Meshtasticd on pi zero 2 and 1 watt 915mhz Ebyte lora RF module

So I am interested in trying this, my goal is to run a 1watt RF module on a Pi. It looks like the Ebyte E19-915M30S is discontinued, so I was wondering if someone could recommend an updated module from Ebyte that they think SHOULD work?

There are some folks who have used the Ebyte E22-900M30S in this and the Hydra DIY targets. This should work, and currently remains in production.

There is also a newer high-power LLCC68 module from Ebyte which is also in production, but I’m not aware of any Meshtastic targets today that support the LLCC68. The E32-900M30S you linked should also, theoretically, be compatible.

or what requirements should I look for; non UART? SPI interface only? chipset requirements?

SPI-interface only; Meshtastic needs to be able to specify exactly what goes on in a LoRa frame, and Meshtastic does this through RadioLib today, which drives all the known LoRa chips through SPI for such fine-grained control. Supported micro-controllers today include the ESP32; nRF52 series; the RP2040 family; and some native Linux targets (meshtasticd). Theoretically, any RadioLib-supported LoRa chip, with its SPI connection directly exposed to the microcontroller, should be compatible…

The waveshare lora module uses SX1262 , so could the SX1262 option in the link below work?

A cursory glance through Waveshare’s catalog suggests that the RP2040-based device, the Core1262, the LoRaWAN/GNSS hat, and the RP Pico LoRa hat would be compatible. Most of the other products I saw were UART (i.e. has a small microcontroller running its own firmware to control the LoRa chip / determine framing), though I keep having to edit this post because their product categorization/search page is hot garbage.
