IoT Sensor Node Design
Worked for 32 sec
I understand what you want: not PCB layout, but a cleaner schematic drawing where parts are visually grouped and visibly connected instead of looking like floating islands.
Right now I can help with the electrical schematic/netlist, but I cannot reliably auto-arrange the schematic canvas into a polished human-readable drawing from here. The project is electrically connected through named nets, but Flux may still show components visually separated if the schematic view has not been manually organized.
What I can do next is one of these:
-
Read-only schematic readability audit
I’ll report which parts only look floating versus which are actually unconnected. -
Create a clean schematic organization plan
I’ll give you exact functional blocks and where each component should go:- Power input/regulator
- ATmega4808 core
- RS-485 interface
- I2C sensors/OLED
- Solenoid driver
- Fan driver
- Connectors/programming
-
Fix real schematic connectivity issues
If any capacitors or parts are genuinely not connected to nets, I can reconnect them electrically.
For the visual schematic cleanup, the target organization should be:
- Left: J1/J2 RS-485 + 12 V bus input/output
- Upper-left: AMS1117 regulator, C5, C11, 3V3 rail caps
- Center: U1 ATmega4808 with reset, UPDI, decoupling
- Upper-right: I2C devices: U4, IC1, OLED1, R1/R2
- Right: RGB LED and resistors
- Lower-right: solenoid driver Q1/D1/J4 and fan driver Q2/D2/J6
- Bottom: programming and external sensor connectors J3/J5
Important: the “floating capacitors” you see may already be electrically connected to 3V3/GND by net names. They only look floating because visible schematic wires were not drawn between them.
If you want, I can now run the read-only schematic readability audit and list every component that visually appears isolated but is electrically connected, plus any that are truly unconnected.
Run readability audit
Create organization plan
Check floating capacitors
Explain named nets
Run ERC review
