-  There is an experimental ESP32 target but since platformio only supports SDK 1.0.6 and the WIFI connection is really slow compared to ESP8266, 
-  so the recommendation is to wait for support on 2.0.x branch. With the tested version an wifi connection takes 3-8s on a ESP32 compared 
-  to 0.5s on an ESP8266. There is also a bug in OneWire connected to ESP32 that has not been fixed in the main repository yet.

   The debug target can be unstable and crash the device under certain circumstanses. Excessive logging to the serial port can cause corruption and crashes.

-There are lots of resouces out there on how to build the hardware for an iSpindle so I will not go into details on that part. Here are two of my builds using the iSpindle PCB v4.

+There are lots of resouces out there on how to build the hardware for an iSpindle so I will not go into details on that part. I typically use one of the 
+excellent pcb boards that, for example the iSpindel PCB v4.0 from Cherry Philip. Here is one of my standard builds using an esp8266.

-It's possible to use this PCB and mount an ESP32 on top of that. It must be an pin compatible ESP32 and the one I used was called *ESP32 d1 mini*. Since this is the same width as the PCB you need to 
-mount it really close to the PCB in order for it to fit in the PET tube/container. I also had to smooth the edge of the ESP32 in order for it to fit. 
-
-I would suggest that you try how it fits into the PET tube before soldering it to the PCB. Make sure that the battery is attached since this will be a really tight fit.
-
-You also need to desolder (remove) the RED ON LED from the ESP32 or the battery power will be reduced a lot.
-
-Final thing is to add a resistor between A0 (Analog PIN) and ground of 470k. The reason is that the esp8266 has a build in resistor which 
-the esp32 does not have. So in order to get a valid voltage (less than 3.2V) on the A0 pin this is needed. Once the modification is done you might
-need to adjust the voltage factor so the battery reading is correct.

+
+* esp32 mini, this was the first board i tried which is a smaller form factor of the first generetion esp32 with 2 cores. Slow on connecting to wifi is the main downside. 
+* esp32c3 mini, a newer version based on the latest risc v7 architecture, is seen as the replacement for the esp8266 with bluetooth support. 
+* esp32s2 mini, similar to the c3 board but without bluetooth support. 
+
+It's possible to use this PCB and mount an ESP32 mini on top of that (c3 and s2 are prefeered). The esp32 mini is a larger formfactor and can be hard to fit into the tube.

+Adding a reed (magnetic) reset switch
+=====================================
 
 A reed switch is a switch that reacts to magnetic fields. The ones I have tested are normally open and close in proximity to 
 a magnet.
