Cool - with the right settings you can get MCC LMIC 3.3.0 on to that with room for a couple of sensors. Sadly I can’t find any 3216’s at present as I was going to make a design for that.

It’s not really an ATtiny, but it is quite compatible and not expensive:

AVR128DB28 PCB with RFM95

I made a PCB for the STM32 about 4 years ago: https://www.thethingsnetwork.org/labs/story/a-cheap-stm32-arduino-node, but because these boards are hard to get nowadays I recently designed a PCB with the AVR128DB28. These are inexpensive (about 2€) and have a modern architecture, compatible with the ATtiny3216 and ATtiny1614, but with 128 kBytes flash. [AVR-LORA] My design is an SMD design (large 1206 but easy to change to 0805) because I have recently overcome my fear of hand soldering these c…
