Lora boards question for small project

Hello!

I want to create a small project with 4 LORA capable boards. 3 of them will each be connected to a couple of sensors and the 4th will act as a gateway receiving through direct LORA sensor data from the other boards and send it to a web server with WiFi. The data will be then displayed in Grafana.

I'm not trying to create something really fancy, this will mostly be just a working prototype.

I did some research and I pretty much ended with 3 board variants:

PYCOM LOPY 4
TTGO (T-beam or the short variant)
Heltec

The PYCOM seems a lot more advanced but it is more expensive than the rest and you have to buy the antennas and the extension module for programming separately. Also, I didn't use Micropython before so that may be a problem.

I'm not really good at C++ but I tinkered around in the Arduino IDE with a Uno, sensors and a screen so I'm not a complete noob.

Since the price is a couple of times higher than the usual Arduino/ NodeMCU I'm afraid of choosing the wrong boards and then to not be able to find some proper documentation/ examples to finish this project,

If you know of similar projects that I can use as inspiration please share them.

Any suggestion about what boards should I choose will be greatly appreciated.

Thank you very much!

GUEST POST: The Example We Set

By David Kier

“…in all things show yourself to be an example of good deeds, with purity in doctrine, dignified, sound in speech which is beyond reproach, in order that the opponent may be put to shame, having nothing bad to say about us.” Titus 2:7-8 NASB®

In my early years at college, I met a few guys from out east who had brand new fancy cars and really nice clothes and wondered why they were at a small midwestern college.

More Government Spending Won’t Strengthen What’s Weak in America

The president returned to familiar turf inside the United States Capitol on Wednesday to meet with Democrat lawmakers to discuss the budget, a massive spending proposal that promises to plunge the country deeper into debt. 

Since we were kids, we’ve been told that money doesn’t grow on trees, but you wouldn’t know that from the way Congress has been doling out dollars of late. Based on media reports, the Senate majority are expected to ask for somewhere between $3.5 trillion and $4 trillion dollars for the upcoming fiscal year. 

Of course, contained within those trillions are vital and critical items – military spending to ensure our nation’s safety, infrastructure to keep America operational and, especially in the midst of a global pandemic, measures intended to protect our citizens’ health and well-being. 

Yet, also included are dollars many liberals and radicals want to “transform” America – i.e., turn upside down and inside out fundamental values and traditions that have distinguished the United States for well over two centuries. 

Sadly, there seems to be a prevailing philosophy in Washington these days that money will solve any problem, and the more money we spend, the fewer problems we’ll have. 

It’s just not true. 

Take for instance our ongoing battle to eradicate poverty. 

Since President Johnson declared a war on poverty in 1964, nearly $26 trillion in taxpayer funds has been spent to fight it.
