IOT-GATE-APL (Fitlet2) is a unique Fanless micro-sized PC powered by dual and quad core Intel Apollo Lake processors. With latest technology, extreme reliability, enhanced flexibility and low power consumption, IOT-GATE-APL (Fitlet2) is a beautifully designed PC for IoT applications..

IOT-GATE-APL (Fitlet2) is 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. With extensive connectivity options and optional application specific FACET (Function and Connectivity Extension T-Cards) modules can be installed.

Best Designed Apollo Lake Micro PC 

IOT-GATE-APL (Fitlet2) is the best engineered IoT PC in the market. This gateway PC is built around Atom E3950 Apollo Lake processors which have been especially developed by Intel for industrial IoT applications, bringing improved data communications and faster processing tasks thanks to 64-bit quad-core CPU performance in a case as small as 112 x 84 x 34 mm.

Micro PC Fitlet2

Built-in heat sink version measures 112 x 84 x 34 mm and offers new cooling fins for optimal heat dissipation.

On top of this, you add rich customisable connectivity and best-in-class reliability and you get the perfect micro-sized PC for fire alarm systems, building security, remote diagnosis, predictive maintenance or fleet monitoring.

Intel Atom Apollo Lake or Celeron Processors

The CPU at the heart of the PC is crucial. We offer you quality and flexibility with 3 types of processors. For fast data communications and processing needs, two quad-core processors are available. The E3950 is based on the Intel® Atom™ Processor x7 Series with 4 cores, a CPU speed range of 1.6 to 2 GHz and low power consumption from 5W. A processing performance that not long ago could not be fitted in such a small passively-cooled footprint due to higher power consumption.

Geekbench3 score for J3455 is 4700

Alternatively, the J3455 comes with the Intel® Celeron® Processor J Series, also has 4 cores, a CPU speed range of 1.5 to 2.3 GHz. For low processing performance requirements, a dual-core Intel® Atom™ Processor x5 Series option (with E3930) is available on demand. All models come with outstanding graphics capabilities through the Intel® HD Graphics 505/500 processors.

24/7 Reliability & Energy-Efficiency

With no moving parts, Fanless technology ensures the best resistance to cold or dusty environments. However, thermal design has been enhanced with new cooling fins and built-in heat sink, enabling the PC to support a wider operating temperatures range of between -40 and +85C.

Energy efficiency has been improved with a low power consumption of 5W-15W (depending on CPU type, system load, devices and peripherals). We can help you test and estimate power consumption and CPU TDP configuration. Thanks to M.2 mSATA, note that the booting time and the energy efficiency of the storage have improved. Selectable power source (15-36V) is also available.

Rich Standard Connectivity, Expandable via FACET

Versatility is impressive on IOT-GATE-APL (Fitlet2). Standard connectivity already packs comprehensible features with dual Ethernet ports, dual 4K video outputs (appreciable for CCTV and inspection applications), 1x microSD card slot, 1x serial port, 2 GPIO LED, 2x USB 3.0 ports and 2x USB 2.0 ports.

On top of that, the Function And Connectivity T-card (or FACET card) provides further customisation choices such as additional

  • Dual Gbit Ethernet
  • 4 extra USB 2.0 ports
  • mini PCIe + Micro SIM + M.2 E-Key + M.2 M-Key 2280
  • M.2 B-Key + Micro SIM + M.2. E-Key + M.2. M-Key 2280
  • eDP 1.3 and I2C
  • plus PoE, Optical LAN and more in development

Enabling customers to configure the Fanless PC for their specific needs.

RAM options go from 2GB to 16GB. Don’t be surprised to find 16GB. This is very impressive for a form factor this small, and against all other PCs with x7 E3950 or J3455 in the market, like the NUC version, which are commercialised with up to 8GB.

Note that, with latest storage technology (M.2 mSATA), the booting time and the energy efficiency of the storage have improved.
