The Jetway B420PADN1 is a compact, fanless box PC built around an Intel N97 or N200 Alder Lake-N SoCs. The computer system features a Pico-ITX motherboard and operates in a wide -20°C to 50°C temperature range for industrial, commercial, and embedded applications where reliable and silent operation are important.
The PC comes pre-installed with 8GB DDR5 4800MHz SO-DIMM memory (expandable up to 32GB) and supports 4K display output via an HDMI 2.0b port. For storage and expansion, it offers M.2 B+M Key and E-Key slots, along with a Nano SIM slot for cellular connectivity. Other features include two serial ports, USB 3.2 Gen1 and USB 2.0 ports, Gigabit Ethernet, and VESA/wall mounting options. These features make this embedded box PC suitable for applications such as digital signage, industrial automation, edge computing, IoT gateways, kiosks, and smart retail.

The company mentions that the B420PADN1 fanless compact box PC features a SIM card (as listed in the specs), but I could not find any SIM slot on the PC itself. That’s because it’s inside the computer. I know that because the B420ADN1 is based on the Jetway JPIC-ADN1 Pico-ITX SBC we covered last year…
The PC supports Linux, Windows 10, and Windows 11. You’ll find the drivers, BIOS, and user manuals in the download section of the product page (linked below).
The B420ADN1 ships with a wall and VESA mount kit, a screw pack, and a lockable 12V/3.3A 40W adapter for power. Additionally, there’s a region-specific power cord and pre-installed 8GB DDR5 4800MHz memory.
The company does not usually release pricing information publicly. Additional information about the B420PADN1 can be found on the product page. Alternative embedded computers based on the Intel Alder Lake-N family include the relatively compact UP Squared 7100 Edge fanless mini PC, and if your application requires more features and ports, you can have a look at systems like the AAEON BOXER-6406-ADN or Cincoze DC-1300.

Have confirmed that 64GB DDR5 SODIMM is working nicely with other Alder Lake N-based SBC, the Odroid H4 series.

I didn’t even know those existed.
Compact us a lie unless they show how large the power brick is. Some of these Chinese makers have seen the light and are powering them with USB-C PD.
