 <p>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 <em>ESP32 d1 mini</em>. 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.</p>
