This is called “LoRa Node 151”
https://heltec.org/project/lora-node-151/
Conflicting deep sleep specifications: 1.8uA and 2.5uA (but either should be fine 
)
(Is that an AMS1117 regulator 
or MOSFET?)
STM32L151 (no Arduino support).
“LoRaWAN example is restricted technical data, it will become downloadable after purchase” - bit odd
Yes, and:
“you can find it in your account page (Didn’t buy this product from our website or from a reseller? You can contact your provider or Email us)”
My interest is the low current claims based on STM32L151CCU6 - didnt RAK811 use the same chip
Where is the ‘bargain part’? 
I’m sure you’ll find something that fits your definition of a bargain

If you wondered how the Boston Swing batteries fit into 18650 PCB mounts…
These are some really great cells and very robust too, all round metal case.
