Re: Das Mikro - £12 dual channel speed controller with mixing
I have started playing with my own speedos as a little side project. Is someone with these boards able to read what the h bridges on these boards are?
Thanks.
Andy

According to Joey, 4 x SH8M14 N/P dual MOSFETs...
Another thing they supply that could be useful is £7 Deltang knock offs: http://www.banggood.com/DasMikro-DSM2-5 ... 84913.html
Certainly be helpful for Nanos!

Re: Das Mikro - £12 dual channel speed controller with mixing
Hey Rory
I bought some of these RXs a couple of months ago, the 6ppm input is really nice to free up an IO pin.
Not the best chip with no logic protection on those banggood boards, still on the look out for a nice H bridge for 2 cells. I have the A4950 in my first test board. I got it nice and small 14x11x6mm with RX.

Those look good. I used the A4950s for the N2HV ESCs, but found they had a habit of cutting out if you change direction too fast, and didn't like 2S unless the battery was fully charged..
I've been thinking of redesigning my Nano ESCs to go with those RXs since they've proven themselves driving Wedge Wedge Wedge and Bad Idea, and can be made the same size as those RX.. Probably wouldn't sell them but they'd be a useful mini 2S ESC

Re: Das Mikro - £12 dual channel speed controller with mixing
Did anybody try this on 3s?
Re: Das Mikro - £12 dual channel speed controller with mixing
Just got mine running on a cardboard test bed--it's fine with a resistor between the motor terminals (although I may have added too much braking--it's pretty slow.
(Video:https://www.youtube.com/watch?v=vcwbtN9ys_A)
Here's the thing, though. I got excited and stuck a biggish servo onto the receiver. The servo immediately started jittering and twitching, so I unplugged it. But now the right motor twitches, rotating backwards intermittently.
Can adding a servo to the receiver somehow mess this up? Is there anything I can do to fix it?

Re: Das Mikro - £12 dual channel speed controller with mixing
How is the receiver powered? If it's powered via the speed controller then the addition of a servo may have overloaded the voltage regulator (aka BEC) in the speed controller.
If you've damaged the voltage regulator it may affect operation of the speed controller and will almost certainly affect the operation of the receiver. If you're lucky you can power the receiver from a separate voltage regulator (BEC) that is also suitable for powering the servo. Servos can take a significant current (over 1A) which is too much for many regulators.

Hi,
Forgive me for what is probably a stupid question but can you use any of these receivers with the das Mikro. Or can someone suggest one please. I'm a complete beginner so wiring this is going to be fun!

Re: Das Mikro - £12 dual channel speed controller with mixing
Both should be fine, you just need a receiver that accepts servo leads.

Hi thanks for replying,
Forgot to mention I've got the devo 7e tx. I know that I'd have to put some software on it to use some receivers (the two I linked in I think). Could some suggest a receiver that I wouldn't have to do the software update and would work with the das mikro as well? Also any suggestions to a good but cheap solder/soldering iron ?
Sorry for the stupid question!
