from Chinese folk HC-04/05 in that it has contacts on only one side. On the opposite side, there is only one single contact, but judging by the fact that it was not soldered, it was not used. Intersue pin numbers for power and RX / TX.

Answer 1

I tried to copy it to a soapbox, but at least you can see it. Unfortunately, only one side of the

power supply was found, these are the first two soldered contacts on the right. but of the four remaining, I would like to find a dock for RX and TX.

Answer 2

BC215 is just an IC. Modules can be wired in different ways. Therefore, it is impossible to specify the pinout of the module knowing only the microcircuit on it.
Is there a picture of the module on both sides? If not, then you can only find contacts usually by ringing signals.
