Documentation on hardware differences between versions #50

Closed hsand closed 3 years ago

Does anybody know the specific differences between the 868/915/443/923 versions of the T-Beam? The SX1276 spec claims to support 137MHz to 1020MHz. Is there any reason these boards couldn't transmit on the entire frequency range, assuming it was paired with an appropriate antenna?

Did some research, and I'll assume the RF filters in the different modules are tuned to reduce harmonic noise on unwanted frequencies. Hence different modules, even though the use the same chip. Closing :)
