increase in GPIO pins

I wish to use 30 GPIO pins for my DIY project. But board provides only 19. Is there any way i can increase the no og GPIO pins on the board. Or could convert other non GPIO pins to GPIO pins??


I count over 50 GPIO pins. You might have to reconfigure some of them.
What are you trying to do? Is it also going to have an LCD display hooked to it?
Another alternative is to use I2C Expanders like PCA9555, if the I2C bus is fast enough for your project.
