10mW FSK Transceiver With Wide Frequency Support, SPI Interface And High Speed Data Transfer Based On CC1101

This is a transceiver module based on the CC1101 transceiver chip from Texas Instruments that can be programmed via SPI interface and sends/receives in the 387-464MHz range. It comes with an SMA terminal to attach an external antenna. The theoretical distance this device can cap is estimated at 500m-700m.

It uses FSK modulation which is based on frequency modulation (FM). It is incompatible with simple remote controls which use ASK (AM).

The E07-M1101D is a good choice when you want to design your own high speed two-way data transfer system, i.e. to send sensor data or text messages.

This board is also known as AS07-M1101D and AS07-M1101D-SMA

Frequency Range And Channels

The board can send and receive in a frequency range of 387-464MHz.

Its maximum transmitting power is +10dBm/10mW, and the receiver sensitivity is good with -112dBm. In free line of sight, distances of roughly 500m can be bridged.

Pin Tag Description
1 GND negative voltage
2 VCC +3.3V
3 GDO0 I/O
8 GDO2 I/O


There are different versions of this board available: the antenna is either fixed to the board (coil antenna), or a SMB connector allows connection of an external antenna.


This board uses the SPI interface to communicate with a microcontroller.

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.


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.
