Hobbywing RPM + Telemetry Signal Coupler Module (Scm)

The Hobbywing RPM & Telemetry Signal Coupler Module (SCM), part number HW30850200, is a compact interface that helps ensure reliable RPM and telemetry communication between an ESC and a receiver or flybarless (FBL) unit. It addresses common signal-level mismatches and interference that can prevent data from being read correctly.

Overview

Designed for dependable data transfer in heli and similar applications, the SCM sits between the ESC and control electronics to stabilise communication. It can help where:

• The ESC’s RPM signal is not recognised by a flybarless device
• The telemetry GND level from the ESC does not match the flybarless device’s GND level
• Telemetry signals are affected by electrical noise/interference

Suggested Compatibility

• Hobbywing Platinum V4 ESCs
• Other-brand ESCs that provide RPM/telemetry outputs
• Flybarless devices such as the MSH Brain series
• Receivers requiring matched telemetry ground levels

Specifications

• Size: 45.4 x 11.6 x 7.7 mm (L x W x H)
• Weight: 2.1 g
