Hi @rambinator, Yeah, I missed the 2x, very sorry.
Let's try again. I've got some kit, so I'm going to try and see where it takes us.
Home > Store > Sensors > Hat(s) > ENV III – the picture gives G0 I2C-SDA, G26 I2C-SCL
I have the ENV III unit, not hat, so I used a Groove2Dupoint and made the connections to I2C on the unit (plus 5V and GND). In UIFlow, I added the unit on custom pins 0 and 26 and made the simplest temp label 1 sec loop. Run and temp reading appeared, nice.
Next I have the PaHUB (I2C-to-I2C), so I added the hub with custom G0 I2C-SDA, G26 I2C-SCL and ENV III to PaHUB|#0
Run and "Pahub unit maybe not connect", not shocked – read my other posts.
Switch PaHub from custom GPIO to Port A (bottom), Run and ta-da temp reading ok on screen via the hub. And that's my concern for you with the PbHUB option (my issue might just be because I2C devices/PaHub). Now, the hub is quite cheap, so you could try it, maybe use Port A and put the 8-encoder on the top (custom pins 0 and 26).
There are 3 pins at the top (0, 26, 36), which I would have said should suffice for proto hat option. However, I don't think all the PIN ports at the top are the same. I'm speculating here – @felmue help please – but I think the following for I2C.
G0 - Fine SDA/SCL
G26 - Fine SDA/SCL
G36 - Couldn't find the unit because it's ADC, but it might be fine for the limit switch, risk with the angle units.
In conclusion, I'd go for the PbHUB try it through the hat connection G0, G26, and connect angle units (GPIO) and limit switch (GPIO) to it. Use the bottom Port A for the 8-encoder. If you get error messages about the hub, swap top to bottom (fingers crossed).
PS You might want the proto hat as well. The Dupont to top of StickC next to each other are a little tight. Might also save you the buy of Groove2Duponts because you will get one cable with each device (cut one in two to give bare cable to Groove).
