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 - https://lcsc.com/product-detail/RF-Transceiver-ICs_Espressif-Systems-ESP32_C80134.html

 * LORA - https://www.digikey.com/product-detail/en/semtech-corporation/SX1273IMLTRT/SX1273IMLTRTTR-ND/5226771

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.

-Fitz
