5 EasyMini is built on a 0.8 inch by 1½ inch circuit board. It's
6 designed to fit in a 24mm coupler tube. The connectors and
7 screw terminals match TeleMini v2.0, so you can easily swap between
10 === EasyMini Screw Terminals
12 EasyMini has two sets of four screw terminals on the end of the
13 board opposite the telemetry antenna. Using the picture
14 above, the top four have connections for the main pyro
15 circuit and an external battery and the bottom four have
16 connections for the apogee pyro circuit and the power
17 switch. Counting from the left, the connections are as follows:

24 |Main pyro channel connection to pyro circuit
28 |Main pyro channel common connection to battery +

44 |Apogee pyro channel common connection to battery +
48 |Switch connection to flight computer
52 |Switch connection to positive battery terminal
55 === Using a Separate Pyro Battery with EasyMini
57 As described above, using an external pyro battery involves
58 connecting the negative battery terminal to the flight
59 computer ground, connecting the positive battery terminal to
60 one of the igniter leads and connecting the other igniter
61 lead to the per-channel pyro circuit connection.
63 To connect the negative pyro battery terminal to TeleMini
64 ground, connect it to the negative external battery
65 connection, top terminal 4.
67 Connecting the positive battery terminal to the pyro
68 charges must be done separate from EasyMini, by soldering
69 them together or using some other connector.
71 The other lead from each pyro charge is then inserted into
72 the appropriate per-pyro channel screw terminal (top
73 terminal 1 for the Main charge, bottom terminal 1 for the
76 === Using an Active Switch with EasyMini
78 As explained above, an external active switch requires three
79 connections, one to the positive battery terminal, one to
80 the flight computer positive input and one to ground. Use
81 the negative external battery connection, top terminal 4 for
84 The positive battery terminal is available on bottom
85 terminal 4, the positive flight computer input is on the
