Just got my hands on the production version of the ACTion P92 distribution board - OK so I had the prototype on Gry Maritha, but here is noe of the shipping versions. If you are a bit wary of building something like an ESC, this is a good project to learn about building PCBs and to get a bit of confidence before trying something a little more complex. Also a cracking way of tidying up the wiring.
Stage 0ne is to arrange the components make sure you know where everything goes. The P92 is different to other Action boards in that it has the component legends printed on the board. This makes it easier to assemble.
First stage is to insert R1, R2, C1, C2, D1 and D2. I like to place the parts in byheight order - this way you can flip the board over to solder the leads and the weight of the board holds the components in place. So put in the resistors and solder, then the capacitors then the diodes (LEDs). Remember when inserting the diodes, they go flat to the board. Also they are polarised, make sure you align the flat on the package with the little line on the outline on the PCB. Once they are are all soldered in place, crop the leads just at the top of the solder bead.
