Intro
The Caterium Branch in the MAM provides access to power and electronic technologies. Starting off with 10 Caterium Ore you'll unlock the ability or scan for Caterium Ore using the V key. Researching with another 50 Caterium Ore gives the ability to craft Caterium Ingots on the Craft Bench or Smelter.
Quickwire
Once you have 50 Caterium Ingots you can then research Quickwire which unlocks the ability to craft Quickwire on the Craft Bench or Constructor as well as getting access to Lights in the AWESOME Shop.
Zipline Tool
At this point multiple research branches open up starting with Zipline. 100 x Quickwire and 50 x Cable unlocks the Zipline tool which you create in the Equipment Workshop. Once place in a hand slot you are now able to travel along power lines, either by holding the left mouse button down to grip the power line or right clicking once to make ziplining automatic. You'll still need to jump around power poles while ziplining. In Tier 4 of the Hub, unlocking Expanded Power Infrastructure makes ziplining between power towers is seemless without jumping. Don't forget to hold SHIFT down while ziplining to go faster, something I always forget.
Stun Rebar
Stun Rebar is available for research with 50 x Quickwire and 10 x Iron Rebar, providing the ability to craft Stun Rebar in the Equipment Workshop or Assembler. Stun Rebar is a very effective ammunition for the Rebar Gun, stunning a hostile for a short time which allows you to get up close and attack with a close range weapon.
Power Poles & Connectors
Caterium Electronics is the next branch to unlock requiring 100 x Quickwire, exposing more research branches. Immediately underneath you can unlock Power Poles Mk.2 with 300 x Quickwire and this also unlocks Wall Outlets Mk.2 in the AWESOME Shop, these both allow 7 power connections. Underneath again is Power Poles Mk.3 with 50 x High-Speed Connectors and 200 x Steel Pipes, also unlocking Wall Outlets Mk.3 in the AWESOME Shop, these both allow 10 power connections.
AI Limiter
To the left is AI Limiter, unlockable with 200 x Quickwire and 50 x Copper Sheet. With this you'll be able to craft AI Limiters in the Craft Bench or Assembler. AI Limiters are used in later recipes and other buildables like the Smart Splitter.
Smart Splitter
The Smart Splitter is unlocked with 10 x AI Limiter and 50 x Reinforced Iron Plate. The Smart Splitter is now a buildable item that allows you to direct materials to output belts and this can be specific or based on a belt needing to overflow. This is covered in more detail in my Smart / Programable Splitter and Overflow article on the Satisfactory Guru Website.
Power Switch
The Power Switch can be unlocked with 100 x Steel Beams and 50 x AI Limiters. The Power Switch is now a buildable item that allows you to separate two power lines controlled by the switch, allowing you to isolate a section of machines and power them on or off when required. This can be useful when your available power is limited and you want to stop the production of certain products.
High-Speed Connector
On the right is High-Speed Connector, unlockable with 500 x Quickwire and 50 x Plastic. With this you'll be able to craft High-Speed Connectors in the Craft Bench or Manufacturer. High-Speed Connectors are used in later recipes and other buildables like the Power Pole Mk.3.
Priority Power Switch
The Priority Power Switch can be unlocked with 25 x High-Speed Connectors and 500 x Quickwire. The Priority Power Switch is now a buildable item that allows you to define which sections of the power grid should shut off first in the event of a power trip occurring. You can also toggle other priority power switches on the grid remotely from within it's interface.
Homing Rifle Ammo
Bullet Guidance System can be researched with 10 x High-Speed Connectors and 500 x Rifle Ammo. This provides the ability to craft Homing Rifle Ammo in the Equipment Workshop or Assembler. Homing Ammo will accurately hit targets the Rifle is aimed at, however be careful as it may lock onto a Lizard Doggo, putting it to sleep permanently.
Programmable Splitter
The Programmable Splitter is unlocked with 100 x AI Limiters, 50 x Computers and 50 x Heavy Modular Frames. The Programmable Splitter is now a buildable item that allows you to direct materials on output belts and this can be specific or based on a belt needing to overflow. Multiple items can be directed on the same output making this more powerful than the Smart Splitter. This is covered in more detail in my Smart / Programable Splitter and Overflow article on the Satisfactory Guru Website.
Geothermal Generator
Last but not least is the Geothermal Generator, unlockable with 100 x High-Speed Connectors, 1,000 x Quickwire and 50 x Motors. Once researched you'll unlock the ability to scan for a Geyser using the V key and be able to build a Geothermal Generator on the Geyser. A Geothermal Generator generates 50-600 MW of free power depending on the purity of the Geyser it is placed on and this power will fluctuate. Those who want constant power graphs may not find the Geothermal Generators an attractive choice.
