2A. Ensure low resistance of power supply trace in design to avoid voltage drop. Never use a diode to make the drop voltage between a higher input and module power. Otherwise, Neoway will not provide a warranty for product issues caused by this. In this situation, the diode will obviously decrease the module performances, or result in unexpected restarts, due to the forward voltage of the diode will vary greatly in different temperature and current.

BT antenna 3.7.1 ANT Interface ANT BT and GNSS antenna of N58 require a characteristic impedance of 50 Ω. You should control the impedance of the traces between the pins and antenna to ensure the RF performance. An impedance matching circuit, such as the L network, split capacitor network, and pi network is mandatory in between.
