+- P - OUT - Pulse, 1Hz, 100ms length, rising edge
+- M - IN  - Mode select
+- D - UNK - Unknown
+- R - IN  - UART RX receive
+- T - OUT - UART TX transmit, 115200baud, 8 data bits, no parity, 1 stop bit
+- G - N/A - Ground
+- V - N/A - VCC, maybe 5V, but 3V3 are working properly

+The boards needs a separate UART chip for easy use. The module can be reconfigured, like baudrate, NMEA messages, etc. The pcb is prepared to have a onboard antenna or otherwise a IPEX connected external one. The switch is done by a soldered 0Ohm bridge (bright green).
+Two LEDs showing power (red light, full red) and PPS (green light, orange). To buffer the internal RTC a "thing" is soldered (bright red) [ToDo]
+Maybe a power LDO is mounted. (purple)
+Maybe a flashing header is onboard, bit covered in solder (yellow)
