Overview
FrSky Archer Plus R6 Lite / SR6 Lite is a 2.4GHz telemetry receiver series with Archer Plus (AP) enhancements, including improved anti-RF-interference capability for more solid RF performance. These receivers support both ACCESS and ACCST D16 modes, with the RF protocol smart-matched during binding. In ACCESS mode, OTA wireless firmware upgrades are supported, along with additional telemetry and protocol options such as configurable telemetry power and protocol switching (S.Port/F.Port/FBUS). (*Some features require the support of ACCESS and ETHOS.)
The AP Lite-series design provides 6 high-precision PWM channel ports and multiple function ports via SBUS In/Out, S.Port/FBUS, and AIN, using the included connector adapter cable for flexible system builds. Through an S.Port cable, the receiver can be connected to an S.Port-capable transmitter for firmware upgrade or to sensors for telemetry. When set to FBUS mode through the ETHOS system, FBUS-capable devices can be configured through ETHOS using Lua script tools, and the receiver can output 24 signal channels in total.
