We are refining equipment Turnigy 9x
Everyone who is interested in radio-controlled models is known for the Turnigy 9x hardware. This is almost a folk equipment RU.
Affordable, there are many accessories and alternative firmware for it. For example, my copy looks like this:
It has an alternative firmware - er9x, the screen backlight has been added, the sticks have been replaced with wide ones, a folding stand has been added to the back, a cable has been inserted in the battery compartment for flashing and editing settings from a PC, powered by a 2S LiIon battery.
And everything is good in this equipment, because it is modular. You can put any transmitter module JR standard. And there is a sea of them - for almost every wallet and task. However, there are two options for configuration - with a native radio module Turnigy 9x and generally without a module.
The native module does not have its own antenna and is connected to the upper antenna on the transmitter body by a one-piece cable so that the module cannot be disconnected and it can only be replaced by biting the antenna cable:
Separately, the native transmitter module is not for sale, because version of the equipment without a module also without an antenna:
So to put it in the version without a module in the kit will not succeed. There are alterations in the network, where the antenna is placed on the back wall of the module, but using the transmitter in this version is terribly inconvenient - you can’t put it on the table, you can’t put it in the backpack without the risk of breaking the antenna:
But the native module is good - it is compatible with a whole bunch of inexpensive receivers for 4, 6, 8 channels, and also compatible with micro helicopters:
In general, I do not want to abandon it. Well, we will not. Let's make this module fully replaceable.
We take out the module from the socket, unscrew the two screws and remove the back cover. Do not break the antenna cable!
Inside a sandwich of two boards, fixed with two snot glue. Carefully remove the hot melt glue and unsolder the antenna. It is necessary to solder quickly - lead-free solder, it is necessary to heat strongly, and the tracks are thin. Now you can shake out the electronics on the table.
Now we take a copper sheath (desoldering wick) and richly soak it with a flux, carefully remove the solder from the comb connecting the boards. Disconnecting boards:
By the way, it is clearly seen that the module produces FlySky, from which Turnigy9x is copied :)
The large module contains a button binding and a linear stabilizer on the back side. We will leave it in the box, and we will move the transmitter itself inside the equipment case, the benefit of the place is full there. There are many pins on the module, but we need only 4 of them: power, ground, PPM signal and a button.
To do this, disassemble the equipment case by unscrewing all the screws in a circle and carefully disconnect the wiring harness connecting the case halves.
On the back half, fasten the transmitter board with a double-sided porous adhesive tape and solder the antenna cable in place. And we drill three holes in the board and align the edges with the PBS-4 connector with the file:
On the back of the hole looks like this:
Then we insert an empty module case and mark the hole on the inside with a marker, then remove the case and cut out the response hole in it:
Now we insert the PBS-4 connector into the hole so that it is flush with the bottom of the niche from the back:
Fix it with superglue and, after drying, you can add hot melt to strength.
Connecting wiring connect the connector and module:
Now we insert the empty case again and insert the plug PLS-4 into the already glued-in connector through the hole, carefully fasten the plug in the module case with superglue, wait until it dries out and fix the result with hot glue. We solder the wiring to the board and fasten it with the same hot-melt adhesive, as was done by the Chinese.
We close and screw the lid, assemble the equipment case.
Voila, we have a native module that can be removed and put in place of any other one. The quality of communication does not suffer at the same time - the entire HF part is inside, and through the connector we drive only the PPM and the power of the radio module.
That is, for the same money we get a full-fledged modular equipment.
