+== EasyMini
+
+       image::easymini-top.jpg[width="5.5in"]
+
+       EasyMini is built on a 0.8 inch by 1½ inch circuit board. It's
+       designed to fit in a 24mm coupler tube. The connectors and
+       screw terminals match TeleMini v2.0, so you can easily swap between
+       EasyMini and TeleMini.
+
+       === EasyMini Screw Terminals
+       
+               EasyMini 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:

+       === 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 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 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.
