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. Screw +	terminals for the power switch are located 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 v3 Screw Terminals + +		TeleMini v3 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. Another two +		screw terminals are located in the middle of the board +		for the power switch.  Using the +		picture above and starting from the top for the pyro terminals +		and from the left for the power switch terminals, the +		connections are as follows: + +		.TeleMini v3 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 v3 + +		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 v3 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 v3, 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 v3 + +		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. + +	=== TeleMini v1 + +		TeleMini v1 is the earlier version of this product. It +		has a lower-power radio, less storage, no beeper and +		soldered-in wires instead of screw terminals for the +		power switch. + +		.TeleMini v1 Board +		image::telemini-v1-top.jpg[width="5.5in"] + |
