Bill of materials to various combinations of Edgemap related kits.
Edgemap with RPi 2W Zero
With this kit you are able to host World Map + World Terrain + limited amount of imagery on single MicroSD card. Edgemap running on Raspberry Pi 2W Zero creates hotspot and you can connect your mobile or laptop to it and use Edgemap user interface and exchange messages over Meshtastic (LORA) channel. Perfect light kit for initial testing but creates Wifi hotspot and is not suitable for RF hostile environments.

Edgemap with RPi 4
With this kit you are able to host World Map + World Terrain + limited amount of imagery on single MicroSD card. Edgemap running on Raspberry Pi 4 creates hotspot and you can connect your mobile or laptop to it and use Edgemap user interface and exchange messages over Meshtastic (LORA) channel. You can also use RPi 4 kit with wired Ethernet and disable Wifi completely. In which case RPi 4 is either DHCP client on your LAN or acts like DHCP server in you LAN - depending your use case. Perfect and more robust 'appliance kit' when you require wired Ethernet on RF denied environments.

Meshtastic Radios
You can check official Meshtastic site for list of available radios. There is good amount of details and frequency area (US/EU) is one main difference on these models. I have experience of LilyGo and just recently Heltec V3 radios. I have created 3D printed case for my LilyGo boards and it mounts nicely on your laptop lid.
Software images and Maps
You can download my Open Source Edgemap from Github and burn it to MicroSD card. Please note that doing MicroSD card image + maps installation requires Linux computer since card uses EXT4 filesystems. You need to download full planet pmtiles from this page and optionally you can download full world Terrain from this link. Both of these files need to be copied to second partition on MicroSD after you burned initial image from github.
Note that copying these 100 GB's files to MicroSD requires patience but once it's done, they are fast to use.
