This mod adds some new modules for your armor for upgrade your inventory size, your health and your mining, crafting speed and more! (Requires Better Power Armor Grid for work: https://mods.factorio.com/mod/Better-Power-Armor-Grid).
Changelogs:
-1.1.0:
Fixed compatibility with the library.
-1.0.0:
Released! Speeeeeeeeeeeeed!

This mod is not projected for my FactorioPlus mods, however you can use it if you want with them (i'll probably integrate this one with them as a addon).

Spoiler: All the modules are infinity stackable! (if you stack a lot of toolbar modules, you will be surprised XD!)
