A SFP to TTL adapter board (Maobang brushing board)

Overview

A simple SFP to TTL adapter board for flashing.
Recently, I was playing around with all in one small consoles and wanted to try to get rid of the operator's optical modem to break the upper limit of network speed. I found such a small thing after checking the relevant information. The price of flashed cat sticks in the seafood market is generally upwards of 100 yuan. In order to save money, the garbage guy bought unbrushed cat sticks and tried to flash the machine himself, so this adapter board came into being.
A very simple gadget with no technical content.

PS: After verifying the first version of the board, it was found that there was a problem with the soldering pad of the SFP interface. The second version has been corrected, so you can build the board with confidence. Use 20P dual-row SFP interface, please pay attention when purchasing.
