STC16F40K128 microcontroller adapter board (convert to DIP40)

This adapter board converts the LQFP-64 packaged STC16F40K128 microcontroller into a DIP40 package and is compatible with the traditional 51 microcontroller development board.

Notice:

1. Except for the UCAP pin, all other pins are lead out.

2. In addition to the 40 pin headers on both sides, there are 7 groups of 22 pins in the middle of the adapter board. You can add it yourself if necessary.

3. STC16F40K128 microcontroller does not support passive crystal oscillator and has canceled the P1.2 pin and changed it to P7.0, P7.1 and P4.7. If you need to use it, just change the pin header to upward welding.

4. STC16F40K128 microcontroller does not support the PSEN, ALE/PROG and EA/Vpp functions of the traditional 51 microcontroller, and has been changed to P7.5, P7.6 and P7.7 pins. If you need to use it, you can change the pin headers of these three pins to be soldered upward.
