Debug of the LE920 in production
To test and debug the mounting of LE920, we strongly recommend to foresee test pads on the
host PCB, in order to check the connection between the LE920 itself and the application and
to test the performance of the module connecting it with an external computer. Depending on
the customer application, these pads include, but are not limited to the following signals:
x
TXD
x
RXD
x
ON/OFF
x
RESET
x
GND
x
VBATT
x
TX_TRACE
