Hi! I have just received 02 new KC863-A16 boards. One was sent free of charge, and the other I bought as a spare. Both are functioning correctly. The firmware was downloaded, and I can "see" the WiFi AP, and access the programming interface at the address http://192.168.4.1. Super! Thank you for your support.
Now I am struggling with the RF TX/RX modules. When I plug them in, the board´s LED goes off, the programming interface freezes, and the WiFi also goes off. I double-check the connections (GRD to GRD pins), and my first thought is that these modules might be defective and/or incompatible. Fortunately, there is no sign of damage once they are removed. Any hints here? Can you please help me with the module specifications?
