Default GB still open?

Is the group buy still open?

And is there any indication on pricing ?

Thanks!

For the group buy go here. Pricing was quoted some time ago for fewer boards and still a slightly different layout. It was very reasonable.

Default Ask

Hi all, new member here.

I want to ask, is it okay to use resistors which is valued +/- 5% on its original value in this project? Because i have some resistors (metal film) with uncommon values, such like:
464 ohms --> substitutes the 470
215 ohms --> substitutes the 220

I want to build this thing too. But since i'm a really little poor guy now, i dont have much budget. I want to use as many components that i already have

Thanks before.

Hi,
+-1% resistors are close tolerance.
Most circuits will operate with +-5% tolerance.
The B1 will work with this wider tolerance.
