"Hi Jason,
Any idea of the charge rate? I have had a 1S 3.7 20C li-po attached and it never seems to charge up fully. If I attach it to something other than the USB3 port of the computer (say the charging port of a JBL Charge Bluetooth speaker), the…"

"Hi Martin,
Had to get a different cable as that 1S has a micro connector. The good news is the board did not blow up! But I'm not convinced its charging either. There is a good connection (as the charge light goes out when I disconnect the USB, and…"

"Thanks for taking a look. I get negative both with RTKConv and convert-skytraq-raw.exe so edited the file manually. This semi-worked (I could see stuff in the sky plot) but still didn't process anything. I then did a search for RTKlib and negative p…"

Will see what happens. Assume that the polarity on the battery itself is obvious and that the connector that comes with the board is OK?"

"Hi Jason,
I received the replacement (pre-soldered NS-RAW & adapter board) and managed to find some time to test. It logged raw data as expected (albeit the file size half the size of that logged via GNSS viewer for a period that was actually greate…"

"I just logged some data using the adapter card (new one just received), and converted to RINEX, then downloaded both the precise and broadcast ephemeris for that day. Again I cannot get it to work in RTKPost.... any chance you can take a look at my…"

I reprocessed (using your data) and got the same results (as you would expect), I then used precise ephemeris and got a slightly better result (see below plot). These links might be useful:

"Oh that's bad new! My first adapter board was DOA, so am awaiting the replacement. I am wondering what the maximum input voltage you can have on the USB (given Jason's comments about using a smartphone power bank). My goal was to create a matchbox l…"

Mark Payne replied to Martin Poller's discussion Adaptor board
"Hi Martin,
Did you use a 1s lipo in the end, and how did it work out for you? Presumably when the NS-RAW and adapter board is stacked, and there is power on USB the battery will charge, and conversely if the 1S is connected on its own it will power…"

"Hi there,
Not sure if this helps, but I processed my logged data from GNSS viewer using CSRS-PPP (http://webapp.geod.nrcan.gc.ca/geod/tools-outils/ppp.php?locale=en). I had to use RTKCONV to convert the .out file to RINEX 2.11 format (actually it mi…"
