fitlet2
frequently asked questions

No. It supports M.2 storage devices with SATA interface, but not NVMe devices.

Best to consult Anandtech on video playback capabilities.

* This is the same Celeron J3455 used in fitlet2/MBM2

fitlet2 ships with a universal 100V – 240V PSU and a full international AC plugs set.
It should work worldwide out-of-the-box.

Please consult owner’s manual for more details.

FC-CEM and FC-PCI essentially provide the same functionality:
1. Cellular modem incl. micro-SIM
2. WiFi card
3. M.2 SSD up to 2280

Since miniPCIe and M.2 modems are both popular there is a version that supports each respectively, hence the two FACETs.

fitlet2 is based on Apollo Lake which is one of the CPUs identified by Intel to be vulnerable to INTEL-SA-00086

Compulab applied the Intel recommended update as soon as it became available.

fitlet2 units shipped after 23-Nov-2017 are not subject to the vulnerability.
To update fitlet2 units purchased earlier please contact support@fit-iot.com

You may consult minimum requirements defined by the application vendor.

You may also check user-reviews of platforms having similar CPU, e.g. Intel NUC NUC6CAYH. Performance of fitlet2 J3455 is nearly identical.

fitlet2 supports integrating either mini-PCIe or M.2 cellular modem. (of course, an external USB modem is also an option).

To use a cellular modem inside fitlet2 a FACET card is required.

  • FC-CEM for M.2 modem. micro-SIM socket is on the FACET itself. The modem is inserted into the B-key M.2 socket.
    WiFi M.2 adapter is supported and can work in conjunction with the cellular modem.
    M.2 2280 SSD can be installed.
     
  • FC-PCI for miniPCIe modem. micro-SIM socket is on the FACET itself. The modem is inserted into the miniPCIe socket.
    WiFi M.2 adapter is supported and can work in conjunction with the cellular modem.
    M.2 2280 SSD can be installed.

Compulab can supply an LTE or 3G miniPCIe modem for FC-PCI.

Not necessarily.
Compulab performs stress-tests on industrial temperature (TI) rated systems to qualify the system with the installed components. This test is more reliable than the testing of individual components.

Yes. Z-Wave adapters are available in mini-PCIe form factor.

Any mini-PCIe card can be installed using the FC-PCIe FACET Card.

fitlet2 has a single SATA interface and supports a single SATA device.

Extra storage devices can be connected through USB / micro-SD.

 

Vanilla fitlet2 can take M.2 M-key 2260 / 2242 SATA SSDs.

Some FACETs (like FC-LAN, FC-USB) do not interfere with the SSD.

Some FACETs (like FC-CEL, FC-PCIe) allow installing M.2 M-key 2280 SATA SSDs.

 

Apollo Lake architecture supports dual channel, but there is no performance penalty in using single channel (unlike Core CPUs, where dual channel improves performance).
There is also no RAM capacity restriction. In fact fitlet2 supports 16 GB RAM rather than 8 GB max as stated for Apollo Lake.

fitlet2 does not support ECC RAM. In DDR3 SODIMM ECC RAM requires a different pinout than non-ECC RAM.
