I used STM32F107+DP89848+OCM2521 to build a fiber optic Ethernet. OCM2521 is a 100M multimode fiber optic module with a voltage level of 3.3v (LVPECL), but it didn't work. The loopback test was succes...
This is my first time making an STM32 board, model F103ZET6. After the PCB arrived, I soldered the STM32 to the board. Because the DCDC chip had not arrived yet, I brought out the SWD interface, used ...
Transistor amplifier circuit: The input voltage range is wide, and the parameters of each component are based on actual experimental tests and have been adjusted to a suitable static operating point. ...
