[Product] M5StamPLC: ideas for next version

felmue

Hello guys

some ideas for the next version of M5StamPLC:

switchable 5 V on Grove ports
switchable 5 V on extension port
LED indicators for the relays
LED indicators for the inputs

Notes for 1.: the existing ICs can be used by connecting output (P3) of (U5 PI4IOE5V6408) to the enable (EN) of (U4 LPW5209AB5F) instead of having EN tied to SYS_5V.

Notes for 2.: the existing ICs can be used by connecting output (P1_0) of (U4 AW9523B) to the enable (EN) of (U8 LPW5209AB5F) instead of having EN tied to PMU_5V.

Thanks
Felix

LEDs for IOs are standard on any PLC device. Display is good, but a simple led is better as it always works regardless of a software.
