Analog of USB Elinv Prog programmer device (connection via USB port), performed on FT232RL chip.
This device successfully replaces the USB Elinv Prog, although the design is simpler and much less expensive.
If the drivers are installed correctly (see USB Elinv Prog section), the device will be determined by the Sky Prog Programmer software as the USB Elinv Prog device.
You can buy, for example, on aliexpress.com. The price is very low, 3-4 $.
The figure below shows which device points are needed for the connection to the PCB.
Power can be used 5 volts or 3.3 volts.
Attention please! For work you need connect together the CTS and DTR pins. It is the SDA line.
Also do not forget for an Indesit arcadia PCB the power supply must be 5 Volt, and for Candy only 3.3 Volt.
There are other options on the FT232RL chip, there are a lot of them on the Chinese website aliexpress. Almost all of them are suitable for programming modules using the software Sky Prog Programmer. You need to find the right points for connection and make wires from them to the module.
Below is a concrete example of the development of the device for Sky Prog Programmer sofware.
1. Modification on the upper side of the board:
2. Modification on the back of the board:
3. Assemble the adapter and connect the FT232RL device to the module like this:
With this connection to the ARCADIA PCB, set the jumper to 5 volts.
