These are KiCad files and you are free to do what you will with them. KiCad is a good, free, and fairly

easy to learn. Build your own BOM and gerber files.

This is a variant of the Multipro V2.3c circuit design. It is basicly the same as the 2.3c board as far
|
|
as component placement goes. What's changed is the added resistors for the serial protocol and also
|
|
the addition of solder jumpers on the bottom of the board for the various options to connect the TX, RX, and PPM
|
|
lines through them. See below for more detail.
|
|
|
|
The schematic has been updated to reflect the added components and jumper pads as well as cleaned
|
|
up a little. As it sits now, the .net file loads without any complaints and DRC checks pass.
|
|
|
|
The jumpers, and how they are used:
|
|
|
|
|
|
There are four solder type jumpers on the bottom side of the board near the lower left corner when the
|
|
bottom of the board is facing towards you. The silkscreen shows which jumper is which. These four jumpers
|
|
enable the board to be configured in several ways as explaned below.
|
|
|
|
(J-1) Use (PPM V/V) if the incoming PPM signal is at a higher voltage level, leave open if ~~5V.
|
|
|
|
(J-2) Use (Jumper 2) to connect the incomming PPM signal to the RX pin on the processor
|
|
|
|
(J-3) Short (TELEM) only if you have done a telemetry mod to your radio, leave open if not needed. When
|
|
connected, pin 2 of the two pin header (P3) is also connected.
|
|
|
|
(J-4) Use (MOD) only to connect the transmitter pin 2 to pin 1 of the two pin header (P3).
|
|
|
|
The direction this project is going, it is most likely J-2 will be the only one needing to be shorted for
|
|
the serial method of sending model protocols.
