315/433M Super-heterodyne Wireless RF Receiver
KL-RF211B is a general 3V radio receiver that operate at 315/433.92MHz with typical sensitivity of -115dBm.As a superheterodyne receiver for OOK and ASK modulation up to 10kbps. Any one-off-four filter bandwidths may be selected externally by the user in binary steps, from 1.25kHz to 10kHz. The user need only configure the device with a set of easily determined values, based upon data rate, code modulation format, and desired duty-cycle operation
What you want to know?
Q1: What's output signal ? A1: It outputs TTL .
Q2: Can you provide related certification like CE/FCC ? A2: Yes,we designed and produced it under their directive.
Q3: What's working mode? A3: Default momentary ,toggle and latch is optional.
Q4: Will it be interfered by around same frequency signal? A4: Our receiver has certain anti-interference ability.
Q5: Why call it for fixed code receiver? A5: It only can work with fixed code remote.
Q6: Can we change supply voltage for 9Vdc ? A6: Of course ,we support this service.
Q7: Can we print our model number on PCB ? A7: Yes. please confirm this with us before placing..
Q8: Can we customize size of PCB of Pin ? A8: Yes ,we support
Q9: Why it can't work with our remote ? the frequency is same. A9: Besides frequency ,oscillation resistance and address code should be matched . Q10: I didn't know what's oscillation rsistance and address code . A10: Please contact us .
