Companion Sheild
The entry level shield is labelled The Companion Shield. This is a PCB laid out in the pattern of a solderless breadboard. The holes are single sided, which means that components can easily be removed using solder mop braid, or a solder vacuum tool, if a mistake is made, or components need to be re-used.

Re: SERIN2 Receiving Wrong Data
I guess then, the sending device is interrupted by the USB routines while sending and as a consequence the transmission of RS-232 at that time is corrupted.
