Overview
The FLYSKY PR01 is a 2.4GHz 16-channel micro ExpressLRS (ELRS) receiver designed for racing drones and other RC models. It features dual on-board ceramic antennas with antenna diversity, bidirectional communication, TCXO frequency stabilization, and CRSF/S.BUS data output for broad compatibility with modern flight controllers and RC electronics.
Key Features
- ExpressLRS 2.4GHz ISM with compatibility for ELRS protocol transmitters and RF modules
- Dual on-board ceramic antennas with antenna diversity for stable reception in challenging RF environments
- CRSF / S.BUS output for flexible integration
- 16 channels with 4096 resolution
- Refresh rate support: max 500Hz / F1000Hz, min 25Hz
- TCXO for frequency stability across temperature changes
- Firmware update methods: Wi-Fi update or wired serial update
- Wi-Fi mode behavior: automatically enters Wi-Fi mode after 60 seconds of no signal; Wi-Fi name: “ExpressLRS RX”
- Binding: 3-cycle power binding mode
