Comment on I want to learn designing IOT PCBs (with 2.4Ghz wireless)
ntn888@lemmy.ml 1 week agoI’m getting 1W 433 modules for like $15 now
haha I guess cheap is relative :) I was considering parts at 4 to 5$ range. But i’m talking about low power ble/zigbee etc…

Well, with some of my telemetry I’m trying to punch 10 klicks so there’s no kill like overkill. The little SX1278s are inexpensive and they’re legal power, and there’s plenty of examples out there for them.
I kinda like the UART design on the e32s though, but it was a struggle getting the library that uses them to work, and there’s little tricks like having to initialize the serial independent of his constructors, you read the code and it supposedly opens the serial, but it doesn’t work if you don’t do it beforehand, at least with the modules I was using.
