Wifi router chipsets as SOMs
- View SourceFor ultra lowcost Linux systems you can't beat personal Wifi routers
reflashed with OpenWRT. The obvious major advantage to this over the
MX233 is the addition of Wifi that includes FCC/CE.
For example the TL-WR703 from TP-Link. It has 150Mb Wifi, USB and Ethernet.
$24 Q1 shipped anywhere, about $16 FOB China
BOM for these are under $9. You can achieve the same pricing with
Realtek and Ralink. Note the $16 includes a power supply, Ethernet
cable, USB cable and packaging. TPLink makes these like jellybeans in
a factory running 24/7. Millions are sold into China as personal
routers between 3G and Wifi.
A good product that is not in the market would be to make a PCB just
like the TL-WR703 but then route the other peripherals over to an edge
connector. All of these chips have UART, SPI, I2S, I2C, etc but you
can't get to them which ruins these boards as a SOM.
The idea is that the edge connector is almost free. TP-Link could ship
the same PCB in their high volume routers. Olimex could buy big lots
and resell them into the OEM market. You also make a bunch of
peripheral boards to go with them.

no video, less capable processor than A13Different applications. Many embedded uses don't need displays. The UI is a webserver on the embedded system. They are also much cheaper than the A13. The CPU chipsets are under $3.00.--
