Digital/Power Connector
The digital connector provides power, serial communications signals, shutdown and reset signals to the
M6e module, and access to the GPIO inputs and outputs. These signals are provided through connector
part number: Molex 53261-1571 - 1.25mm pin centers, 1 amp per pin rating, which mates with Molex
housing p/n 51021 -1500 with crimps p/n 63811-0300. See
typical cable parts.
Reconnection to the module may not possible if the host PC is restarted while auto read is in progress. To
reconnect to the module, the user must either reboot the module or unplug and re-plug the USB cable.
