Both the full adapter and PCBA only are Beta FPV's most recently updated versions.
With the use of micro to nano module adapter, a nano tx module can work on transmitters with JR module bay (aka Micro module port) easily!
The Micro to Nano Module Adapter (PCBA) is available for those who can print the case for themselves. You can download the adapter case STL file on Beta FPV's technical support page.
This adapter is a perfect match for the BetaFPV Nano ELRS module in either 900MHz or 2.4GHz!
