It's - designed to fit in a 24mm coupler tube. - - You usually don't need to configure EasyMini at all; it's set - up to do dual-deployment with an event at apogee to separate - the airframe and deploy a drogue and another event at 250m - (820ft) to deploy the main. Install EasyMini in your airframe, - hook up a battery, igniters and a power switch and you're - ready to fly. - - === EasyMini Screw Terminals - - EasyMini has two sets of four screw terminals near one end of the - board. 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: - - .EasyMini 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 EasyMini - - There are two possible battery connections on - EasyMini. 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 EasyMini 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 EasyMini - - 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 EasyMini - 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 EasyMini, 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 EasyMini - - 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.
