RadioMesh v1 - new universal platform of LoRa network [in progress]

This project in progress! It have some issues but you can play with it and change it too.

This case created especially to build new universal platform of LoRa (Long Range).

About LoRa from Meshtasic.org
Meshtastic® is a project that enables you to use inexpensive LoRa radios as a long range off-grid communication platform in areas without existing or reliable communications infrastructure. This project is 100% community driven and open source!
The radios automatically rebroadcast messages they receive in order to create a mesh network so that everyone in the group can receive messages - even from the furthest member. Depending on settings used, the Meshtastic mesh can sustain up to 80 device nodes.

Meshtastic radios can be paired to a single phone so that your friends and family are able to address a message to your specific radio. Each device supports a connection from a single user at a time.

When you send a message on your Meshtastic companion app, it is relayed to the radio using Bluetooth. That message is then broadcasted by the radio. If it hasn't received a confirmation from any other device after a certain timeout, it will retransmit the message up to three times.

When a receiving radio captures a packet, it checks to see if it has heard that message before. If it has it ignores the message. If it hasn't heard the message, it will rebroadcast it.

For each message a radio rebroadcasts, it marks the "hop limit" down by one. When a radio receives a packet with a hop limit of zero, it will not rebroadcast the message.

Features of this case
- the designs provide for the placement of a speaker and microphone (a number of people made ability to transmit voice messages via LoRa);
- place for two quick change batteries type 18650 (parallel connection);
- place for Type C data and charging connector;
- window for 0.97 OLED display that uses in most cases in such projects;
- one button in the center of device for functional regulation;
- hole for antenna;
- place for dock station I/O connection;
- a loop space has been added on the top of the case for easy carrying.

Abour dock station and I/O port
In my opinion, we need to use dock station to add more functionality to mesh devices.
Most of the all such devices that we can buy on Amazon of Aliexpress looks like board with main components and additional pins around. So we can print some case for it and use as is and forgot about this ports or it will be home device with wires around. So my idea to use this device outside as LoRa communication and same time after installing to dock station it wil add: LoRaWAN, temperature and pressure, relays, charging, external antenna and so on.

How to build it?
At first I need to say that board for this case is NOT created yet. Maybe you can try to build it. In the future I will try to build dock station.

Generally you can find a lot of manual in the internet. In most cased it is ESP32 + E22-900M30S + GPS + OLED 0.97 inch display combination.
