Twin LoRa board?

I spotted this offer of getting a couple of boards made up for free:

I lack the skills or time, but it occurred to be it might be fun to get them to bolt their E5 module to the opensource Esp32:

I know this was something Disaster Radio looked at:

Might be worth starting from their Gerber? disaster-radio/hardware/board_esp32/GERBER at master · sudomesh/disaster-radio · GitHub

But adding the E5 module instead of the second ESP32.

No idea if it would actually work, but if Seed started making them it might make a nice repeater node & really help with scaling large networks.

We can make some of this board and add the support for the E5 in the software.

Yes, it might be interesting? No idea how much work would be involved though.

Prove the concept with the free boards, then do a crowdsupply?

Maybe even a three radio version? Or am I being greedy?

I have also asked the question about even adding 2.4Ghz LoRa support on another topic.

In certain scenarios it could make sense to have multiple LoRa interfaces

We could have a repeater whit a sub-GHz antenna and a 2.4GHz one to mesh the different bands

Me too, for the base schematic I think should be easy to draw (for the support component, screen, buttons). Should we think of a battery circuit?

Three radio version for what?

1, Ingress LoRa
2, Egress LoRa
3, Wifi

Probably unnecessary, a 1x ESP32, 1x E5 board would solve most possible use cases.

Should probably take advice from @geeksville or someone else who knows what they’re talking about before doing any work though.

Egress LoRa??? do you mean output?

To add WiFi we can use the esp8266 as a WiFi “card” for the E5. But I imagine a super low power node, without WiFi and bluethoot, the only interface whit the word it’s via the mesh and a UART to program it.
