In the last couple of days I've soldered up the first prototype of the ServoTimer II.

Here it is next to V1.6 of the flight computer
I finally, got it running and bench tested tonight. I'll make up a couple more in the upcoming days and then fit them in deployment mechanisms and test fly them quite a few times. If all goes well, then I'll get actual boards made by a PCB manufacturer.
All up it weighs ~6 grams with the battery clip adding another 2 grams.
