 The DFPlayer module can be powered by 3.3v to 5v, with 4.2v recommended.  A fully charged 1S, 3.6v lipo provides adequate voltage.  At full volume the board may use 70ma+ momentarily, and in standby it is rated at 20ma.  In testing, a 200mah 3.6 lipo lasted over two weeks of regular use (15-20 min/day).
 Although not required, the Pololu S7V8A adjustable stepup/stepdown regulator can ensure that the voltage is consistent and stable.  It can be wired to a 3.3 or 5v switched source near the power circuits (the location of which will vary by TX) to avoid affecting other electrical needs of the transmitter.  The S7V8A can also be wired directly to the battery-in port, provided that the -SHUTDOWN is connected (varies by TX).
 Here are some example power locations for transmitters. The forums may provide additional information as more pilots adopt the voice alerts feature.

   *   In the Devo 7e power is a challenge: search the forum for more details.  [[https://www.deviationtx.com/forum/6-general-discussions/6246-devo-7e-voltage-supply?start=20#53017|This excellent post]] is a good place to start.
+==== Jumper T8SG V2 ====
+The Jumper T8SG V2 and T8SG V2 plus are already prepared for installation of a DFplayer module.
+The picture shows the necessary parts to get started. Basically any speaker with 22 mm diameter works fine.
+{{ :hardware:voice:voice-mod-parts-01.jpg?600 |}}
+First, you need to remove 2 pins on the left and 6 pins on the right side of the DFplayer module as depicted below.
+{{ :hardware:voice:mp3-dfplayer-mini-01.jpg?600 |}}
+Now you can solder module to the T8SG V2 PCB. You will have to unmount the main PCB to solder the pins on the bottom side.{{ :hardware:voice:dfplayer-min-01.jpg?600 |}}
+The speaker can be mounted beneath the RF module at the top of the case and wired to the adjacent free header with a PH1.25 mm connector or directly wired to pins on the DFplayer module.
+{{ :hardware:voice:speaker-22x3.jpg?600 |}}
+To fit the battery compartment, you will have to cut along the prepared lines with a sharp knife or a small saw to make room for the DFplayer before reassembling the transmitter.
+{{ :hardware:voice:battery-comp-01.jpg?600 |}}
+Follow the software instructions below and setup hardware.ini for DFplayer and UART5 usage:
+<code ini>
+voice=dfplayer
+voice-uart5=1
