NANO-ITX industrial motherboards
The square NANO standard between a credit-card SBC and Mini-ITX. Five models scale from a 6W fanless N100 to Core Ultra 125H or 155H with DDR5-5600, up to four LAN ports with PoE, and DB9 serial on the rear panel.
01 · Why 120 × 120 mm
Square, panel-friendly, network-ready.
120 × 120 mm sits between the credit-card SBC and Mini-ITX. It keeps panel mounting options while adding the ports a gateway or panel PC needs.
