+In some sticks, such as those based on lantiq, the serial is exposed in the upper pins of the ONT, in order to read them there are 2 possibilities:
+- the use of an SFP molex ([farnell](https://it.farnell.com/en-IT/molex/74441-0001/connector-sfp-rcpt-20pos-smt/dp/2112385)) to which you solder 4 wires and remove the other pins, this makes the adapter compatible for a single serial combination
+- the use of a board to which the SFP molex is soldered, exposing the main SFP pins

+- 2x pinout 2x10 (like [MINTRON MTP125-1210S1](https://www.lcsc.com/product-detail/Pin-Header-Female-Header_MINTRON-MTP125-1210S1_C358699.html))

+
+A TTL UART adapter makes it possible to connect the stick's serial to a computer via a USB interface, and on the computer through serial emulation it is possible to send commands just like the serial ports of the 1990s
+
+Is widely used in the modding of SFPs, and in general of most embedded devices, since a serial port is always present in all of them and is also used to de-briking the devices.
+
+TTL adapters are widely found on amazon, the most recommended one being:
+
+- DSD TECH USB to TTL Serial Adapter with FTDI FT232RL Chip [Amazon.com](https://www.amazon.com/dp/B07BBPX8B8) [Amazon.it](https://www.amazon.it/dp/B07BBPX8B8)
+
+Alternatively, an [Arduino can be used to emulate a TTL adapter](https://create.arduino.cc/projecthub/PatelDarshil/ways-to-use-arduino-as-usb-to-ttl-converter-475533)
