Hello all.
I've recently purchased one of these kits from AliExpress (red board, SCM ATMEGA328P DIP-28, 160x128 pixel 16 bit color display, etc.) and am in the process of ensuring it is good to go before constructing the board. However, in the docs from
www.mikrocontroller.net/ it recommends the following:
The resistors R1 to R6 are critical for measurements and this 680 and 470k resistors should be measurement type resistors (tolerance of 0.1%) to get the full accuracy.
The kits resistors are all bog standard 1% type. I've been to the local Altronics store and search Jaycar online and can't find these low tolerance components. I've searched the forum here for advice on sourcing these components, but had no luck (me or the search function? Who can say!).
Can anyone point me in the right direction to find suitable components? Given I only need a small number and from what I can see from online suppliers (Element14, Mouser, etc.) the parts will be worth close to the value of the rest of the unit!
Many thanks.
