Extensions

Function and Connectivity Extension T-Card (FACET card) interface
Available FACET cards:

  • FC3-LAN – 2x GbE LAN on RJ45
  • FC3-POED – GbE LAN PoE device on RJ45
  • FC3-OPLN – GbE on SFP+ for optic LAN
  • EB-M2SATA – SATA expansion for 2.5” HDD / SSD

FACET Card interface includes 2x PCIe, USB and I2C.
Additional FACET cards are under development.
FACET expansion card and Wi-Fi/BT card are mutually exclusive. For Wi-Fi/BT on systems with FACET cards, an onboard Wi-Fi/BT module must be selected.

1 Up to 1 unit of EB-M2SATA is possible, and up to two storage devices in total.
2 EB-M2SATA expansion requires deep bottom that will enlarge the fitlet3 size.

Operating
conditions

Power

Input voltage range
DC 7V – 42V

Power consumption
5W – 25W

Power consumption depends on
– CPU type
– System load
– Installed devices
– Connected peripherals

Note:

fitlet3 is low power Class III (EN/IEC 62368-1 Audio/video, information and communication technology) equipment that is to be powered from external DC Low Power  (LPS) unregulated power supply. The external power supply ratings and unregulated voltage boundaries should comply with ones defined in specifications of the specific model. Nominal current rating (A) should be increased if external peripheral devices are to be powered by fitlet3. Compulab delivers fitlet3 with a general purpose 12V 3A  AC-DC power adapter that isn’t an integral part of fitlet3 and may be ordered separately as an accessory. In case fitlet3 is powered from another power supply, user should ensure that power supply complies with fitlet3 power requirements. The power connector should meet the following requirements: a. 5.5 x 2.5mm standard barrel, b. Inner contact – fork type, c.“+” inner contact, “-” outer contact

Temperature
& humidity

Operating temperature range
Up to -40°C to 85°C*

Relative humidity
5% – 95% non-condensing

* When ordered in industrial temperature range. Commercial and extended temperature range are also available. The power supply that ships with fitlet3 is not rated for extended temperatures. Buyer is advised to deploy fitlet3 in extended temperature with a suitable power supply.
