Sensor Wiring Setup
GND_24V and GND_LOGIC.+24V_SENSOR / GND_24V.LIMIT_X_NET connects to Nano D9; LIMIT_Y_NET connects to Nano D10.HX711_CONN because U5 (HX711) is onboard.SD_CONN header with MICROSD_SOCKET (ST-TF-003A) as an onboard microSD socket.MICROSD_SOCKET to ESP32 SPI:
CS → SD_CS / ESP32 GPIO10SCK → SD_SCK / ESP32 GPIO12DO → SD_MISO / ESP32 GPIO13DI → SD_MOSI / ESP32 GPIO11VCC → +3V3GNDRELAY_OUTPUT_CONN (Phoenix Contact 1987737) as a 3-position terminal block:
RELAY_NORELAY_COMRELAY_NCY_SENSOR_CONN exists in schematic and has a PCB footprint.ESP32 is at a board edge with USB/antenna access intent preserved.NANO is at a board edge for USB access.MICROSD_SOCKET is placed near ESP32.Completed
