LightFin Nano
6-Channel ELRS Stabilized Receiver for Micro RC Aircraft
Overview
LightFin Nano combines an ELRS 3.x receiver, a 6-axis IMU, channel mixing, and stabilization on an ultra-light board. It can drive either micro servos or brushed motors, making it a compact control solution for micro fixed-wing aircraft and other lightweight models.
Core Features
- 6-channel output: Supports six micro-servo connections
- Brushed motor drive: Supports four brushed motor outputs shared with the servo connections, up to 5A per channel
- 6-axis motion sensing: Equipped with a domestically produced 6-axis IMU
- ELRS 3.x: Compatible with the open ExpressLRS 3.x protocol
- Mixing and stabilization: Supports 6-channel mixing plus rate and attitude stabilization modes
- Convenient tuning: Adjust PID parameters from a transmitter or the web interface
- Web updates: Upgrade firmware through the web interface
- Ultra-light design: Approximately 2.5g with all connectors, or 1g without connectors
Typical Uses
- Micro fixed-wing and indoor RC aircraft
- Lightweight models driven by servos or brushed motors
- DIY aircraft requiring channel mixing, rate stabilization, or attitude stabilization
- Micro RC projects built around the open ELRS protocol
