2. Replaced the SR602 PIR sensor with the AM312 PIR sensor.
The SR602 was, in my experience, prone to constant false misfirings even in completely empty rooms. In addition its orientation requirements
are awkward (pins on the left or right side). While it's possible I just had a bad batch, this soured me significantly to these sensors,
especially after reading many other similar reports around the internet.
The SR602 was, in my experience, prone to constant false misfirings and hard to enclose due to its shape. In addition its orientation is
awkward (pins on the left or right side) which made building around it difficult. Thus, this sensor has been replaced with the nicer,
more straight AM312 PIR design. This does add vertical height to the sensor but I consider this a good tradeoff, and think it looks neat.
Thus, this sensor has been replaced with the more reliable AM312. While the form factor fo the AM312 leaves a bit to be desired (sticking
up by about 1cm more from the board), and in the end this sensor misfires just as much as the SR602, I've committed to the change.
Note that like all cheap PIRs, the AM312 is prone to misfiring if exposed. For this reason, [the case](/case) is recommended for any serious
PIR use-cases.
3. Completely redesigned the custom PCB around the above sensor changes, which is now more compact in a 50x55mm almost-square configuration.

### To Solder or Not To Solder
Personally, for my Supersensor 1.x's and the initial batch of Supersensor 2.x's, I directly soldered
all the non-ESP components to the board. This proved to be a major mistake when I later decided
to switch from SGP30's to SGP41's after some testing and I had to desolder all of them, ruining
several PCBs in the process. It was also a hassle to desolder the existing sensors for reuse
during the 1.x to 2.x conversion.
I strongly encourage anyone building one of these units to leverage sockets for all components. First,
this provides good spacing between components which can help with general better performance. It can
also allow for quick swapping if any turn out to be defective or if future changes are warranted.
As a result, I actually strongly encourage anyone building one of these units to leverage sockets

**If you use the [case](/case), it is sized assuming socketed components!** So for case users you
must socket all components.

Note that due to the PCB design, you *must socket at least one* set of components - either the ESP32
or the sensors on the front. Due to the positioning and overlap, it would be impossible to solder
everything directly to the board, as the ESP covers several of the solder points of the front
sensors and vice versa.
