3.5-inch SBC expands upon Tiger Lake-U with 2.5GbE and quad displays

Sep 28, 2021 — by Eric Brown 457 views

MiTac’s 3.5-inch “PD11TGS” SBC is equipped with an 11th Gen U-series CPU with quadruple display support plus 2.5GbE, GbE, 4x USB 3.2 Gen2, SATA III, and M.2 E-key and B-key slots with nano-SIM.

ICP Germany has begun distributing what appears to be MiTac’s first 3.5-inch SBC. The 3.5-inch form-factor PD11TGS board follows MiTac’s MP1-11TGS embedded system, which similarly runs on Intel’s 10nm-fabricated, 11th Gen Tiger Lake ULP. Other Tiger Lake-U based 3.5-inch boards include Commell’s LE-370, among others.

The PD11TGS defaults to a dual-core, 1.7GHz/3.9GHz Core i3-1115G4E, but also supports other Tiger Lake-U Core processors up to an i7-1185G7E. The Celeron 6395E is also available. Win 10 is standard and Ubuntu 18.04 with Linux Kernel 4.15 is available by request.

Tiger Lake-U is the original low-power 11th gen Core line, compared to the later, up to octa-core Tiger Lake-H. Highlights include a 12-28W configurable TDP, Intel Time Coordinated Computing (TCC) and much improved Iris Xe graphics. You also get 5x times the AI power of earlier Core CPUs, drawing on both CPU and GPU.


Like the LE-370, the PD11TGS supports up to 32GB DDR4-3200 rather than the 64GB limit on some 11th Gen 3.5-inch entries, such as Kontron’s 3.5”-SBC-TGL and Aaeon’s GENE-TGU6. The PD11TGS is equipped with SATA with power plus 2.5GbE, GbE, and 4x USB 3.2 Gen2 ports. There are also internal serial and USB 2.0 ports and M.2 E-key and B-key slots with nano-SIM and optional 5G.

Quadruple independent displays are available via a DisplayPort at up to 5120 x 3200 @60Hz and dual HDMI ports, which MiTac variably lists the as providing up to 3840 x 2160 @30Hz or up to 4096 x 2160 @60Hz. There is also an LVDS interface that can be swapped out for eDP, and the detail view suggests you can optionally express the eDP as a second coastline DisplayPort.

The ICP press release lists a 0 to 60°C operating range while the spec sheets say -40 to 50°C or 60°C, depending on the TDP. The announcement also mentions an ICP bundle with “industrial RAM and storage medium.” The system has a wide-range input and TPM 2.0.
