Quad core 2GHz cpu, 16GB storage, wow, as you say this is just a SBC with no ethernet or HDMI port.
They are probably selling the board at a loss. Someone should make a BOM analysis.
I don't know why you'd think that.
Quad core A53, 2 GB RAM, no ethernet or HDMI? $44?
$15 Raspberry Pi Zero 2W is quad core A53, WIFI, HDMI. Less RAM.
$20 VisionFive 2 Lite has quad core A55-equiv, 2 GB RAM, ethernet, 4x USB (1 USB3), HDMI, M.2 NVMe 2242 slot. WIFI model $5 more.
$30 Orange Pi RV has similar specs to VF2 Lite w/WIFI but 2280 M.2 and the USBs are all 3.0
$30 Orange Pi RV2 also similar, but 8 core CPU with RVV 1.0 vector, 2x gig ethernet, 2x M.2 NVMe (2230 and 2280), 2 TOPS@int8
VF2 Lite and OP RV have 40 pin GPIO, RV2 has 26 pin.
ALL are comparable in Linux performance to the Uno Q, have many more computer interface and storage options.
Are they all selling at a loss?
