New Micro MinimOSD

Pr][nCe · April 23, 2015, 11:24:59 AM

Mine got delivered yesterday running MW OSD R1.3 firmware, and in the Emax 250 Pro in no time with Naze32, lovely little well tiny board, just got to sort out what i want to see in me gogs now.

Looking good, be very careful with those pins soldered straight to the PCB for the video in/out, mine ripped off the board with the tiniest of knocks, I would suggest either soldering direct and relieving strain somehow or use a load of hot glue to secure the pins too!

Thanks for the tip. will get some hot glue on it.
Was going to solder direct, but then thought get it up and running first make sure alls ok, find a tidy placement and then shorten leads and solder.

Got my 2 boards today , had a problem connecting the FTDI and getting it working .
Only when i plugged it directly to the board did I clear the eeprom and load up MWOSD 1.4 .
So my next step is to try it with the afromini 32 in plane mode .

Any other tips and ideas will be helpful.

I believe home is set upon arming the naze, so just make sure you have a decent lock before arming.

In normal operation, all altitude / distance/ direction / GPS position etc is as sent from the flight controller to the OSD. All it does is take the info and displays it. Quite dumb in some ways.
The home button on the larger minimosd board just resets it ! You don't lose any functionality.

For awareness, you can also connect a GPS chip to it as well and use it as a very cheap normal OSD without the naze or other controller. More for the plane guys...

Oh that last bit is interesting, so just osd and gas, no need for an apm etc?

@brucey - yes the later version will run pretty nicely with just a gps chip connected. Get almost all of the functionality except the horizon indicator. Even looks the same on the display.
Can still be configured from the GUI
But not the Menu - although that said, this will be available via the tx sticks soon!

Can also be run standalone without gps of course - even for a groundstation for rssi and voltage :)

Vid from some testing...

! No longer available

Cool, can you post some details up of what to buy and how to hook it up. .. lazy I know ;D

I got mine from here http://www.ebay.co.uk/itm/MICRO-MiniOSD-Mini-OSD-for-APM-Flight-Controller-MWC-KV-Team-Mod-/252031366202?

took about 10 days and works a treat - using mine with minimosd-extra for a new mini pro apm

Brucey · July 25, 2015, 08:58:35 AM

Ok thanks, and a compatible gps for the osd?

Brucey · July 29, 2015, 07:50:43 AM

Just ordered a couple of these to try stand alone with a gps

Excellent, that means your Skyfun will get a satellite lock in less than an hour!

Step 1 Load mwosd onto the minim.

In config.h, select one of the following:
//#define GPSOSD_UBLOX // Uncomment this if you are using a UBLOX GPS module for a GPS based OSD
//#define GPSOSD_NMEA // Uncomment this if you are using a NMEA compatible GPS module for a GPS based OSD
//#define GPSOSD_MTK // Uncomment this if you are using a MTK module for a GPS based OSD

Set up your volts, amps etc etc.

If not using RSSI and have a spare rx channel, can also use this...
//#define OSD_SWITCH_RSSI // Enables 3 way screen switch using a TX channel via a RX channel connected to the OSD RSSI pin. Typically used for GPSOSD.

Step 2 connect up to gps – rx/tx/gnd/5v to the programming port.

Auto sets home once it gets 5 sats
It says disarmed until >20m from launch point then it arms, starts flight timer etc.

When it lands it displays summary screen for x seconds. I think needs to be within 50m of launch and zero groundspeed or something

Still consider in development, but there are a number of guys out there using it.

Any issues let me know. Always looking to improve it.

Just to add, i have done a lot of testing with GPS chips. Most of cheap ebay ones are crap...

This one is the mutts nuts. Nothing else touches it...
I regularly get 20 sats in the air. Why so good - it uses combination of Russian and US sats.

Worth the money. If you get one, make sure it says mini 8 on the module - an cirocomm on the antenna. Not all ebayers send the module in the picture. Annoying
