NOTE：
a. RF traces need to keep 50ohm impedance.
b. PIN_15 actives low WLAN disable, no connecting when using; the same as PIN_38.
c. Module’s BT UART_TX connects to reference circuit’s RX, UART_RX connects to reference circuit’s TX.
d. VDIO 3.3V for default speed and high-speed modes, 1.8V for SDR12/SDR25/SDR50/DDR50 modes.
