[Solved] Replacing Damaged Toy Car Remote Control Module: Swap & Wiring Guide (New vs. Old)

Hello

I would like to repair the toy car with a battery - damaged remote control module (I can't get this module anywhere). The site recommended a similar one that is easy to modify . The problem is I can't do it. If someone could advise:

1. Is it possible to swap these modules at all?

If so, then I would be very grateful for drawing a simple diagram (for beginners). How to swap cables so that you don't burn anything.




The first in the photo is the new module, the second is damaged.

You probably have to exchange

And the module is available on AliExpress - https://www.aliexpress.com/item/27-145mhz-ele...ar-aircraft-shape-remote-control-Children-toy /32803573692.html?spm=2114.010208.3.1.7GA4mH&ws_ab_test=searchweb0_0,searchweb201602_3_10152_10065_10151_10068_436_10136_10137_10157_10060_10138_10155_10062_10156_10154_10056_10055_10054_10059_100031_10099_10103_10102_10096_10147_10052_10053_10107_10050_10142_10051_10171_10084_10083_10080_10082_10081_10110_10111_10112_10113_10114_10181_10037_10183_10182_10185_10032_10078_10079_10077_10073_10070_10123,searchweb201603_16,ppcSwitch_5&btsid=6a04c5c5-1aa6-4719-a3fd-55ac71a98071&algo_expid=285e30f2-da78-42e1-86dd-fe0ff4d90c62-0&algo_pvid=285e30f2-da78-42e1-86dd -fe0ff4d90c62

Thank you for the quick reply. The problem is that the first module in the photo is a new one I bought in the hope that I will be able to convert it so that it replaces the second one in the photo.
For lack of patience - I ordered the speed controller - I connected and works (toy car for a 4-year-old also operation with a remote control is not necessary)
However, there remains the problem of changing the direction of rotation of the engine.

If there is no remote control, then the young one in the original also had to have the option of forward-backward driving. There is probably a pickup or reverse switch on the board - without playing the H bridges, connect the motor to the controller via a relay with two sets of switching contacts changing the polarity of its connection switched from this switch (or use two or four unit relays dismantled from the damaged controller - only these efficient).

I think it is enough to install the switch to stop, start - forward and backward

For example or similar

Finally, I put in the module and all the original wiring. I ordered a speed controller with the function of changing the direction of rotation. I put two 12v batteries connected in series to get power reserve. Nominal 12v engines were very hot - I put in two windmills and the problem was limited. When one of the engines refused to obey (about 50 hours of fun). I decided to order two gears with 2 x 24v 12000 engines. A typical off-road transmission also develops at 36v to 8.6 km / h.
I will add that every few hours of driving thoroughly lubricates gears with gear grease, thanks to which they work quietly and almost without signs of wear. It is worse with the culture of engine operation. If anyone could advise a model working at voltage up to 36v and min. 12,000 boron. I will be the leader.
