Crystalline Electronic Unit
The Crystalline Electronic Unit is an upgrade material in Arknights, introduced alongside Episode 08.
Usage[edit]
The third of the Crystalline-type upgrade materials, Crystalline Electronic Units are an electronic control unit that integrates a Crystalline Circuit and used as one of the major components of advanced Originium-based electronic devices in Terra, from high-performance Arts catalysts to mainframes and supercomputers. Crystalline Electronic Units are required for the skill Specialization training and Elite 2 promotion of certain Operators introduced from Episode 08 onwards.

Trivia[edit]
- Before the Who is Real update in the Global server, the material was named Crystalline Electroassembly.
- The Crystalline Electronic Unit is currently considered the hardest material to acquire by the Arknights community because:
- It is the first T5 upgrade material that is part of an upgrade material type (Crystalline).
- Excluding
Bipolar Nanoflake, which only requires two types of materials, the Crystalline Electronic Unit is the first T5 upgrade material that requires two of a particular T4 material (in this case, two 
Polymerized Gel) to produce one.
