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: + + [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. |
