Since the USB interface of MC509 module supports USB 2.0 full speed, the resistance “RV102 and RV103” in the 0must be Voltage Sensitive Resistor with small capacitance (ALVC18S02003 manufactured by AMOTECH or B72590T7900V60 manufactured by EPCOS is recommended.). In addition, The layout design of this circuit on the DTE board should comply with the USB 2.0 full speed protocol, with differential lining and impedance control to 90 ohm

It is recommended that set USB D+ and USB D- pins as test points and then place these test points on the DTE for debug.
