RC Cockpit Telemetry Bridge
Real-time FPV driving bridge connecting PC sim rigs (Moza direct-drive, pedals, paddle transmission) to RC vehicles via dual ESP32 silicon nodes.
RC-Cockpit bridges professional PC sim racing hardware directly to physical radio-controlled vehicles. Drivers pilot 1/10 competition buggies or technical 1/24 rock crawlers directly from their full-scale sim cockpit—utilizing a Moza R12 direct-drive wheelbase, hydraulic load-cell pedals, and paddle shifters. An ultra-fast control pipeline decodes DirectInput signals in Python, sends them via serial to an ESP32-S3 transmitter node, and broadcasts raw ESP-NOW RF packets to an on-board vehicle ESP32-CAM node with sub-millisecond transmission latency.
