52Pi’s CM4 Router Board Offers the Raspberry Pi Compute Module 4 Twin Gigabit Ethernet Ports

52Pi, greatest identified for its modern cooling gadgets for the Raspberry Pi household of single-board computer systems, has launched a provider board for the Raspberry Pi Compute Module 4 (CM4) — turning it right into a router or community equipment with two gigabit Ethernet ports.

“[The] CM4 Router Board is an enlargement board based mostly on the Raspberry Pi Compute Module 4,” the corporate explains of its newest launch. “It brings Raspberry Pi CM4 two full-speed gigabit community ports and affords higher efficiency, decrease CPU utilization, and better stability for a very long time work[ing] in contrast with a USB community card.”

Designed for each the Raspberry Pi CM4 and the CM4 Lite, the latter missing on-board eMMC storage and as a substitute utilizing a microSD slot on the provider board itself, the CM4 Router Board consists of two full-speed gigabit Ethernet ports with the choice of Energy over Ethernet (PoE) assist through the Raspberry Pi PoE Hat or PoE+ HAT. One port connects to the CM4’s on-board Ethernet, with the opposite tying a Realtek RTL8111E controller into the system-on-module’s PCI Specific lane.

Elsewhere on the board is a full-size HDMI output, a single USB 2.0 port selectable as USB Host or Deviec, a USB Kind-C energy enter, and a 40-pin general-purpose enter/output (GPIO) header. 52Pi has additionally included a compact 0.91″ OLED show, linked to the Raspberry Pi CM4 over I2C, and a 5V fan header with pulse-width modulation (PWM) management – although no fan is bundled.

The board is technically supported by any working system suitable with the Raspberry Pi household of single-board computer systems, however 52Pi is concentrating on using OpenWRT as a router, gateway, firewall, or different community equipment requiring two Ethernet ports. For many who want greater than two, the corporate recommends pairing the board with an exterior gigabit Ethernet change.

The 52Pi CM4 Router Board is listed on Seeed Studio at $54.90 earlier than quantity reductions, supply-your-own Raspberry Pi CM4; on the time of writing, nevertheless, the merchandise was proven as out of inventory.
