To understand the significance of the update, we must first look back. The original HSB133 receiver was released as a mid-tier, dual-band (2.4GHz and 5.8GHz) capable receiver designed primarily for long-range drone systems and ground station vehicles. It was praised for its diversity antenna system and low latency.

However, over the last 18 months, users reported three consistent pain points:

Enter the HSB133 receiver updated. Following thousands of user feedback tickets and bench tests, the manufacturer went back to the drawing board. The result is not merely a patch but a significant evolutionary leap.


Solution: The updated receiver has a high-resolution ADC. However, if your flight controller’s ground is noisy, you will see noise. Add a 1000µF low-ESR capacitor to your PDB (Power Distribution Board) or use the dedicated TELE_GND pad if your FC has one.

With a directional antenna on the transmitter and the HSB133 receiver updated using its diversity antennas, the receiver achieved a 18.2km range with a clear line of sight. The updated telemetry reported back with only 12ms latency at that distance.

Verdict: The updated hardware provides approximately 40-60% better range in noisy environments compared to the original.


Even though this is the updated hardware, always check for the latest firmware.
