+### Serial console
+
+The four-pin through-hole serial header can be seen to the right of the CPU heatsink in the photo above. It is labelled J1, with pin 1 (Indicated by a triangle on the silkscren) at the bottom. the pinout is also on the silkscreen:
+
+| Pin | Label  |
+|-----|--------|
+| 1   | TX     |
+| 2   | RX     |
+| 3   | GND    |
+| 4   | 3V3    |
+
+Adding a header is a few moments work with a soldering iron. Only pins 1-3 are required for serial port use, and the stock firmware outputs at 57600bps at boot.
