Not sure what's going on with this forum, but there seems to be very little activity in getting answers. Since there was never any reply to this related post: http://forum.anarduino.com/posts/list/101.page, I'm posting a new thread.

I have two each of the -HW-915 and the -CW-915. I am using modified version of the TNode sketch that gates power to a sensor using Anarduino pin D6. The sketch worked great with the -HW-915, but then I bought the -CW-915 and I get a high current draw (~50mA) when I set pin D6 low. I questioned the schematic, so I ohmed out the board and traced pin D6 back to pin 6 (DIO2) of the RFM69CW. However, the schematic shows pin D6 as unused. I also ohmed the -HW-915 and verified D6 is not connected to any of the RFM69HW pins.

So it seems there is a mismatch between the actual -CW-915 and the schematic shown on the website. Unfortunately I already had boards fabbed based on the schematic for the -HW-915. It would be really nice if I could get a true schematic for the miniWirelessCW...

Greetings,

It sounds to me like you have received a special version of the miniwireless which is geared for use with DIO2 connected to D6.
As for schematic, it is the same--except for connection of the radio DIO2 to MCU GPIO D2. Obviously there could be potential issue on D6, depending on your configuration and usage.

We had several customers requiring quantities of this version, and so we had built up 2000 units.
Not sure how you managed to get this one over the normal -CW, as we don't offer DIO2 version--except by request.

We are happy to replace them for you for free.

Here is the schematic for the MiniWireless-CW

Rick, sorry I didn't see this post before replying to this thread: http://forum.anarduino.com/posts/list/101.page. I must have glossed right over it.

I would like to have replacements if possible, since DIO2 being connected to D6 is interfering with my adapter board when my code tries to drive D6. I basically get a short and the whole thing resets. Took me a while to figure out what was happening. Thanks.

No worries, I also replied there as well.
I have not heard back from you, but go ahead and send us back the D6/DIO type for free replacements.

students who fail to comprehend the numerous areas of the subject finance can seek complete finance assignment help from the experts of MyAssignmenthelp.com. If you are one among those, ask finance assignment assistance from us and know the subject details from our Ph.D. experts.  This is the point where they seek project management assignment help???????. But again there are confused where to go because there are so many service providers. So, here are a few general queries of the students answered by MyAssignmenthelp.com.
