Adding pull-ups/downs to Beijing

Got a great tip from a customer (Maarten Zanders in Belgium) for the Beijing module. His words below.

Here’s a tip for if you use Beijing to process buttons. If you want to add stronger pull-ups (the PIC’s internal pullups are too weak to be used on physical -long- wire), there’s a component from “the old days” that can help you out: SIL resistor arrays.

Picture attached shows the resistor array in place. I think this position results in a pull down configuration.
I only have the 10 pin version at hand (9 pull-ups) but 11pin versions also exist.
