Serial-USB Module ... uses pin 7 on socket type U


In the schematic for the Serial-USB Module ( it shows Pin 7 connected to RTS. However, the Gadgeteer definition for a type U socket marks pin 7 as [UN], meaning “Modules must not connect to this pin if using this socket type.” (

I’d appreciate feedback from somebody on why this won’t cause a conflict with other pins?


It will be used when connect to a K socket and ignored on a U socket

Excellent. Would be great if somebody could add that to the documentation. Having the additional “K” (hardware flow control) available as an option is useful information.
