Hello Tilman, this is really a very nice design. I have ordered a pack of PCBs from elecrow, based on your gerber files, and have a few questions:

• in your BOM you have listed 5 smd-capacitors and 7 smd resistors, but on the PCB i have solderpads for 6 capacitors and 8 resistors. Can you just explain?
• is there a uniflächentaster-model for 2 ways?
• i think i have to flash the bootloader first, do you have a tutorial for this, and a sample-sketch for the board?

Thank you very much

Thank you so much, that's it.

Re: Slim Node scene controller/ keypad

Hello, everyone,

I have a little problem with this. I'm trying to compile the sketch of @AWI that was used in this older article. But unfortunately it fails due to the following error message:

error: call of overloaded 'sleep(const int&, int)' is ambiguous

   DVint = sleep(DV_int, FALLING);           // sleep, node wakes up on key interrupt, (sleep returns int number)

Can someone please give me a hint as to what might be wrong?
Thank you very much
