usbroway RX74 24V 2.4G Bluetooth Receiver Kit

Receiver kit for 24 V ride-on cars

The usbroway RX74 kit provides a 2.4 G Bluetooth receiver and matching TX20 remote for children’s electric ride-on vehicles that run on a 24 V system. It is designed as a direct replacement for the original control box when the factory unit fails or is lost. The seven-pin four-sided socket must match the existing connector on the vehicle. Buyers who need a different voltage or a different pin layout cannot use this kit.

Behaviour during extended play sessions

The receiver operates on the 2.4 G band and maintains the link while the car is driven continuously around the yard or pavement. No thermal data or duty-cycle limits are supplied, so sustained performance under heavy load cannot be quantified. The kit is intended for typical intermittent use by children rather than constant high-current draw. Builders who require documented continuous-current ratings should look elsewhere.

Installation and common issues

First use requires a frequency-matching step between the remote and the receiver before the vehicle will respond. The seven-pin plug must align with the vehicle’s socket; a mismatched connector is the most frequent reason the kit appears not to work. Installers who cannot verify the exact model number on the old box risk fitting an incompatible unit.
