It adds more -	on-board data logging memory, a built-in USB connector and -	screw terminals for the battery and power switch. The larger -	board fits in a 24mm coupler. There's also a battery connector -	for a LiPo battery if you want to use one of those. - -	=== TeleMini v2.0 Screw Terminals -	 -		TeleMini v2.0 has two sets of four screw terminals on the end of the -		board opposite the telemetry antenna. Using the picture -		above, the top four have connections for the main pyro -		circuit and an external battery and the bottom four have -		connections for the apogee pyro circuit and the power -		switch. Counting from the left, the connections are as follows: - -		.TeleMini v2.0 Screw Terminals -		[options="header",grid="all",cols="2,3,10"] -		|==== -		|Terminal #|Terminal Name|Description -		|Top 1 -		|Main - -		|Main pyro channel connection to pyro circuit -	       -		|Top 2 -		|Main + -		|Main pyro channel common connection to battery + -	       -		|Top 3 -		|Battery + -		|Positive external battery terminal -	       -		|Top 4 -		|Battery - -		|Negative external battery terminal -	       -		|Bottom 1 -		|Apogee - -		|Apogee pyro channel connection to pyro circuit -	       -		|Bottom 2 -		|Apogee + -		|Apogee pyro channel common connection to battery + -	       -		|Bottom 3 -		|Switch Output -		|Switch connection to flight computer -	       -		|Bottom 4 -		|Switch Input -		|Switch connection to positive battery terminal -		|==== - -	=== Connecting A Battery To TeleMini v2.0 - -		There are two possible battery connections on TeleMini -		v2.0. You can use either method; both feed through -		the power switch terminals. - -		One battery connection is the standard Altus Metrum -		white JST plug. This mates with single-cell Lithium -		Polymer batteries sold by Altus Metrum. - -		The other is a pair of screw terminals marked 'Battery -		+' and 'Battery -'. Connect a battery from 4 to 12 -		volts to these terminals, being careful to match polarity. - -	=== Charging Lithium Batteries - -		Because TeleMini v2.0 allows for batteries other than -		the standard Altus Metrum Lithium Polymer cells, it -		cannot incorporate a battery charger -		circuit. Therefore, when using a Litium Polymer cell, -		you'll need an external charger. These are available -		from Altus Metrum, or from Spark Fun. - -      	=== Using a Separate Pyro Battery with TeleMini v2.0 -	 -		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. - -		To connect the negative pyro battery terminal to TeleMini -		ground, connect it to the negative external battery -		connection, top terminal 4. - -		Connecting the positive battery terminal to the pyro -		charges must be done separate from TeleMini v2.0, 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 (top -		terminal 1 for the Main charge, bottom terminal 1 for the -		Apogee charge). - -      	=== Using an Active Switch with TeleMini v2.0 -	 -		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. Use -		the negative external battery connection, top terminal 4 for -		ground. - -		The positive battery terminal is available on bottom -		terminal 4, the positive flight computer input is on the -		bottom terminal 3.  |
