AK-RXB59R

Superheterodyne ASK (Digital AM) Receiver With Great Sensitivity

The AK-RXB59R is a superheterodyne ASK receiver based on the CMT2220LS receiver chip that can pick up signals sent out by ASK senders and most remote controls.

The receiver does not come with a dedicated EV1527 encoder chip on board which makes the receiver versatile (it can receive any type of ASK-encoded data) but requires a separate microprocessor to decode the received data.

The board is very small and easily integrateable into DIY projects.

Frequency

The board exists both for 315MHz (US) and 433.92MHz (Europe, other regions). The frequency is determined by the crystal used.

By looking at the top of the crystal, the supported frequency can be implied:

Crystal frequency Receiver frequency
9.81563MHz 315MHz
13.52127MHz 433.92MHz

Pins

The board comes with pre-soldered four pins labeled on the back.

Pin Label Description
1 G GND (negative voltage)
2, 3 DATA Data Out
4 V 3.6-5.5V

Pins 2 and 3 are internally the same (inter-connected). There is just one data output that is HIGH when receiving a signal.

Make sure the power supply is properly filtered and carries no exceptional noise which could interfere and distort reception.

Antenna

The board comes with a pre-soldered coiled wire-antenna (22.6cm for 315MHz and 17cm for 433MHz).

Comments

Please do leave comments below. I am using utteran.ce, an open-source and ad-free light-weight commenting system.

Here is how your comments are stored

Whenever you leave a comment, a new github issue is created on your behalf.

  • All comments become trackable issues in the Github Issues section, and I (and you) can follow up on them.

  • There is no third-party provider, no disrupting ads, and everything remains transparent inside github.

Github Users Yes, Spammers No

To keep spammers out and comments attributable, all you do is log in using your (free) github account and grant utteranc.es the permission to submit issues on your behalf.

If you don’t have a github account yet, go get yourself one - it’s free and simple.

If for any reason you do not feel comfortable with letting the commenting system submit issues for you, then visit Github Issues directly, i.e. by clicking the red button Submit Issue at the bottom of each page, and submit your issue manually. You control everything.

Discussions

For chit-chat and quick questions, feel free to visit and participate in Discussions. They work much like classic forums or bulletin boards. Just keep in mind: your valued input isn’t equally well trackable there.
