FlySky FS2A 4CH Mini Receiver (AFHDS 2A, PWM)

The FlySky FS2A is a 4-channel AFHDS 2A receiver with individual PWM outputs, sized for RC cars, boats, small fixed-wing models and simple projects where each servo or ESC takes its own signal lead. At about 0.9 g and 25 × 11 mm it fits into spaces a full-size receiver cannot.

Key features

• Binds to FlySky AFHDS 2A radios including the FS-i6, FS-i6X, FS-i6S, FS-TM8, FS-TM10 and FS-i10
• Four PWM channels: plug servos and ESCs straight in, no decoder or mixer needed
• Wide 3.3–10 V input runs from a standard 5 V BEC rail or directly from a single cell
• Draws just 20 mA, with -92 dBm receive sensitivity

Set the transmitter to AFHDS 2A before binding; the older first-generation AFHDS mode will not link with this receiver. For a Betaflight, INAV or ArduPilot flight controller that expects a single-wire serial input such as iBUS or SBUS, choose a serial-output receiver instead, as the FS2A is built for direct PWM control.
