| Comparing an Alps rotary encoder to chinese rip-off |
| << < (4/8) > >> |
| Jan Audio:
I buy the cheap one and replace with good one later. Not going to pay price high as the alps for test projects. Thnx for the 10K advice, i just use 100n, next project i try 10K. |

Have you seen the PEC11 Series suggested filter? |
| Jan Audio:
Are those extra resistors worth the space ? That is 4 per encoder, gonna try 2 first. Oh wait those are pullup-resistors, and i have those internal in the PIC, hmz. So you need pullups disabled in the MCU for this one. |
| exe:
I had the same dilemma, and I ended up with just using cheap encoders. Motivation: it works fine, usability is not affected by this. I don't know how long they will last, will see. |
