My New Favorite Mesh Node

This node from Lilygo is a great option for mesh firmware. The solid/soldered SMA connector is a big improvement over pigtail connectors. The ESP32 platform provides plenty of memory and flash space. I write firmware for these. Here are my thoughts on the various components:

E-Paper screen
It does take a few seconds and flashes a few times to refresh, but the fact that it keeps the last display, even with power cut could be very convenient if you're using a mesh broadcast system and want your message to persist on the screen, even with a dead battery. I love this display. The screen does fine in cold temperatures as well (0-10f), in case that matters to you.

SX1262 transceiver
Already known as a good performer, no surprise here

SMA Connector
This is one thing that makes this unit really stand out in my mind. Multiple soldered ground connections. You don't have to worry about the connector working loose after so many times of swapping antennas. You don't have to worry if your pigtail wire is running/looping past a component that might cause interference.

SD card integration
fast enough and stable, but be aware it's very picky about which cards work

Qwiic port
I use this for I2C, for GPS and DS3231 realtime clock. this was a great choice by Lilygo, tons of options (see sparkfun)

ESP32
Although some people describe ESP32 as being a bit of a power hog, I have to say that's necessarily true. It does use more power than slower platforms, but I find it's GPS often that really eats up the power. I have versions of my firmware that can make use of RTC and not need GPS for time-related functions, and without GPS, a simple/cheap/small solar panel can easily keep this thing running, even where I live in the midwest winter's sad overcast sunlight. I think the speed/memory tradeoff is worth the extra power consumption. Now, it's true, you're not going to run this thing off a coin cell battery.

Amp Compatability
I have one of these running with a 1 watt bidirectional amp powered by solar under the back seat of my truck. I also have another one running as my home "base station" through a 20 watt bidirectional amp. Both of these perform extremely well. I can't wait for warmer temps to explore and figure out exactly how far this signal is reaching. I know it's at least 14 miles where line of sight is fairly good. I would bet it's reaching much farther than that, but time will tell.
