The Axiomtek ICO300 is a compact fanless embedded computer for communication control, protocol conversion, SCADA, and industrial automation. Configurations use an Intel Atom E3815 or E3827 processor and provide four selectable RS-232/422/485 ports, two isolated Gigabit Ethernet ports, VGA, USB 2.0, and 12–24 VDC input. The observed ICO300-E3827-PB-DC configuration is the E3827 1.75 GHz power-button version cataloged as Axiomtek P/N E22C300110
Configurations vary. Verify the exact unit before choosing a replacement.

Windows 7 Embedded, Windows 8 Embedded, Windows 10 IoT Core Pro, and Linux support package; an operating system is not established as universally installed
What Does ICO300 Mean?
The archived configured identifier can be interpreted from Axiomtek's ordering table and variant terminology without extending those details to every ICO300.
Segment
Field
Interpretation
ICO300
Product family
Axiomtek DIN-rail fanless embedded-system family
E3827
Processor
Intel Atom E3827, 1.75 GHz
No DIO segment
Digital I/O option
The exact 2021 ordering row is the four-COM version without the DIO designation; DIO configurations include a DIO segment
PB
Control option
Power-button chassis variant; the manual identifies power-button units as ICO300-PB
DC
Power suffix
The documented order code includes DC and the product uses 12–24 VDC terminal-block input; Axiomtek does not provide a separate suffix legend in the cited documents

Catalog part number associated with ICO300-E3827-PB-DC
Configuration Boundaries
ICO300 does not encode a universal installed memory, storage, wireless, or DIO configuration.
Digital I/OPresent on ICO300-DIO configurations; it must not be asserted for an identifier lacking the DIO segment without physical evidence.
CompactFlash and mSATAThe platform supports either CompactFlash or mSATA selection, not both simultaneously.
mSATA and wirelessThese functions share the expansion resource and are mutually exclusive.
Installed media and memoryCapacities are separately selected options and are not established by ICO300 alone.

Document Revision Note
The April 2021 datasheet explicitly catalogs ICO300-E3827-PB-DC as P/N E22C300110. A September 2025 revision at Axiomtek's primary datasheet endpoint instead lists E3815-B and E3827-B ordering codes. The newer codes do not invalidate the historical identifier, but the documents do not establish a direct replacement relationship.
