Nano-ITX embedded computer boards

Portwell has chosen Intel Core 3 Processor N355 to be the CPU behind a series of 120 x 120mm Nano-ITX embedded computer boards for edge computing, automation and signage.

Sharing the same NANO-6065 series name, there are two other boards: one with a Processor N150 and the other with an Atom x7835RE.

“Its processor options allow system designers to tailor the balance between performance and power efficiency,” the company said.


All three can accept up to 16Gbyte of ram in a single DDR5 SO-DIMM, for which in-band ECC is supported.


For non-volatile memory there is a SATA III connector and a Micro SD socket, and beyond these an M.2 E key 2230 slot (USB, PCIe) and an M.2 B key 3052/2280 slot (USB, PCIe, SATA 4G/5G).

To go with the B Key slot when it is used for cellular communication, a nano SIM slot is provided for wireless access.

The main high-speed external interfaces are dual 2.5Gbit/s Ethernet ports and up to three displays are handled by two HDMI 2.0B ports (4,096 x 2,160, 60Hz) and DisplayPort Alt (1.4) via a USB Type C connector (4,096 x 2,304, 60Hz). An optional LVDS connector can be included as an option if sufficient boards are ordered.

Three USB 3.2 Gen2 Type A ports are provided for general use, and for industrial users there are RS-232/422/485 serial ports, and GPIOs for direct signalling.

Security hardware includes built-in TPM 2.0.

On-board hardware monitors voltage, fan speed and temperature, and a programmable watchdog can be set between 500ns and 250s.

Power is needed at between 12 and 24V through a four-pin ATX connector.

Earlier this year, Aaeon put a Core 3 Processor N355, with an N150 option, on a 85.6 x 90mm motherboard
