Hi,
I'm working through building the controller (pcb 10 version 3. 7/2013) and I'm after a bit of advice on resistor network component RN41 this is made up of two, six pin packages but I don't know which way the 'dot' should be indicating the start of the network, or does it not really matter.
Thanks in advance

Those are the isolated type and are symmetric. The other "star", bussed types are important to get the common pin correct (at the square) but these two don't matter. Why there are two "RN41's" is anyone's guess.

Thanks Greg that's answered my question, so I can crack on.
Thanks again

One for Ch A and One for CH B? Isolation? :?:

Possibly, but I would think that crosstalk within the resistor network would be low enough with the resistor-to-resistor "isolation".

All done, made a schoolboy error not bending the caps down under the discovery board, new ones fitted now and online, station ID 723, stand by for more questions :grin:
