1 amp per pin rating. which mates with Molex housing p/n 51021-1500 with crimps p/n
63811-0300).
The pin definitions are the same as for the M6e, for the functions that are supported by
both, with one exception: The “SHUTDOWN” line of the M6e has reversed polarity and is
the “ENABLE” line in the ThingMagic Nano.
The UART RX and UART TX lines are buffered on the carrier board. This makes the
inputs 5V tolerant and increases the output current driving capability from around 10 mA
to around 15 mA.
Diodes are also added on all I/O lines to increase the ESD protection.
