    Colleagues,

    Can anyone unravel what is on the attached board and what it is for? Probably it is a board that serves as a power supply platform for the board https://www.cdebyte.com/products/EoRa-S3-900TB/7 and is supposed to be used to connect an external antenna to this module.

    I have searched, but it is probably custom made.

    Thank you in advance for your help.

    Greetings Green circuit board with various electronic components and a connector for an external antenna.

    Give such a photo so that it can be enlarged. The radio is already on this board, I don't see any similarities to the one in the link.

    3- Radio circuit
    4- Vibrating motor

    This could be a combination of LoRa and WiFi, as suggested by the two antennas in the assembled device.

    It would rather not make sense, most RF circuits have an amplifier built in and besides, what would be the point of sending the RF signal via pin connectors? For this you need coaxial connectors such as U.FL or similar. In this finished device you can see antennas for two different bands.
