Using the IPEX antenna connector #40

Closed radioralph closed 4 months ago

radioralph commented 6 months ago

I wish to use an external antenna with the T-Display S3 AMOLED. Is the IPEX socket connected, or do resistors/capacitors need to be inserted or removed?

Thank you @isthaison for your observation regarding the antenna connector on the T4-S3 board. The schematic diagram for the T-Display-S3 suggests that some components will need to be added to enable the IPEX connector, and some components will need to be removed to disable the on-board 3D antenna. The resistors noted are 0R, but the cap values (if required) are not mentioned.

If I am correct in my understanding, the question becomes: what are the recommended values and placement locations of the added/removed components?

Best regards,
