is rf 433mhz ask module serial or ttl compatible?

[sunnystar]

the simple and cheap RF 433mhz ASK module is serial or ttl/cmos compatible?

 

[betwixt]

They are all serial compatible to be able to send data.

Whether it is TTL or CMOS comapatible depends on the actual design but if it runs from a 5V supply it almost certainly is.

The 433 MHz ASK transmitter modules work from 3V to 12V but I don't know whether 12V can be given to DATA pin or not. You can provide 12V for VCC and %V TTL from uC to DATA pin of RF module (Transmitter). Providing 12V power will increase the range of transmission. For 3V I have obtained 40 ft transmission.

Is your RF modules like this ? They also come in Red color (Red color PCB).
