h1. Eval
Slider would not have adequate resolution.
Usecase is only on/off. Single Button could do the job.
Fancy ring would be nice.
90°-LEDs zeigen alle nach 'innen'.
LEDs:
* Orange, low ambient light
* Blue, bright ambient light
* Red, alarm
h2. PCB
30x30mm
logo/sensor 10x10
border 5mm; thick enough for LWL? There are some with 2mm diameter
h2. MCU
* STM32L552CCT6 way too big
* STM32F042 has a touch sensor controller according to datasheet, copilot says "no".
h2. To be verified
* Use Miniminutnik Acryl plates to check if text is readable/illuminated
** Looks very nicely
* Prepare STM32F42x eval board
** On touch area directly, another via JST
** CANBus
** Debug
