+# RFP ESP32-S3 WROOM-1 N16R8 (3 x 106)
+
+This repository includes a tracked PlatformIO target for the RFP ESP32-S3 WROOM-1 N16R8 nodes with three LED outputs and 106 pixels per output.
+
+Build target:
+
+- `rfp_esp32s3_wroom1_n16r8_3x106`
+
+Default output pins:
+
+- Output 1: `GPIO4`
+- Output 2: `GPIO5`
+- Output 3: `GPIO6`
+
+Pins intentionally avoided:
+
+- `GPIO0`, `GPIO3`, `GPIO45`, `GPIO46` for boot / strapping
+- `GPIO19`, `GPIO20` for USB
+- `GPIO33` to `GPIO37` because they are reserved by octal PSRAM / flash on `N16R8`
+- `GPIO48` because it is used as the onboard status pixel
+
+Build:
+
+```powershell
+python -m platformio run -e rfp_esp32s3_wroom1_n16r8_3x106
+```
+
+Build and upload:
+
+```powershell
+.\tools\flash_rfp_s3.ps1 -ComPort COM7
+```
+
+Build only with the helper script:
+
+```powershell
+.\tools\flash_rfp_s3.ps1 -BuildOnly
+```
+
+Local Wi-Fi defaults:
+
+- Keep SSID and password in the ignored file `wled00/my_config.h`.
+- If the file does not exist yet, create it with your local values:
+
+```cpp
+#pragma once
+
+#define CLIENT_SSID "your-ssid"
+#define CLIENT_PASS "your-password"
+```
+
+Important:
+
+- The `3 x 106` bus layout is used as the default when the device has no saved `cfg.json`.
+- If a board already has a saved WLED config, do a factory reset or erase settings once so the default bus layout is recreated.
+
+Onboard status pixel on `GPIO48`:
+
+- `green blinking`: DDP realtime active
+- `green solid`: network connected
+- `blue blinking`: AP / setup mode active
+- `red fast blinking`: Wi-Fi configured but currently disconnected
+- `amber fast blinking`: network connected, MQTT configured, but MQTT not connected
+- `off`: idle / no status to show
