Product overview
The CADDX Alink is a handheld radio controller for FPV drone operation and wired simulator practice, including Liftoff and DRL. Its control architecture combines an AT32 F413RCT7 main chip, a built-in ELRS 2.4GHz radio module and the CRSF protocol, with maximum RF output of 100mW (20dB). Ten channels are available, including four assigned to the sticks. Full-bearing Hall-effect stick assemblies provide the primary flight inputs, supplemented by one latching button, two momentary buttons, two three-position rocker switches and a scroll wheel.
The controller measures 158 × 108 × 58mm, subject to manual measurement error, and weighs 180g ±5g. Four indicator lights and a buzzer provide status feedback. A single USB Type-C port handles charging and simulator communication, while an internal 1s 1000mAh LiPo battery powers the unit within a DC 3.50–4.20V operating range. Charging takes approximately 90 minutes, with charging specifications of 5V/1A/3.50W. The supplied package contains one Alink controller, one power cable and one instruction manual.
