Hardware Example 05 — GPS / GNSS

Physically proven full-duplex u-blox NEO-8 GPS/GNSS on ESP32-P4 UART1, exported from ForgeUI Studio and flashed to real hardware.

Purpose and physical proof

The editable ForgeUI Studio Example 05 dashboard used by the standalone export.

Proven wiring and UART

NEO-8 signalESP32-P4 connection
TXIO3 / GPIO3 → UART1 RX
RXIO4 / GPIO4 ← UART1 TX
Serial formatUART1, 9600 baud, 8N1, no flow control

Live NMEA and fix data

  • Checksum-valid live NMEA reception
  • 2D and 3D fix handling
  • 12 satellites observed during physical proof
  • Latitude and longitude
  • Altitude and speed
  • HDOP and UTC

Full-duplex UBX proof

The ESP32-P4 transmitted a UBX-MON-VER request to the NEO-8 and received a checksum-valid UBX response. This proves both directions of the UART1 link; it does not claim persistent UBX configuration.
