Fitlet & MintBox


Compulab's Fitlet and Fitlet2 are tiny fanless PC's designed for IoT and field operations.

Fitlet2 is a unique Fanless micro-sized PC powered by dual and quad core Intel Apollo Lake processors. With the latest technology, extreme reliability, enhanced flexibility and low power consumption, Fitlet2 is a beautifully designed PC for 24/7 data collection, monitoring and processing applications and has the option to withstand a wider range of operating temperatures (-40/+85C). (See configuration options) 

Not only Fitlet2 is your perfect process control unit for embedded CCTV systems and industrial supervision, it is also the optimal IoT gateway for smart building, transportation and real-time data management thanks to Atom Apollo Lake processors, especially developed for the IoT world.

fitlet2 is an affordable miniature Apollo Lake PC for demanding IoT applications

MiniDis announces immediate availability of fitlet2. Based on Intel Atom® x7-E3950 Processor (Apollo-Lake) with up to 16 GB RAM and storage options ranging from eMMC to 2.5” SSD, fitlet2 is one of the most versatile miniature PCs for IoT. fitlet2 functionality can be further extended with Compulab 2nd generation Function and Connectivity Extension T-Cards (FACET Cards).

Like all other Compulab mini-PCs, fitlet2 is completely fanless, available at wide temperature range and is sold with 5 year warranty.

Miniature fanless design

fitlet2 measures only 112 mm by 84 mm, making it one of the smallest full-featured PCs on the market. An all-metal die-cast housing is used for fanless passive heat dissipation. There are several optional versions of the housing including low-profile 25mm and an industrial top cover for direct-mounting.


“IoT gateways have to be small, affordable and reliable” said Irad Stavi, Chief Product Officer at Compulab. “Furthermore, each IoT application requires a slightly different set of features. The most effective way to meet this requirement is by integrating an application-specific module into the gateway. fitlet2 achieves this flexibility with FACET cards.”

Compulab developed several FACET Cards for fitlet2, including:

    FC-LAN with two additional Gbit Ethernet cards (for a total of four).
    FC-PCIe and FC-CEM with support for both 4G cellular modem and WiFi that together with dual Gbit Ethernet makes a capable miniature IoT gateway.
    FC-USB adds 4 USB ports for a total of 8.

Additional FACET cards are under development, including FACET making filtet2 a PoE powered device, a FACET for integrating 2.5” HDD/SSD and a FACET for optical LAN.
Compulab supports solution providers and 3rd parties in designing their own FACET cards. FACET specifications and reference designs are public.


fitlet2 is based on Intel Apollo-Lake SoC. Off-the-shelf it is offered with E3950 / E3930 / J3455. Other CPU variants are available for volume orders. The CPU is supplemented by DDR3L-1866 SODIMM at capacity of up to 16 GB.
fitlet2 has broad selection of modular storage devices including M.2 SATA SSD, modular eMMC card or 2.5” HDD/SSD.
Wired networking is implemented by 2 to 4 Intel I211 Gbit Ethernet ports. Wireless networking includes modular WiFi adapter and 4G cellular modem adapter that can be installed together.
fitlet2 supports dual-head 4K displays. Other I/O includes 4 to 8 USB ports incl. 2x USB 3.0, audio line-out, line-in and S/PDIF, a serial port and micro-SD socket.

Designed for IoT

fitlet2 is designed from the ground-up to meet present and future IoT requirements. It features the following IoT related properties:

    5 year warranty and 15 years availability
    Operation in full industrial temperature range of -40°C to 85°C
    Shock, vibration, dust and humidity resistance
    Input power tolerance of 8V to 36V DC
    Automatic boot on power resume (auto-on)
    BIOS settings are saved to flash memory. fitlet2 can work without an RTC battery
    Power button disable and remote power-button connector
    Optional TPM

fitlet2 has multiple mounting and deployment options, including VESA and DIN-rail mounting, direct mounting with thermal coupling and an SBC model. This flexibility together with the inherent small footprint simplifies integration of fitlet2 in nearly any scenario including automotive, transportation, utility, industrial, retail and supply-chain IoT applications.
