It was - designed to fit inside an 18mm air-frame tube, but using it in - a tube that small in diameter may require some creativity in - mounting and wiring to succeed! Since there is no - accelerometer, TeleMini can be mounted in any convenient - orientation. The default ¼ wave UHF wire antenna attached to - the center of one end of the board is about 7 inches long. Two - wires for the power switch are connected to holes in the - middle of the board. Screw terminals for the e-matches for - apogee and main ejection charges depart from the other end of - the board, meaning an ideal “simple” avionics bay for TeleMini - should have at least 9 inches of interior length. - - === TeleMini v1.0 Screw Terminals - - TeleMini v1.0 has four screw terminals on the end of the - board opposite the telemetry antenna. Two are for the apogee - and two are for main igniter circuits. There are also wires - soldered to the board for the power switch. Using the - picture above and starting from the top for the terminals - and from the left for the power switch wires, the - connections are as follows: - - .TeleMini v1.0 Screw Terminals - [options="header",grid="all",cols="2,3,10"] - |==== - |Terminal #|Terminal Name|Description - - |1 - |Apogee - - |Apogee pyro channel connection to pyro circuit - - |2 - |Apogee + - |Apogee pyro channel common connection to battery + - - |3 - |Main - - |Main pyro channel connection to pyro circuit - - |4 - |Main + - |Main pyro channel common connection to battery + - - |Left - |Switch Output - |Switch connection to flight computer - - |Right - |Switch Input - |Switch connection to positive battery terminal - |==== - - === Using a Separate Pyro Battery with TeleMini v1.0 - - As described above, using an external pyro battery involves - connecting the negative battery terminal to the flight - computer ground, connecting the positive battery terminal to - one of the igniter leads and connecting the other igniter - lead to the per-channel pyro circuit connection. Because - there is no solid ground connection to use on TeleMini, this - is not recommended. - - The only available ground connection on TeleMini v1.0 are - the two mounting holes next to the telemetry - antenna. Somehow connect a small piece of wire to one of - those holes and hook it to the negative pyro battery terminal. - - Connecting the positive battery terminal to the pyro - charges must be done separate from TeleMini v1.0, by soldering - them together or using some other connector. - - The other lead from each pyro charge is then inserted into - the appropriate per-pyro channel screw terminal (terminal 3 for the - Main charge, terminal 1 for the Apogee charge). - - === Using an Active Switch with TeleMini v1.0 - - As explained above, an external active switch requires three - connections, one to the positive battery terminal, one to - the flight computer positive input and one to ground. Again, - because TeleMini doesn't have any good ground connection, - this is not recommended. - - The positive battery terminal is available on the Right - power switch wire, the positive flight computer input is on - the left power switch wire. Hook a lead to either of the - mounting holes for a ground connection. |
