TeleMega is a 1¼ inch by 3¼ inch circuit board. It was
designed to easily fit in a 38mm coupler. Like TeleMetrum,
the board is aligned with the flight axis. It can be mounted
either antenna up or down.
+ TeleMega v2.0 has a few minor changes from v1.0:
+
+ * Companion connector matches EasyMega functions
+ * Serial port connector replaced with servo connector with
+ support for up to 4 PWM channels.
+ * Radio switched from cc1120 to cc1200.
+
+ None of these affect operation using the stock firmware, but
+ they do mean that the device needs different firmware to
+ operate correctly, so make sure you load the right firmware
+ when reflashing the device.

=== TeleMega Screw Terminals
TeleMega has two sets of nine screw terminals on the end of
the board opposite the telemetry antenna. They are as follows:

TeleMega 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.
