There are many good reasons for a Fitlet3

nesevo is your global Fitlet reseller.  


Just under 133 mm X 100 mm X 35 mm, with advanced heat transfer and dissipation from internal components.
Rigid, durable, fanless housing for harsh environments. The main advantages over the Fitlet2 are the much higher CPU performance and the doubled maximum RAM limit.

Utilizing a quad-core Atom processor with unconditionally-efficient heat dissipation, the high performance remains consistent. With up to 32GB of DDR4 memory at a speed of up to 3200MT/s, the processing capabilities are comparable to what’s expected from much larger, more power-consuming, and less affordable computers.
