2D Barcode Scanner SEN-18088 pin-out

The silk screen for the 6-pin connection on the board reads:

STAT TRIG 3.3V RX TX GND

But the Schematic and the board layout diagram shows:

STAT TRIG 3.3V TX RX GND

i.e the TX and RX connections are reversed.

Which version is correct?

I’d go with the silkscreen (usually if there is a silkscreen error it gets noticed quick…schematics errors are harder to notice & fix)

Be sure to update this thread if that is not the case :slight_smile:

Thanks! I’ll try that.

I tried it. The silkscreen is correct.
