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.

• Single-Button can be realised by bringing signal to mosfet along with diodes
• Simple STM32F042 can be used
