Design a single-sided, through-hole control PCB. Logic is 3.3V. One copper layer (bottom), wide tracks (1.5–2mm), add a GND copper pour, screw terminals for every external connection. Use this exact netlist (authoritative).
PARTS
  • U1: ESP32 DevKit 38-pin module on two 1x19 female headers (2.54mm pitch socket). USB toward board edge.
  • R1, R2: 10k. R3, R4: 10k. R5, R6, R7: 220 ohm. (all THT axial)
  • C1: 100nF (THT).
  • J1: screw terminal 2 pin. J2: 3 pin. J3: 3 pin. J4: 4 pin (5.08mm pitch).
NETS
  • +5V: J1.1, U1.VIN, J2.1
  • GND: J1.2, U1.GND, J2.3, J3.3, C1.2, R2.2, R3.2, R4.2
  • +3V3: U1.3V3, J4.1
  • VOUT_SENS: J2.2, R1.1
  • ADC34: R1.2, R2.1, C1.1, U1.GPIO34
  • PUMP: U1.GPIO25, R3.1, J3.1
  • VALVE: U1.GPIO26, R4.1, J3.2
  • LED_R: U1.GPIO27, R5.1
  • J4_R: R5.2, J4.2
  • LED_B: U1.GPIO14, R6.1
  • J4_B: R6.2, J4.3
  • LED_G: U1.GPIO13, R7.1
  • J4_G: R7.2, J4.4
PLACEMENT
  • U1 centered, screw terminals along the edges: J2 and J1 on the right, J3 and J4 on the left.
  • Then route everything on the bottom layer with wide tracks and add the GND pour.

I’m blocked from making project changes because this account currently has no available ACUs, so AI execution features are unavailable right now.
Nothing has been added to the project yet; it is still an empty draft with 0 components and 0 nets. Remaining work is to create the schematic from your authoritative netlist, add the ESP32 DevKit socket headers, THT passives and screw terminals, then place and route a single-bottom-layer PCB with 1.5–2 mm tracks and a GND copper pour.
Once ACUs are available, the next steps are:
  • Add all specified through-hole parts and exact nets.
  • Set the project name/description to match this control PCB.
  • Place U1 centered, terminals on left/right edges as requested.
  • Configure one copper layer / bottom routing intent, wide tracks, and GND pour.
  • Run ERC/DRC and verify no missing nets or airwires.
