RC2024 – Part 14 – New Rotary Encoder PCBs

Rotary Encoder Modules v1.2 and v1.3 for the RC2014

Last week I wrote about refining my Rotary Encoder Module for the RC2014. The updated PCBs have arrived so I have soldered them up.

There are two versions, one that allows any address between 0 and FF to be selected. The other uses only address D7 or A7. These are the addresses that Spencer has reserved for Rotary Encoders on the RC2014.

Apart from the addressing, the main changes were to add pull up resistors to the input pins. This means when a rotary isn’t attached, they are held high. This matches the behaviour when a rotary encoder is attached. To save space on the PCB, I swapped from using separate resistors to using resistor arrays.

They work perfectly.

I do like the look of the two new boards. They look like a real product.
