Rugged Bay Trail Pico-ITX SBC has multiple expansion paths

Aug 27, 2015 — by Eric Brown 768 views

Advantech’s COM-like “MIO-3260” Pico-ITX SBC runs Linux on a Bay Trail SoC and offers a PCIe/mSATA slot, MIOe expansion, and optional -40 to 85°C operation.

Like Advantech’s MIO-2263, which was announced in May, the MIO-3260 is a 100 x 72mm Pico-ITX board that supports a quad-core Intel Celeron or dual-core Intel Atom from the 22nm Bay Trail generation. Like the earlier, Atom Cedarview generation MIO-2262, the MIO-3260 lacks real-world ports, thereby acting as much like a computer-on-module as a single board computer.

The port-free design lets you use it without the optional MIOE-DB2100 baseboard (see farther below) and directly slot it into embedded devices like a COM. The product is aimed at “super slim, cableless, or rugged” designs including panel PC and outdoor applications, industrial control, medical portable devices, point of sale, and home automation,” says Advantech.

Interfaces are expressed via a pair of 64-pin connectors as well as the company’s modular MIOe expansion connector. The MIOe interface offers additional I/O including PCIe, USB 3.0, and DisplayPort/HDMI, which is supported in dual display configurations along with the onboard VGA and LVDS interfaces.


There’s also a mini-PCIe slot that’s equipped with PCIe, USB, and SATA signals, enabling its use with either mini-PCIe or mSATA modules. In yet another wrinkle in this complex product, two of the six available models, half of which support an industrial -40 to 85°C temperature range, replace one of the two 64-pin connectors with box wafer interfaces, as indicated below.

Here’s the MIO-3260 lineup in a nutshell:

  • MIO-3260L-S3A1E – Atom E3825, 2x 64-pin I/O, 0 to 60°C
  • MIO-3260L-S8A1E – Celeron N2930, 2x 64-pin I/O, 0 to 60°C
  • MIO-3260C-S8A1E — Celeron N2930, 1x 64-pin I/O with 1x box wafer I/O, 0 to 60°C
  • MIO-3260LZ22GS3A1E — Atom E3825, 2x 64-pin I/O, -40 to 85°C
  • MIO-3260LZ22GS8A1E — Celeron N2930, 2x 64-pin I/O, -40 to 85°C
  • MIO-3260CZ22GS8A1E — Celeron N2930, 1x 64-pin I/O with 1x box wafer I/O, -40 to 85°C

The MIO-3260 offers a choice of a 1.33GHz, dual-core Atom E3825 with a 6W TDP, as well as a quad-core, 1.83GHz Celeron N2930, which has a lower 7.5W TDP than the Celeron J1900 found on the MIO-2263. Up to 8GB of RAM is available on all the models, according to the spec sheet, although the industrial temperature models are also said to ship with “2GB bundled” so those boards ship with the SODIMM pre-installed. Even without shelling out for any MIOe expansion cards, you get I/O including GbE, SATA, four USB 2.0, dual RS-232/422/485, HD audio, and GPIO.

The MIO-3260 has a 12V DC power hot plug protection design, and an optional MIO/e module provides a 5Vsb/12Vsb power supply “for power-exchange processing which offers a higher throughput yet consumes less power, and can integrate existing data without sacrificing software compatibility,” says Advantech. The total height with heatsink is 25.8mm, which is said to meet the requirements for slim chassis applications. Long life cycle support is offered until 2020.

MIOE-DB2100 carrier board

Advantech provides an optional 165 x 115mm EPIC form-factor “MIOE-DB2100” carrier board for the MIO-3260 that has a cut-out for the SBC, presumably in order to avoid adding height in a sandwich-style configuration.
