fitlet2

The hardware and housing of fitlet2 are designed together from the ground-up to minimize size and maximize capabilities, durability and thermal performance.

fitlet2 measurements

fitlet2 measures only 112 mm by 84 mm.
It is one of the smallest full-featured PCs on the market.
The low-power models are only 25 mm thick.
The performance models are 34 mm thick.

fitlet2 is designed as a metal 3D jigsaw puzzle with interlocking parts.
Yet, it is very easy to take apart for installing RAM, storage and extension cards.

Surprisingly capable for its size

System
fitlet2 is based on quad-core Apollo-Lake Atom with up to 16 GB RAM.
It provides performance that not long ago required a Core CPU that could not be fitted in such a small passively-cooled footprint due to higher power consumption.

Extensions
Each IoT project is unique. A generic IoT gateway can rarely meet all special requirements.
That’s why fitlet2 is made modular – these extra requirements are implemented with an extension module integrated seamlessly into the housing. This module is called FACET-Card (Function And Connectivity Extension T-Card).

Compulab has a portfolio of often-requested FACET-Cards including:
● Extra Gbit Ethernet ports
● Extra USB ports
● 2.5″ HDD support
● 4G LTE modem in conjunction with WiFi
● Power-over-Ethernet device (PoE PD)
● More FACET cards are under development

The FACET-Card interface is public with already-designed FACET-Cards published for reference. This allows solution providers and 3rd parties to design their own custom FACET Cards.

Storage
fitlet2 supports the following main storage devices

● M.2 SATA provides high performance and large storage capacity
● 2.5″ HDD/SSD* is for extra capacity and for intensive write operations like video recording
● eMMC on an M.2 module is a low-cost storage solution for price-sensitive applications
The storage device is attached using specially designed M.2 cooling plate that dissipates heat through the housing.
*2.5″ storage device requires a special FACET card and raised bottom cover

Networking
Versatile networking is a key requirement for an IoT gateway. fitlet2 addresses this requirement with dual Gbit Ethernet ports (Intel I211) that can be extended to 4 ports and support for WiFi and 4G cellular modem working in conjunction.

Built tough

fitlet2 is designed with the failproof fanless cooling that Compulab pioneered and has been refining for over 10 years:
1. Make an all-metal housing that is thermally conductive, and design it for effective convection cooling
2. Thermally couple the hot-spots (CPU, SSD) to the housing
3. Use the housing as the heatsink

This design has several advantages over traditional cooling:

Warranty and longevity

Two major considerations in an IoT project are reliability and longevity. fitlet2 excels in both.
The embedded grade fanless design practically eliminates aging which allows us to provide unconditional 5 year warranty on fitlet2.
fitlet2 availability is 15 years. This ensures you will not have to redo integration, software adaptation and certification soon after completing the first cycle.

Mounting

fitlet2 is small enough to be easily and securely mounted in nearly any IoT scenario – in a cabinet, in a vehicle, inside a vending machine or just mounted behind a display, on the wall or on a furniture.
fitlet2 has the following mounting options:
including VESA and DIN-rail mounting.

Power supply

fitlet2 can work at wide input voltage range of 9V – 36V.
It can also be powered by a PoE FACET Card or be powered through a custom FACET card.
The DC-plug has a special twist-lock for preventing unintentional pull-out power loss.
Compulab provides auxiliary power solutions for fitlet2, including
● fit-Uptime miniature UPS
● Pig-tail cable (Y-cable) with twist-lock DC plug
