It could be that a PCB that integerates both of those two modules would cost less.
Also check out my question on StackExchange regarding the radio circuitry. The given answer is pretty informative.
- A great guide for implementing USB-C in your KiCad projects - I highly recommend taking Phil's Lab PCB design courses. It helped me a lot.

Elora vision: common questions
What microcontroller does the Elora vision use?
The Elora vision is built around the SX1276IMLTRT, from the STM32 family.
How big is the Elora vision PCB?
The Elora vision measures 40 × 39 mm, has 4 copper layers and is 1.59 mm thick.
How many components are on the Elora vision?
70 components, from 60 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Elora vision design files?
From the aminjahanpour/elora_vision_pcb repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Elora vision design in my own project?
The repository has no license, so all rights stay with aminjahanpour. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Elora vision without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
