I have to solder a microcontroller that belongs to an Arduino Uno to a PCB. The Arduino uno uses the Atmega328p which has 28 pins. On the pcb I have, i see only 27 pins for the microcontroller.

Could i still somehow be able to place the 28 pin microcontroller on this PCB? Or should i make a new PCB with the 28 pins for the microcontroller?

Thanks!

P.S I dont need all the 28 pins for the project.

Doing some research i found this footprint package: https://easyeda.com/component/ATMEGA328P_PDIP_EZ-BbicICwO6

I also never knew a 27 pin microcontroller existed or the footprint at least..

Thanks!
