Debug of the LE940B6 Module in Production
To test and debug the mounting of the LE940B6 module, we strongly recommend to add
several test pads on the application board design for the following purposes:
• Checking the connection between the LE940B6 itself and the application
• Testing the performance of the module by connecting it with an external computer
Depending on the customer application, these test pads include, but are not limited to the
following signals:
• TXD
• RXD
• ON_OFF_N
• SHUTDOWN_N
• RESET_N
• GND
• VBATT
• VAUX/PWRMON
• TXD_AUX
• RXD_AUX
• USB_VBUS
• USB_D+
• USB_D-
• Signals for analysis
