[FEATURE] Design PCB for ESPRI

Is your feature request related to a problem? Please describe.

In order to use this project there is a PCB needed.

Describe the solution you'd like

Likely the PCB should be:

• Lolin Lite addon board hat - this way it contains minimal amount of components, and can use commercially available board host that works and its cheap
• Uses Kenwood connectors the same way AIOC does (soldered audio jacks)
• 3.3V input pin that can be connected or disconnected (to allow experimentation as powering options are undefined atm)
• Kicad design with Gerbers that can be sent to JLCPCB so everyone can build it themselves
• SMD components should be of 0805 size for easy soldering
• SMD MOSFET transistor 2N2002
• Optional slot for LDO to power the ESP from 8.4V (usual voltage of double cell lipo used in handheld radios)
  • Perhaps only conversion from 8.4V to 5V is needed, as the board has 5V -> 3.3V LDO already
  • AMS1117 / LM1117-5.0 0 ≤ IOUT ≤ 800 mA, 6.5 V ≤ VIN ≤ 12 V (widely available, draws a lot of current so not great for battery operation)
• Optional led, gpio, buttons in case needed further down the road

There is no 5V pin on lolin lite boards, so 8.4V conversion to 3.3V is needed. Use HT7333 LDO.
