NERMAL v1.1

Build Guide

Congratulations on your decision to build a Nermal module! Nermal is a
fairly easy build with a moderate component count, but please go
through this guide at least quickly to make sure you’re not missing
anything.

Important!

DO NOT EMPTY ANY OF THE COMPONENT BAGS NOW! The components are grouped
into the bags so that all of them can be identified without having to
look up resistor ring codes. Rather leave everything inside the bags
and take out what you need while soldering.
