Remarkable improvement of performance, multiple features without compromises
FITLET3 outperforms former Atom-based platforms in almost every aspect: CPU performance is up to x1.7 better, graphics performance is up to x2 better, and storage performance is up to x7 better.
Our FITLET3 is pre-configured with the extention below:
- Terminal block w/ RS-232, RS-485, GPIOs.
- TPM | On-board Trusted Platform Module assembled on SBC.
- On-board Intel AX210 WiFi/BT, including antennas and panel.
The custom-made FITLET3 motherboard was designed to fully utilize the capabilities of Intel’s most advanced Atom platform, allowing up to 32GB, 3200MT/s DDR4 memory, and a comprehensive set of communication and industrial interfaces.
Additional interfaces are optional using one of the 3rd generation FACET extension cards:
- FC3-LAN: Two more 1Gb Ethernet ports to a total of four ports on RJ45 connectors
- FC3-OPLN: 1GbE over SFP+ for optical LAN
- FC3-POED: a single 1Gb PoE Ethernet port that can power the fitlet3
fitlet3 is aimed at industrial automation, AI edge computing, and IoT applications. Therefore, it was designed with a full range of capabilities and features to bring outstanding value in any scenario.
The following properties make the fitlet3 ideal as an industrial control system, an AI Edge computer, or an IoT gateway:
- Small, Fanless, rugged housing
- Industrial temperature range availability: -40°C to 85°C
- Wide voltage input range of 7V to 42V
- Extensive wired and wireless connectivity
- Isolated COM ports and GPIOs
- Secure boot and TPM 2.0
- 5 years warranty and 15 years of availability
How to customize the FITLET3
There are over 1000 different ways to customize the FITLET3. You can also request additional customizations such as flashing, software support, housing modifications, and more! Please follow the steps below to fully customize your FITLET3
STEP 1: Choose a processor
The FITLET3 is available in 3 different CPUs, 2 core or 4 core. Please contact our team if you need help choosing the CPU.

Intel Atom® x6425E Processor (4 Core)
The Intel Atom x6425E has 4 cores with 4 threads and is based on the 6. gen of the Intel Atom series. The processor uses a mainboard with the BGA 1493 socket and was released in Q1/2021.

Intel® Celeron® Processor J6412 (4 Core)
The Intel Celeron J6412 has 4 cores with 4 threads and is based on the 11. gen of the Intel Celeron series. The processor uses a mainboard with the BGA 1493 socket and was released in Q1/2021.

Intel Atom® x6211E Processor (4 Core)
The Intel Atom x6211E has 2 cores with 2 threads and is based on the 6. gen of the Intel Atom series. The processor uses a mainboard with the BGA 1493 socket and was released in Q1/2021.
STEP 2: Pick memory and storage
The FITLET3 supports up to 32GB Memory.
Storage: NVMe M.2 + SATA M.2 or 2.5” SSD/HDD (up to 2 devices)
NVME M.2 SSD: Recommended as a first storage device.
M.2 SATA Storage: Recommended as a secondary storage device
Note: choose a storage device to enable OS selection

STEP 3: Pre-installed operating system
Windows 10 IoT Enterprise LTSC 2021
Windows 10 Pro
Windows 11 Pro
Linux Mint/ Ubuntu
Compatible with other hypervisors and operating systems (e.g. ESXi, FreeBSD)
STEP 4: Add extra function/ports
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). This way its possible to add extra RJ-45 ports, Wifi extentions, and 4G/5G functionality.

FC3-LAN:
Additional two 1GbE ports, for a total of four GbE ports

FC3-POED:
GbE LAN PoE device on RJ45

FC3-OPLN:
GbE on SFP+ for optic LAN
STEP 5: add LTE/5G/4G
On-board module with Wi-Fi 6E, BT 5.
Optional M.2, LTE/5G modem, with micro-SIM tray
STEP 6: Dertermine the temperature
FITLET3 is the first miniature PC by Compulab able to operate at the full industrial temperature range of -40°C to 85°C. The standard temprature range is 0°C to 50°C.
