The iSpindel is a free-floating intelligent hydrometer and thermometer with Wifi support for continuous real-time monitoring. The forum of  Beer brewer (http://hobbybrauer.de/forum/) has developed a WLAN spindle.

This set consists of all components
A etched circuit board is delivered.
The board is in a very good quality.

The new board has SMD components, because several customers have complained that the resistors can easily be confused.

All advantages of the board version:
  • The temperature switch has been moved.
    • no more collision with the charge controller
  • Charge controller has been moved.
    • No more collision with the socket for the battery.
  • The 390 Ohm resistor was replaced by the BAT-43 diode.
    • more stable deepsleep
  • SMD components were placed directly
    • no more color codes to analyze.
