The RRC3+ System has many roots that were originally planted in an older legacy project started back in 2003 dubbed the 'mPAC'. This project never got much beyond the concept and prototyping stages, however it laid the groundwork for many of the fundamentals used by the RRC3 system today. It's only appropriate that the RRC3 inherit the original mPAC "Archie" logo.

The Rocket Recovery Controller 3+ (RRC3+) is a barometric dual-deploy altimeter, with the features of high-end units, at the cost of those with a more modest feature set. In addition to basic dual-deploy capability, the RRC3+ is a multi-flight recording unit, allowing you to fly all day, without the need to stop and download data in between flights.

The RRC3+ also provides a third, highly flexible and programmable 'Auxiliary' output which can provide staging, airstarts, backup events, and a host of other applications. The RRC3+ can also support real-time data streaming capabilities in flight for our RTx telemetry system or for interface with other custom control or downlink radio systems.

Despite this unrivaled suite of intrinsic capabilities and expandability, the RRC3+ still maintains its simple "buy it and fly it" operations. You can literally attach a battery and fly it "dual-deploy" out of the box.

Newly incorporated features of the RRC3+ include:

Measures only 2.56" (65mm) x 1" (25.5mm) and mounts identically to the RRC2+ and RRC2L
Impervious to Lithium Battery discharge current using upgraded "IntelliFET" output events
Upgraded 4A capable "IntelliFET" Aux output for enhanced staging or cluster ignitions
Supports all m3 Components (LCD Terminal, UDC interface, Bluetooth) and RTx Tethering
Still 9V Alkaline battery capable and button programmable

Specifications

Architectural Features
· 16MHz 16-bit MSP430 Series mCU
· 4Mbit SST Flash Memory
· MSI MS5607 Pressure sensor

Note: This high resolution altimeter sensor has a 24 bit ΔΣ ADC, with internal factory calibrated coefficients which provide a precise digital 24 bit pressure and temperature. The RRC3 design also provides a dedicated "baro-only" regulated power system and applies other noise reduction techniques to further accurize pressure data.
