Strengths and weaknesses

Arduino UNO Q 4GB (ABX00173)

  • + Linux and a real-time MCU on one board
  • + UNO-compatible headers plus Qwiic connector
  • + Low power draw reported, about 0.5 W idle
  • − No Ethernet port listed
  • − No SD or M.2 slot listed
  • − One reviewer found it slower than a Raspberry Pi 5

Skip it if:

  • Buyers who need wired Ethernet, since none is listed.
  • Anyone who wants SD or M.2 storage expansion.
  • Users who want the fastest general-purpose Linux board at this price.

Raspberry Pi 3 Model B

  • + 40-pin GPIO header plus CSI camera and DSI display ports
  • + Built-in wireless LAN and Bluetooth
  • + Production promised until at least January 2028
  • − Ethernet is 10/100 only, not gigabit
  • − No USB 3; four USB 2.0 ports
  • − microSD only, with no M.2 or NVMe support published

Skip it if:

  • Anyone who needs gigabit Ethernet or USB 3 for fast file transfers
  • Buyers who want NVMe or M.2 storage rather than a microSD card
  • People who need more than 1GB of RAM for several services or VMs
