atmega8-328 prototype board: good voltage filtering function

This board was created for the mcudude library and has good voltage filtering, reducing reset time via a c10 capacitor (10nF!!) on the dtr line of a ch340 system. It would be nice to solder a precision socket under the x1 oscillator, it gives you the opportunity to try different frequencies (useful for rs232 communication for example)​
