12-Channel CRSF to PWM Adapter Board – DC5V ELRS RC Module
Gaqqee 12-Channel CRSF/ELRS to PWM Adapter Board
Upgrade your RC build with the Gaqqee 12-Channel PWM Adapter Board — the plug-and-play signal converter that bridges CRSF and ELRS protocols to standard PWM outputs. Whether you're flying fixed-wing aircraft, multi-rotor drones, or RC cars, this compact module delivers rock-solid signal conversion with zero external power hassle.
Key Features
- 12 PWM Outputs: Full 12-channel PWM output — ELRS 3.0.0+ firmware supports all 12 proportional channels for maximum servo and ESC control flexibility.
- CRSF & ELRS Protocol Support: Seamlessly converts CRSF and ELRS signals to PWM, compatible with mainstream ELRS receivers right out of the box.
- Integrated 5V BEC Power Supply: Built-in BEC delivers stable 5V output, eliminating the need for a separate power source and simplifying your wiring setup.
- 6S Battery Voltage Telemetry: Supports telemetry voltage feedback (RxBt) for batteries up to 6S, giving you real-time power monitoring directly on your transmitter.
- Signal Indicator LEDs: Onboard CRSF signal acquisition LED indicators provide instant, clear visual confirmation of connection status at a glance.
- Low Power Consumption: Efficient design minimizes draw on your power system, extending flight or run time.
- Compact & Lightweight: Measures just 3.7 × 3.1 cm (including header pins), fitting easily into tight RC builds.

Frequently Asked Questions
Q: Is the ELRS receiver included with this CRSF to PWM adapter board?
A: No, the ELRS receiver is not included. This module is a signal converter/adapter board only. You will need to purchase a compatible ELRS receiver separately and connect it to this board to use the 12-channel PWM output.
Q: What firmware version does my ELRS receiver need for full 12-channel support?
A: Your ELRS receiver must be running firmware version 3.0.0 or higher to take advantage of all 12 proportional PWM output channels on this adapter board.
Q: Does this adapter board support battery voltage telemetry?
A: Yes! The board supports RxBt telemetry voltage feedback for batteries up to 6S. This allows you to monitor your battery voltage in real time directly through your CRSF/ELRS-compatible transmitter.
Q: Do I need an external power supply for this PWM adapter board?
A: No external power supply is needed. The integrated 5V BEC power supply built into the board provides stable power to your connected servos and devices, simplifying your overall RC wiring.
