- 2 internal serial port
- 4 ports USB hub with 3 internal, 1 external USB ports
- IDE port for the 1.8" hard drive with ZIF Flat cable
- 2 socket for external usermade board
- some points for soldering wires directly to board (from external board to 10349 for example), easy hardware developing.
internal USB2, USB3, USB4 1 - power 2 - D- 3 - D+ 4 - GND
J7 is the serial port 1 - RX 2 - TX 3 - CTS 4 - RTS 5 - GND 6 - removed, used as key
J7 pin layout (1 is marked) (GND) (RX) 5 3 1 6 4 2 (TX)
J4 for connect external boards. All wires of J4 connected to the solder pads. For make connection via wires.

A serial console can be connected to the first com port available on 10349 board.
The port settings are 115200 bauds 8N1 parity.
You can use minicom, cu or ttylog on computer side.
It has DC-DC converter 3.3V->5V 1.5A. Each USB port has current limit to 300mA. Each port is overcurrent protected via USB power distributed systems. Use both IDE hard drive with USB devices can be overload Power over Ethernet equipment. Use external additional power injector.
Power consumption in different configurations
Here are some results on power consumption test made in different configurations with Elphel 353 camera, 5MPix sensor, 10349 board, 1,8" HD and USB staff...
|2400 milliwatts||just booted|
|3000 milliwatts||after setting image parameters|
|3700 milliwatts||streamer on|
|3300 milliwatts||streamer off|
|3800 milliwatts||streamer on and somebody playing the stream|
|5000 milliwatts||with streamer on and HD writing at full speed (dd)|
|5800 milliwatts||streamer on, HD and USB-flash writing at full speed|
|3300 milliwatts||back to streamer off|
Tests was performed with Linksys SRW224P POE switch
Kit for Developers
- for serial cable - connector A3B-6D-2C (Digi-Key) - 1 + half of AE9873-ND (Digi-Key) - 1
- for internal USB sockets - AE10179-ND (Digi-Key) - 1
- for additional boards connectors 3M5311-ND (thru-hole 2mm, Digi-Key) - 2
- or for additional boards connectors 3M5309CT-ND (SMD, Digi-Key) - 2
- blank PCB board V1255-ND (Digi-Key) - 1
In new revision of this board we want use much more IDE interfaces.
* IDE port for a 2.5" hard drive * IDE port for CompactFlash card * IDE port a 1.8" hard drive with ZIF Flat cable * SATA port
For make SATA port we can use IDE<->SATA bridge or soft IP core in a FPGA.

Now I can`t found any datasheets for this. These are big secrets of the companies :(
I've got several different IDE-SATA adapters that we're going to test with ETRAX IDE port. They all have one of the following 3 chips:
- Silicon Image SiL3611CT80 - seems to be discontinued by the manufacturer?
- Marvell 88SA8040-TBC
- Sunplus SPIF223A-HF022

maybe (if you haven't already implemented) it will be usefull putting a small led that indicate the recording status
- standby =led light on
- writing =led light pulsing
Body of camera for developers
Case A consist of a large window on the top and transparent clear plastic panel for closing. Anybody can easy modified this panel for any application.
Case B consists of a large space with two bodies. Can use same as back panel can use for backpanel clear plastic too.
