 1. **GNSS Flex Male Headers**
 :	The *carrier* boards host GNSS Flex modules on the two 2x10-pin, 2mm pitch male headers. A standardized pin layout, keeps the ecosystem pin-compatible for upgrades and allows board to be easily swapped for repairs. Depending on the capabilities of the GNSS receiver, these pins will breakout the USB, UART (x4), I<sup>2</sup>C, and SD card interfaces along with any PPS or event signals of the GNSS receiver.
 1. **Status LED**
-:	Often *carrier* board will include status LEDs to indicate the board is powered, the RTK status, a PPS signal, and a GNSS fix.
