I've been testing my Locosys LS20031+ ArduPilot V1 at 38,400 baud. I noticed in Realterm several days ago that the actual data stream of characters is only 1140 characters/ sec, (see following screen cap) which would be ~12,000 baud. I'm…"
I'd have to guess that your GPS is getting a very weak signal. Are you using the gear indoors far from a window, on a bottom floor in a multistory building or when it is raining? Try moving the ArduPilot near a window.
"Chris & tychoc: Thanks for the tips, it is now working. I used my multimeter to learn that the LED wasn't connected to ground, so reworked the solder at the cathode side. More practice with SM! That is one tiny blue LED, the smallest that I have…"
"Chris: I made one of these daughter boards to learn how to do surface soldering. It is working fine powering my LS20031 at 3.3V, but the power LED doesn't light. The LED is speced at 10k. Is it possible this should instead be a 1K LED, like those in…"
As soon as I read your posting and read the specs I decided to buy some, which arrived in the mail today, nice service! Thanks for the tip about soldering this 3.3V Dc/Dc board. I see what you mean. I am amazed that this tiny board can…"
Nice looking DC/Dc board at a good price! I found the datasheet here, which shows the Vin, Vout etc on p.21 http://www.part-datasheets.com/data/austin.pdf
I see that you solder onto the bottom of the board at the "LISMC" pads- those 4 groups…"
An old friend developed a nice Rogallo winged RC plane which he calls the Hawkeye. If interested, you can read about it at his site- http://electricflights.com/hawkeyemainpage.htmlI test flew the Hawkeye last summer into the fall, until the rains…
