Great Lower-Power Addition to Mesh Cluster - Solid SMA Connector

The T3S3 has proven to be quite stable within my mesh cluster (LoRa 915). I used it as a base station node for about 30 days, also connected to a bi-directional (1 watt) amp, running to a roof-mounted antenna. The form factor is nice and small, while still providing ample memory and an SD slot for however much space you need.

I ported firmware designed for the T-Beam supreme over to this smaller T3S3 for comparison. I also tested the grove connector with both GPS modules and with a DS3231 I2C module. Both types of modules performed solidly over I2C. I didn't try the UART grove plug.

Positives:
* Small form factor
* Solid/soldered SMA connector for LoRa
* very competitive price (well...as of feb 2025)
* fast ESP32 performance
* Less power usage vs some options that include GPS

Negatives
* less memory/flash available than t-beam supreme
* Only one functional button, so use it wisely
* small screen, use it wisely
* I have not seen many 3d printable enclosures, but maybe I've missed them

What I can report works well
* The board is very stable. It never reboots unexpectedly and can handle simultaneous use of flash/sd/screen/LoRa
* LoRa signals are very good for tx and rx
* Works very well with 1 watt, 4 watt, and 20 watt bidirectional amps
* SD card works fine with fat
* Flash works well with spiffs
* sx1262 is a solid performer, as we already know
* grove port is stable for IIC

I did zero testing of wifi/bluetooth with this, so I can't report on that.

All in all, if you want to play around with esp32 and LoRa, this is a great option.
