The BAYCK ELRS 5CH PWM receiver is a game-changer for traditional RC pilots. While most ELRS receivers require a flight controller (UART), this unit outputs standard PWM signals directly to your servos and ESC.
Built on the powerful SX1281 + ESP8285 chipset, it delivers the massive range ELRS is famous for, even in high-interference environments. One of its standout “pro” features is the external voltage telemetry (VBAT) support. With ELRS firmware 3.0+, you can feed up to 34V directly into the receiver to monitor your flight battery voltage in real-time on your radio—no extra sensors required.
Key Performance Highlights:
-
Direct Servo Control: 5 physical PWM channels allow you to plug in servos and ESCs directly, making it ideal for fixed-wing planes, boats, and cars.
-
Integrated Voltage Telemetry: Supports up to 34V voltage return, allowing you to monitor your main battery levels and set low-voltage alarms on your transmitter.
-
Wi-Fi Configuration: No more complicated button sequences. Simply let the receiver sit for 60 seconds, connect to the “ExpressLRS RX” Wi-Fi hotspot, and adjust your PWM settings, failsafes, and refresh rates from your phone or PC.
-
Ultra-Lightweight: At just 4.7g (including the antenna), it adds virtually no weight to your build, perfect for small gliders and weight-sensitive aircraft.
-
Dual Protocol Support: While it excels at PWM, it also supports CRSF output, giving you the flexibility to use it with a flight controller if your needs change.
