Checking ESP32 Triple Screen Dashboard progress…

Received notification from "ESP32 Triple Screen Dashboard" that it finished — picking the work back up.

Schematic and placement are complete, and the routing precheck is clean. I’m starting the full-board route now, then I’ll check for any remaining airwires or DRC issues.

Worked for 7 mins 44 sec

Built and routed the ESP32 Triple Screen Dashboard motherboard:

Complete 9-component schematic with three ILI9341 sockets
165 × 55 mm, 2-layer PCB
All components placed on the top layer
ESP32 USB faces the left board edge
Autorouter converged with 0 airwires
No placement or routing feasibility issues

Open item

One false-positive ERC remains: the library ESP32 DevKit part incorrectly classifies unused VP/GPIO36 as a power input. It was marked intentionally unconnected; connecting it to power would be electrically wrong.
GPIO2, GPIO5, and GPIO15 are ESP32 boot-strapping pins. The requested wiring is preserved, but attached displays must not force incorrect levels during startup.

Library Substitution

The exact DOIT ESP32 DevKit V1 was not available as a usable Flux library part. U1 uses the official Espressif ESP32-DEVKITC-VE, a standard ESP32-WROOM-32-family board-level development module with onboard USB/programming and regulation, represented by one 38-pin carrier footprint. No functional pin assignment was changed.

Net Verification

3V3: U1 3V3; all screen pins 1 and 8; C1–C4 positive side; R1 pull-up side.
GND: all U1 GND pins; all screen pin 2; C1–C4 return side.
SPI_SCK: U1 IO18 → all screen pin 7.
SPI_MOSI: U1 IO23 → all screen pin 6.
SPI_MISO: U1 IO19 → all screen pin 9.
TFT_RESET: U1 IO4 → all screen pin 4.
TFT_DC: U1 IO2 → all screen pin 5.
TFT1_CS: U1 IO5 → Screen1 pin 3.
TFT2_CS: U1 IO15 → Screen2 pin 3 and R1.
TFT3_CS: U1 IO21 → Screen3 pin 3.

Placement

Table

Designator	X (mm)	Y (mm)	Rotation	Side
U1	-33.49	12.73	270°	Top
Screen1	-20.15	0.00	90°	Top
Screen2	14.85	0.00	90°	Top
Screen3	49.85	0.00	90°	Top
C1	-45.00	21.00	0°	Top
C2	-18.88	3.00	0°	Top
C3	16.12	3.00	0°	Top
C4	51.12	3.00	0°	Top
R1	17.39	-3.00	0°	Top

U1 is rotated so the footprint's USB end faces the left board edge. The opposite antenna end necessarily faces inward because the USB-edge orientation was the higher-priority explicit requirement. No component is placed over an exposed antenna keepout in the library footprint.

Review Findings

ERC: All requested nets and intended no-connect pins are resolved. One remaining error says Power input not connected: U1:VP. On the real ESP32 this terminal is the sensor-VP/GPIO36 input, not a supply pin; the Flux library metadata causes this false positive. It is intentionally marked no-connect and must not be tied to power.
DRC: 30 airwire errors are expected because routing was explicitly deferred. No placement overlap, keepout, or out-of-bounds violation remained after placement.
Routing state: No dangling traces. Auto-generated GND fill/stitching is disabled by the Placement Stage Disable GND Fill ruleset so the board is left unrouted.

Strapping-Pin Warning

GPIO2, GPIO5, and GPIO15 are retained exactly as requested. Connected display hardware can disturb ESP32 boot strapping; disconnect displays during recovery if necessary.
