Industrial 5G Router (5G CPE) Reference Design
An illustrative reference design for an industrial-grade 5G router (5G CPE) at the access layer of the five-layer network architecture: an M.2 5G module for the cellular uplink, 4 Gigabit copper ports (WAN / LAN configurable), 1 isolated RS-485 port for field devices and a 9–36V wide-range input, with parts selected for the -40 ~ +85 °C wide temperature range. Each position is marked with the VOOHU parts available, recommended part numbers and package pinouts.
Illustrative PCB ⇄ Schematic
Illustrative top-side view arranged by functional zone (not the actual layout). Red numbered dots mark positions VOOHU can supply. Click a component on the board, an entry in the index below or a part in the schematic to see recommended parts and package pinouts on the right.
Illustrative 5G cellular topology: the M.2 5G module (J1) connects to the processor over PCIe or USB 3.x, with its 3.8V supplied by a dedicated wide-input buck; the UIM signals (CLK / IO / RST / VCC) of VOOHU Nano SIM socket J2 are protected by VOOHU ESD array D1 before reaching the module. Antennas attach externally via the module's RF connectors and are not drawn; high-speed differential pairs are drawn as 1 line per pair; series resistors and decoupling are not drawn.
