## The Moonshot
Intrigued by the size of the little bugger, I decided that I would try my hand at miniaturization. The goal was to create the smallest ESPSomfy RTS device that I could without the benefit of a 3d printer or designing a PCB for it. After all I have a bunch of breadboards laying around. The goal was to make something as tiny as I could. Just in case I decided to build a rocket to the moon I could take it with me while still having room for a couple of bottles of Scotch.

## Parts List
Digging around in my miscellaneous parts I came up with what I needed. Below is a pic of the items I used. I created a table below to give a better description of what these items are and where I got them. What isn't shown in the pic is the 28awg silicone wire that connected it all together. I used this wire because I have 10 different colors of it. As well, silicone wire is very bendy so it can be pushed into tight spaces although any small gauge wire would do.

### Solder E07-M1101D
I used 28awg silicone wire to connect the transceiver to the breadboard. I found it easiest to solder the wire first to the transceiver then solder it to the breadboard. If you have the wire colors that I have you can use the color coding below but if you do not I would suggest making a chart of your own and record which color wire you soldered to which pin on the transceiver.

I cut one 4inch length of wire of each color (8 pieces) then carefully matched them to the pin number below. Once I got all of the wires soldered to the transceiver I used a short piece of shrink tube to keep them together. I did this so that it was less likely to stress any one wire while soldering them to the board or handling during assembly.
### Solder to Breadboard
Before mounting the ESP32s3 onto the breadboard I soldered the wires from the transceiver to the board between the sets of pins. This proved to provide a compact way of keeping the wires secure and relieve stress on the solder joints. When the ESP32s3 is finally soldered to the board, the wires will be between the two boards. The picture below highlights the locations where I soldered the wires.

#### TIP: Solder order
Start with pin the pins that are closest to the transceiver while soldering and ensure at least 5/8 of an inch between each board. Cut the wire to length while keeping the proper distance between the boards. This way when you set it into the PVC enclosure it will fit neatly with the transceiver on one side and the ESP32s3 on the other. Optimum solder order 5, 4, 7, 6, 8, 2, 3, 1.
