h1. Eval
* Pressing On-button must switch 240V line
** Battery driven?
*** Will there be an plumbum battery or only regular powersupply
** A simple 1,5V Alkali will do.
** -Button can handle 240V-
** An 18650 is perfect. Along with the MCP73871 or only MAX1811ESA+. No integrated LDO necessary, only SSR is switched. AUR9811DGD only 33 Cents.
** An 18650 is way too big. We only flash the LED for a short time. Ne Knopfzelle wuerde es tun.
* Single-Button can be realised by bringing signal to mosfet along with diodes
* Simple STM32F042 can be used
* Mini-USB connector for direct charge.
* 5V AC/DC Wandler integrieren; 5W, >80% efficienty; Keine Schnelladestation, nur effiziente powerline. efficienty
* Strom messen; STM32-32K-Variante sinnvoll; sinnvoller wie Akku messen der eh bestromt wird wenn geraet eingeschalten ist.
** Liegt altes Design noch wo rum?
* USB A Buchsen; 1 2 Stueck on Board, Terminal fuer weitere 4 via Kabel
* Timeout
** Buzzer fuer intervention, startup, shutdown. Hab ja noch genug rumflitzen.
