This is a list of tested hardware for the BBBMINI. If you have other hardware in use, please let me know, so I can update the list.
I can confirm it works fine with an EBAY M8n 3.3v with HMC5883L.
I have no GPS lock with 3DR GPS LEA6 V1.1, 5.0V nor 3.3V VCC, (-B /dev/ttyO5).
Is there any experience on this GPS ?
I was able to get the 3DR V1.1 LEA-6 GPS/Compass module to work, but it required the use of a Sparkfun level shifter to mate the 5 vdc I/O of the GPS to the BBBMINI GPS 3.3v I/O.
Does Mission Planner tell you "GPS no fix"? On my BB my serial port was /dev/ttyS5 not tty05. You might check it.
Thank you for the inputs. I will dig 3DR-GPS more:-)
It is confirmed that "-B /dev/ttyS5" works with 3DR GPS LEA6H Ver1.1 (3.3V).
Managed to get an ESP8266-07(with external antenna) working on my BBBmini. Just bench tested it for over an hour connected to Mission Planner - and it still works. I used the info at https://pixhawk.org/peripherals/8266 & https://github.com/dogmaphobic/mavesp8266. To get it into boot mode I had EN - high, GPIO-0 low, GPIO-2 high, GPIO-15 low. For normal use - EN - high, GPIO-0 disconnected, GPIO-2 high, GPIO-15 low. 3.3v used. 921,600 baud rate.
Nice job. I understand why a Pixracer user might want this but is there an advantage for BBB users vs a standard wifi mini dongle?
I don't know Mike. I just wanted to see if I could get it to work with the BBBmini and decided to share the information.
In addition to the above I'm going to add 10k resistors to the EN & GPIO-2 connections.
Great i have a pair of these dongles in the mail, keep this stuff coming!
They are just too cheap to resist :)
ESP8266 + Arduino NANO + FTDI232 = Dont leave home without it :-)
Here's a picture of my 1.4 mod to get the Battery Voltage & Current readings.
The output of the 3DR-clone power module goes to 2 x 10k pots. output of arm goes to AIN0 (P9-pin39) for voltage and AIN1 (P9-pin 40) for current. I soldered a standard RC connector and fixed it on the board with a small gage wire wrapped around connector + crazy glued.
Set the config parameter as:
