BAYCKRC C3 Dual-Band Fusion Receiver – 100mW Gemini RX
Single-sided dual-antenna system supporting dual-band signal fusion.
Designed for ExpressLRS pilots who want the ultimate in reliability, range, and flexibility. The BAYCKRC C3 combines tri-band support, powerful backhaul output, and multiple diversity and Gemini modes in an ultra-light 1.6g package.
Features:
- ExpressLRS System Receiver – advanced long-range control performance.
- Tri-Band Support – works with 868MHz / 915MHz / 2.4GHz systems.
- Dual 100mW Backhaul Power – strong and stable signal at all supported frequencies.
- 8 Switchable Receive Modes – choose between diversity, Gemini, and dual-band GeminiX.
- Ultra-Compact Design – single-sided PCB layout, only 17 × 26.5mm and 1.6g.
- KDS 32MHz TCXO – temperature-compensated crystal oscillator for ultra-stable frequency performance.
- High-Performance Processor – ESP32-C3, RISC-V 32-bit, 160MHz, with 4MB Flash.

Let customers speak for us
Was easy and good fit for my Era mini 3.5 drone 😜
Works great and matches expectations
Puikūs, gerai laikosi,lengvai užsideda. 10/10
Puikūs įrankiai, daug skirtingų galvučių
Labai gera antena, jaučiasi ryšio kokybės pagerėjimas
pirkau ant tinywhoop signalui gerint, siek tiek ilgesne nei tikejaus bet tiko
