if this offer still stands, I’d love to take two, too!
Thanks for sharing! It works perfectly.

Hi do you still have any of these? Are they fully assembled? If so I’d be interested in purchasing one. Thanks!
Hi everyone,
I’m trying to get a fully assembled board, but it seems the rotary switch is out of stock. JLCPCB offered to source them for me at a cost of 5 x $18.73, which comes to $93.65.
Honestly, that seems a bit steep considering the in-stock price is $2 per piece.
Could anyone suggest a suitable replacement for this rotary switch in their store or recommend an alternative supplier with more reasonable pricing?
Thanks in advance for your help!
By the way, if anyone is interested in getting 2 of these boards, let me know!
I am on the way to IKEA to get a Förnuftig to build the first (non PWM version).
However, at this point I still have a minor problem understanding the logic.
The Förnuftig board uses 5V logic, but ESP8266 and ESP32 use 3.3V logic. 5V on a 3.3V pin without level shifter or voltage divider are usually not healthy.
Is my understanding correct that the ESP senses which pin is grounded via the rotary switch (top of the board/switch) and depending on that outputs a voltage to the cut legs/traces of the rotary switch on the bottom of the board/switch and then the IC on the Förnuftig board selects the highest input (whatever it is 3.3V or 5V), which is why it works without frying the ESP?
Or are the ESP pins actually exposed to 5V and I didn’t get it?
If it is all on 3.3V, why do I need a buck converter for 5V, if the logic is on 3.3V anyway and the 5V will be reduced by the ESP’s onboard voltage regulator to 3.3V (converting 1.7V into heat). Is there a reason why nobody uses a 30V(eq. 24V) to 3.3V buck converter?
Thanks! 
[edit] ^^tested it - logic is 3.3V, with a 5V or a 3.3V buck converter. Since 3.3V works, I sticked to that one to save energy [/edit]
