Hi list/community,
we would like to introduce new router supporting OpenWRT.

This board is referenced to low-cost and low-power solutions.
Sweet^2
Below are preliminary specifications:
PCB form factor: Pico-ITX (10cm x 7.2cm, fanless)
Onboard CPU: Cortina Systems CS3516 (300Mhz ARM9 Core)
300 feels slow, but arm9 is supposed to be quite efficient right?
400 MIPS according to specs. There is also dual core version of this chip.
Onboard DDR SDRAM: 128Mb 333Mhz 32bit
I would make this a SODIMM, 128 is low if I'm going to buy a board
Since our memory bus is 32-bit it is a little bit problematic with
SODIMM. There is 32-bit SODIMMs, but they are rare and expensive...
Onboard NAND FLASH: 128Mb (or more)
Related to above: Too much, go for 32Mb and solder on more ram if you
can't make it a SODIMM
Onboard LAN: 2x 10/100Mbps Ethernet
Last year I would have said "WHY NOT GIGABIT" but since I've switched to
a high quality gigabit switch plugged into my WRT I don't need more then
2 ports on the router device. (Not like we have gigabit internet yet :/)
It can be Gigabit! We considered 10/100, because of hardware price and
it is unlikely that CPU will generate such traffic... Although it is capable
of doing hardware NAT at Gigabit between Ethernet ports.
Onboard SATA: 2x SATA
This is why you don't need more then 32mb on-board. There are plenty of
CF <-> SATA adaptors you can buy for $10 off DX. (Also raid0 SDcard <->
SATA)
Onboard connectors: 2x SATA, 2x mini-PCI slots, 1x mini-PCI Express
(with USB 2.0 interface), 1x UART, 1x Pico-ITX power, 1x JTAG, GPIO ports
So the miniPCIE runs in usb mode? Or both USB and native?
Only USB. There is no PCIe controller on this CPU.
Back panel connectors: 2x RJ-45 LAN, 2x USB 2.0, 3x antenna (GSM, 3G,
Wifi, Wimax, other), 1x RS232
:O GSM
Management: Watch Dog Timer, Brown-out Reset, RTC with battery
Battery backed RTC \o/
What is the target price? depending how close to $100 this stays this
could kick some serious ass. (if it comes with a case and power supply
then I guess it can cost more, but a naked board should be close to $100
or be insanely over-powered and like $300)
We think 100$ is realistic for naked board.
Thank you very much for all comments.
