I think the schematic looks good, however before I order PCB's based on this, I would request a review of the logic by experts.
- I want to use GPB0-7 as GPIO INPUT mode, therefore using 10K pull down resistor.
- MCP23017 reset pin is connected to VCC.
- MCP23017 INTA, INTB pins are left unconnected.
- DHT11 data pin is connected to VCC via 5K.
- General observations if any.
Thank you for your valuable time to go through and giving your feedback. Thanks a ton. :)
