MSRC – Multi Sensor Telemetry for RC (RP2040)

MSRC is a lightweight, low-cost, and highly flexible telemetry system for RC models, based on the RP2040 microcontroller.

It allows you to collect data from multiple sensors and transmit it to your receiver using a wide range of telemetry protocols. MSRC is a DIY alternative to commercial solutions, offering significantly reduced weight and cost while maintaining high flexibility and expandability.
