AW: AW: [Paparazzi-devel] Commercial boards

[Ethan Arnold]

Is the board Paparazzi compatible?
How big is it (dimensions?)
You mention a coprocessor, but what about a main processor?

Is the IR board comparable to the Paparazzi design? I can hardly imagine how
the board+sensors can be only 10 EUR, normally the sensors alone are at
least 25-30$!

I have a own design, with rtos, usb bootloader, usb hd.
I can sell the board, but the layout and schematic can not be
released under any gpl licence. 
A short description below.

15W 8-14V to 5V isolated step-down converter (oem)          optional
1W 5V to 3.3V isolated step-down converter   (oem)          optional
5V ldo psu 1/3A                                             optional
voltage doubler + 5V ldo for 5V yaw gyro + 5V to 12Volt flash vpp generator
(maxim/LT) for analog sensors (pressure, pyro) supply.      optional
lpc2148 cpu
serial spi flash (8Mbit) 
vcc monitoring with i2c memory (cat) 
8x 24bit adc for magnetometer, pressure sensor             optional
8x 24bit adc for 3x gyro + rel pressure sensor + 3d accell sensor.  optional
isolated rs232 tranceiver, 1Mbit max
optional 2x isolated rs232 available on request
pic coprocessor (5V) for servo output and ppm input (0.5 uS resolution)
and servo mixing.
3.3V gps

Excepts the component costs, the pcb and assembling costs 15$ / board, 
special configuration requires a minimum order of 12 boards (1 panel).

The IR board is sold separatly and costs ~10Euro including
4x IR sensors, (optional coating and housing available on request).

For a new design modification, the pcb overhead is 5$ (film costs).
Because the automatic smd placing is extracted from the eagle files,
there is no extra setup costs.

Chris
