Rectangular green PCB extension board with Ethernet port, 3.5mm audio jack, USB-C connector, pogo pins, and indicator LEDs

Khadas

Khadas Edge2 Station Extension Board development board

SKU CH-976J-MWKYV

Extension board adding 10/100M ethernet, 3.5 mm audio, UART debugging and external DAC to the Edge2 ARM PC via pogo-pin docking

  • Adds wired networking with 10/100M Ethernet port
  • Adds analogue audio output via 3.5 mm headphone jack
  • Enables serial debugging through UART with CP2104 USB-C
  • Improves audio quality using external ALC4032-CG DAC
  • Powers Edge2 board via 5 V pogo-pin connection

Expansion Board for Edge2 ARM PC

The Khadas Edge2 Station connects to the Edge2 single-board computer through pogo pads on the underside. It adds wired networking, analogue audio, and a debug console for developers who need those interfaces in a compact package.

Wired Network and Audio Under Load

The 10/100M Ethernet port provides a stable link for continuous data transfer without relying on wireless bandwidth. The ALC4032-CG DAC drives the 3.5 mm headphone jack for steady audio output during long sessions. The CP2104 UART over USB-C keeps a persistent debug channel open while the board runs.

Thermals Noise and Power Draw

The board draws 5 V through the pogo pins or the USB-C connector with no active cooling fitted. Green and red LEDs show power state while white and blue LEDs indicate UART activity. Passive operation means no fan noise and minimal extra heat inside the enclosure.

Questions about this item

How much power does the Edge2 Station draw when the Edge2 is running all day?

The Station itself has no separate power rating; it passes 5 V through the pogo pins from the Edge2's USB-C supply, so total draw depends on the Edge2 load.

What must I already own for this board to function?

You need a Khadas Edge2 ARM PC; the Station docks to its underside pogo pads and adds ethernet, audio and debug UART.

Will the 10/100M ethernet port work with my older 10BASE-T switch?

Yes, the port negotiates 10 or 100 Mbps, so it will link with legacy 10BASE-T equipment.
