APRS Engineering MIM/Mic-Lite Module
Features:
Complete 1200-baud, AX.25, TNC transmit operation.
Telemeters 5 analog signals (8-bit resolution) and 8
digital bits of data.
Telemeters GPS position if a GPS receiver is attached.
Can send any NMEA 0183 sentence.
Position reports are APRS compatible.
Transmits Beacon text and CW ID (20 wpm).
All transmissions are sent automatically at user-selectable
intervals.
All transmission types are individually enabled or disabled
by the user.
User-programmable digipeat path containing up to 8 hops.
All user selections (Call sign, digipeat path, transmission
intervals, beacon text, etc.) are stored in EEPROM and can be changed whenever
desired using the supplied PC software and your computer's serial port.
Provides capability for "Hold off" to ensure
the channel is clear before transmitting.
All components are surface mount except the PIC16C73
microcontroller which is in a socket for easy firmware upgrades. Size:
1.0" x 1.7".
May be powered by an unregulated supply (6.5-40 VDC)
or a regulated 5 VDC.
Current consumption is less than 15 mA. If the unregulated
supply is used, the on-board voltage regulator can supply an additional
85 mA for other user applications.
