About Tax

For countries other than USA, we only charge product cost + shipping cost, no tax.

Orders from US customers are adjusted according to different shipping channels:

1. For Standard Express Order: We charge【product cost + shipping cost + part of tax】this rate is only applicable to shipment from China warehouse.
(Since the tax is charged according to the declared amount, we have filtered the most suitable solution, and it is most likely that this shipping way does not need you to deal with the customs duty, but it is not absolute)

2. For DHL Order: We charge【product cost + shipping cost】no any tax, tax need you to pay attention to the local policy changes, when the parcel arrives at the US customs, deal with the tax matters by yourself.

----------

The above content is only for charging reference on lilygo.cc website, the specific tax situation still depends on the local country's policy requirements, once the parcel is sent out, you need to keep an eye on its status, and to assist in handling it as needed when it arrives at the local customs, we will also follow up during the process, if you have any

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.
