I started following this project recently as I am very interested in this
application. I am a chip design engineer and would like to collaborate.
Please let me know how to proceed.
Best regards,

Hi all,
I finally have some free time to work on the next Disaster-Radio dev
board. Before I get started, I wanted to double check the major components
with everyone:
* ESP32
* 2x LORA IC
* SD FLASH CARD
* CN3791 MPPT solar charger
* 18650 LiPo Battery
I'm considering ditching modules for this next build and using IC's
directly on board for the ESP32 and Lora IC:
* ESP32 -

* LORA -
https://www.digikey.com/product-detail/en/semtech-corporation/SX1273IMLTRT/…
This will definitely lower costs and allow a bit more flexibility. I'm not
sure if the RFM95 is available directly as an IC. Is there any issue with
using the SX1273 instead?
I'll be at hardware hacking tomorrow night too, if anyone has any ideas or
wants to brain storm.
