FCC Technical Details of the LemonRx Module

Post by Mike_K »

For anybody who is interested in reading the FCC report on the LemonRx 2.4GHz transmitter modules, the details can be found with the link below:

https://apps.fcc.gov/oetcf/eas/reports/ ... TBKDSMPSDR

What I found most interesting is the internal photo's page, LemonRx has used an STM32F103C8T6 processor (commonly used for the Arduino blue pill boards), an A7127 2.4GHz transceiver (part of the A7105 family) and a CC2592 2.4 GHz range extender (amplifier). So they are using the A7127 (similar to an nRF24L01+) to emulate a CYRF6936, one can only assume that it could also be programmed to be a "multi-protocol" module with many other popular protocols if LemonRx so wished, all in a tiny package. And it would be cheaper for them to produce as it only has one rf chipset, not four.
