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: Framing error if I disable transmitter after shift register is empty?
Since the output on that specific chip will remain as driven output, and if you insist on using this, a crapy solution maybe to add a diode at the output before the pin is connected to the bus.
