If pins 22 through 29 are not used for anything else, soldering jumper wires onto a spacer or directly onto the PCB might be an option. Otherwise, as @Jot suggested, software PWM is always an option, but they achievable frequency would be limited. | |

| Mar 25, 2019 at 12:46 | comment | added | Jot | It is not possible to route pins to other pins, the functionality of a pin is fixed to that pin. You could try a software pwm library. | |
| Mar 25, 2019 at 12:40 | comment | added | DrBwts | I want to generate the PWM on pins {2, 3, 4, 5, 6, 7, 8, 9} using analogWrite() but replicate that output on pins {22, 23, 24, 25, 26, 27, 28, 29} | |
| Mar 25, 2019 at 12:33 | comment | added | chrisl | It is not clear, what you are trying to achieve. What I understood is: You want do measure the value of the PWM signal on the pins {22, 23, 24, 25, 26, 27, 28, 29} and then outputting a new PWM signal with the same value on the pins {2, 3, 4, 5, 6, 7, 8, 9}. Is that correct? | |
