APM Oilpan Rev. H, Version 1.0 now in production!


The new ArduPilotMega Shield "Hotel' Version 1.0 has finally replaced our old and problematic Foxtrap 2.2, many of the changes are just to accelerate the assembly process and reduce production failure rates, working in conjunction with the very supportive Invensense Team (Thanks guys!).

Note: if you are a user with the current boards, they're fine. The problems were in the production process, which required us to go through extra steps to ensure they passed QA. The new board is more for our sake than yours!

Manufacture changes:
-Improved gyro pads.
-The boards now came with Lead-Free Silver Immersion for an even surface (Turns goldy when baked).
-Added one 0603 resistor pad on voltage divider for automatic machine placement. I should have added it to all the resistors. =/

User Experience:
-Now that is easy to assemble, boards availability will be improved.
-Solder jumpers to optionally enable/disable gyro low pass filters.
-Added labels that suggest where the female headers should be placed.

Bugs fixed:
-Reset button now works under any condition.
-Analog supply for the pressure sensor is now attached to the analog 3.3 voltage regulator.

By the time I wrote this post I still had some Oilpan in stock, please hurry because we are moving to a new warehouse and we may be out for around one week again, just in time to start production with our new Japanese made Manncorp 7722V. Many thanks to the Mancorp team that is also located next to us in San Diego,CA!

I can vouch for this... atmel has been behind when it comes to availability for a long time now. Economic downturn and the such and they are trying to avoid the boom-bust nature of the economy. Works for them, sucks for us.

I use the data flash chips in a product and you couldn't find them anywhere for a few weeks a while back.

Chris talked about it before with an article link that explains the situation:

OK, so about the filters again. I understand the added flexibility for the 3-D accel, thats great!.Ive also noticed jumper pads for the xy gyro. I assume this is to add the same flexibility..?

Is to enable/disable the low pass filters...

The switch below the voltage dividers came of when I unplugged the usb cable. I think solders are not strong enough. Maybe it can be glued to the board before soldering.

Just got one of these boards and there is a sticker on it saying that the Data Flash resistor has not been soldered to the board and there are some resistors enclosed. Where does this resistor go?

MB1280, Sorry I can understand your question, is your board brand new? Or you send it back for repairs?
Comment by MB1380 on October 13, 2010 at 12:03pm
Yes its brand new. The sticker says " Data Flash Resistor not soldered on board" on the back and there were 4 normal (not smd) resistors enclosed in the box also....

Can you please send me a top picture of the PCB? The resistors (3.9K) are optional resistor for the voltage divider to monitor LIPO cells, is something else.
