Jumper JP4-in-1 Module
The Jumper JP4IN1 Module features the CC2500, NRF24L01, A7105 and CYRF6936
RF Chip modules all integrated on one board. This module can convert
standard PPM signals form module equipped radios in to the RF protocols used
by most radios in the market today (See RF Chip data below). This module is
plug and play with module equipped radios in the FrSKY series and requires
no complex wiring or “hacking” to get running. The module is a great way to
improve the enjoyment of your flying experience, using a better radio such
as the FrSKY Taranis series rather than the low grade radios commonly
included with most kits offers an night and day difference in performance.
The Jumper JP4IN1 module is also upgradable via USB input
