+# IG108
+
+Following is documentation for unmanaged switch marked as `IG108`.
+
+Original software is running UART on 9600 baud rate.
+
+Using SPI clamp in-board is the only method for initial installation.

+- **Settings**: 115200 baud / 8N1 / 3.3V TTL
+
+### Power supply
+
+Input power is delivered via barell plug, `12V 1A` adapter was provided.
