RRC2+ Altimeter
Couldn't load pickup availability
The RRC2+ is a barometric dual-deploy altimeter, with a feature set for beginners and experts alike. The unit is extremely small and very easy to install and operate. It's programmed using a very straightforward DIP switch configuration method. No User Manual or documentation is required on the field, as all the switch settings are printed right on the altimeter itself. The RRC2+ epitomizes the "buy it and fly it" altimeter, with a price point that your rocketry budget will appreciate as well.
Specifications
Architectural Features
· 16MHz 16-bit MSP430 Series mCU
· 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.
Operational Range
· 40K MSL (Sensor system is 100K MSL capable)
Note: The RRC2+ uses an electrolytic brownout capacitor. Electrolytic capacitors have (semi-)liquid dielectrics, which can boil off in vacuum.
Power Requirements
· 3.5 VDC to 10.0 VDC / Optimized for 9V battery power
· 6ma @ 9V quiesecent / 35ma @ 9V during piezo and LED operation
Physical Properties
· Length 58mm (2.28")
· Width 23.5mm (0.925")
· Weight ~10 grams
· Mounts via 2" hole centers (same as RRC2-mini)
Output Events
· Drogue / Main
· 5A @ 9V current sinking
Flight Data Recording
· Reports peak altitude "post flight" and saves this value to EEPROM
