RFM23-S1 – 868MHz pure fun
(click für größeres Bild)
Samstag Abend hab ich bei OCTAMEX(.de) 3 RFM23-S1 (868MHz) Funkmodule gekauft. Die waren auch prompt heute (Dienstag) da.
Diese Module haben für den Preis von knapp 5€ erschreckend viele Features. Bin schon echt drauf gespannt diese Module zu benutzen, bis jetzt fehlt mir allerdings noch die passende Idee…
hello I need help with this unit I do not know how to connect it to USART transmit from pc to pic and I have the preograma I want to convey but I have no idea how to do the conexion these modules
you can help me please
Sorry, HopeRF doesn’t prefer „downward compatibility“ as a product specification. The RFM22B/RFM23B communication is fully different. But there is an example on the site, and you can search for RFM22 for example avr code on Internet (it is the same exept output power and additional power amp pins).
Nope, I haven’t tried them yet. But AFAIK there is a library for AVRs using the RFM12 modules, which should work for the RFM23 as well due to downward compatibility….
Have you tired use this module with MCU AVR?
