new < 1g dsm2 compatible rx's!!!

It appears that two of the holes are + and - power and the other four are where the signal lead from the servo would go.

So lots of cutting, wire stripping and soldering

That is exactly right.

[daliad100]

I'd personally solder a short length of wire into the +ve and -ve holes and then attach all of the servo power and battery connections to that to make it a bit easier to do.

Even though it would require a new transmitter I still really want one.

That looks like a nice bit of kit, but considering I was 35g underweight on the weekend, I'll stick to the oh so heavy 2.2g orangeRX That plus my soldering skills aren't up to much.

I got my rx this morning, its smaller than it looks in Jims pictures. I bought myself a usb microscope as it wasn't much more than a maginifying glass It looks like the through holes for the pads are 0.1mm diameter so I may have to rethink how I am going to solder this.

[peterwaller]

Yes I got mine also and they are tiny but the pads are bigger than that.
I have some 0.22 mm wire and that goes through the holes easily.

it's ridonculously small!

[Andrew_Hibberd]

Got the old soldering iron out this evening and fitted it to a baby-o:



And with the RX soldered on



I struggled with this, not something for someone who is not confident with a soldering iron.

[Jonny]

i take my hat off to you sir how much does the completed unit weigh?

[earthwormjim]

Nicely done.
Do baby O's work as dual motor control "out of the box"?
Or do they need programming up,Andrew?

[Andrew_Hibberd]

The weight is about 2g for dual motor speed control and RX. My scales are only 1g accurate so I can't get much better than that unfortunately. The baby-o doesn't come rc controller out of the bag, however pololu do have an example rc code for the 3pi robot with mixing that works but for different pins I have the nano rx fitted to. The code is a bit hungry so if more complex things are required it needs a lot of reprogramming.
