Increase i/o in industruino

Hi! I have bought an industruino ind i/o, but i need to more digital input/outputs. I've noticed that is an expander to give the gpio. I need to know if there are some pin free out of the 16bit pcal9555a used in the digital i/o section. Else, i think that i can use a second pcal9555a with different spi address. Would be nice to do a little board to put inside the case with same protections that are aready onboard and replicate them.

This would be the best way to have more i/o?

Thanks!

If you only need some more Digital Inputs and you are using only dry contacts, you could multiplex your dry-contact DIs on one AI. We are doing this and manage to cram 5 Dis on one AI.

Ask me directly if interrested in a sketch of the thing with its code.

Hi! I'm doing a little board based in the components used in the ind i/o to add or 8in + 8 out or directly 16 bidiretional io, talking via i2c. I've noticed also some interesting rs485 i/o modules...

Hi, to achieve more I/O channels we recommend connecting 2 INDIO units by Modbus RTU (using the including RS485) as described here https://industruino.com/blog/our-news-1/post/modbus-rtu-master-and-slave-14

We have a product in the pipeline which has the double of the current channels plus extra features, stay tuned
