Qotom Q1900G4-M is a motherboard designed for networking applications thanks to four Gigabit Ethernet ports connected to an Intel Celeron J1900 quad core “Bay Trail” processor. The board supports up to 8GB DDR3 RAM via a SO-DIMM slot, storage through a SATA port and an mSATA connector, and WiFi or cellular connectivity through a mini PCIe slot and SIM card slot.
Qotom Q1900G4-M board specifications:
- SoC – Intel Celeron J1900 quad core “Bay Trail” processor @ 2.0 GHz / 2.41 GHz (Burst) with Intel HD graphics (10W TDP)
- System Memory – 1x SO-DIMM sockets for up to 8GB DDR3 memory
- Storage – 1x SATA 3.0 port + power (14 & 15), 1x mini PCIe connector for mSATA SSD (16)
- Video Output – VGA (5)
- Connectivity
- 4x Gigabit Ethernet ports (3) with Wake-on-LAN support
- SIM card socket (17)
- USB only mini PCIe connector for WiFi, 3G or 4G (18)
- USB – 3x USB 2.0 host ports, 1x USB 3.0 port (4)
- Expansion
- Front panel audio header (6)
- RS232 header (10)
- USB header (12)
- Misc – HDD LEDs (2); power LED (7); power button (8); CPU fan header (9); automatic boot jumper (11)
- Power Supply – 12V DC (1)
- Dimensions – 120mm x 120mm (Nano-ITX form factor)
- Temperature Range – -10°C to 50°C
The board comes with a heatsink by default. You’ll find some details about the hardware in the user manual. The board is said to run Windows 7/8/10 and Linux distributions, especially now that Linux 4.11 is almost out with several fixes for Bay Trail processors.
Since the board is supposed to comply with Nano-ITX form factor, you should be able to find a case for it, but if not, Qotom also sells Q190G4 mini PC based on the board. It reminds me of X29 mini PC, except it comes with four Gigabit Ethernet ports instead of just two, and lacks HDMI and audio ports, as it targets networking applications.
Qotom Q1900G4-M board sells for $99.90 + shipping, while Q190G4 barebone mini PC goes for $120 plus shipping with a 12V/3A power supply and free VESA brackets, and you can optionally add WiFi, memory (up to 8GB RAM), and/or storage (up to 64GB SSD) to your order. I could also find Q1900G2-M motherboard still with 4 Gigabit Ethernet port – contrary to what the name implies – and selling for $91 + shipping. I have not been able to find a difference between Q1900G2-M and G1900G4-M. If you do, let me know.
