EasyMega is a 1¼ inch by 2¼ inch circuit board. It was
designed to easily fit in a 38mm coupler. Like TeleMetrum,
EasyMega has two sets of nine screw terminals on the end of
the board opposite the telemetry antenna. They are as follows:

=== Using a Separate Pyro Battery with EasyMega
EasyMega provides explicit support for an external pyro
battery. All that is required is to remove the jumper
between the lipo terminal (Bottom 3) and the pyro terminal
- (Bottom 2). Then hook the negative pyro battery terminal to ground
- (Bottom 1) and the positive pyro battery to the pyro battery
- input (Bottom 2). You can then use the existing pyro screw
+ (Bottom 2). Then hook the negative pyro battery terminal to
+ ground (Bottom 1) and the switched positive pyro battery to
+ the pyro battery input (Bottom 2). Note that you must include
+ a switch between the pyro battery and the board for safety,
+ as the on-board power switch circuit only supports the primary
+ battery! You can then use the existing pyro screw
terminals to hook up all of the pyro charges.
