Overview
The Flysky INr8-8D is a 2.4GHz 8-channel RC receiver using the AFHDS 3 protocol, featuring integrated lighting control via D1–D8 outputs. It uses a single-antenna, bidirectional transmission system and supports 4 Newport function connectors plus 8 function connectors.
Using the D1–D8 connectors as an example, the INr8-8D can be used as a receiver with lighting control functions, as a standalone LED light unit compatible with third-party receivers, or as an S.BUS/i-BUS out/PPM signal to PWM converter compatible with third-party receivers.

Details

Built for Noble NB4-series radios, the INr8-8D combines an 8-channel AFHDS 3 receiver with dedicated D1–D8 LED lighting control outputs.

Dedicated ports simplify wiring: CH1–CH8 for control signals plus labeled D1–D8 outputs for common RC car lighting functions.

The included BVD harness connects to the battery leads to provide battery voltage detection through the receiver’s BVD/VCC port.

Retail packaging includes printed details and protocol markings for quick identification in your parts box.

Compact receiver body with a single antenna lead, plus MODE and BIND buttons for setup and pairing.

Clear side labeling helps keep channel and lighting connections organized during tight chassis installs.

Ports are arranged for clean cable routing, and the antenna length is easy to position away from interference.

In the box: INr8-8D receiver, BVD harness, printed manual, QC card, and Flysky sticker sheets.

At 41 × 28.3 × 13.3 mm, the INr8-8D fits most RC car receiver boxes while keeping full 8-channel capability.
