please, what is the exact network chipset for zimaboard?

i think i found that answer, realtek

While ZimaBoard offers an attractive price point and a fanless, low-power design, it comes with one major drawback—Realtek NICs (Network Interface Cards).

ZimaBoard 1 has 1GB Realtek NICS. The original plan was to use Intel NICS but at the time ZB1 came out it was while the effects of the pandemic meant some chip’s were in short supply. Intel Nic Chips were not available and a decision was made to move to RealTek.

ZimaBpard 2 should be coming with 2.5GB/S Intel NIC’s
