2 Device description
2.1 USB
A USB 2.0-compatible serial port is featured for data communication and power supply. USB drivers
are installed automatically through Windows update.
2.2 UART
The unit includes an RS-232 port which can be dynamically connected to the UARTs of the ZED-F9R
module or the MCU. Selection of the UART connection is controlled by the NEO_UART_SEL and
MCU_UART _SEL pins on the front connector.
NEO_UART_SEL MCU_UART_SEL Connected component
LOW OPEN Reserved
OPEN LOW MCU
OPEN OPEN ZED-F9R
LOW LOW None
The selected UART interface is also available via the RxD and TxD pins on the front connector.
☞
RxD and TxD pins on the front connector are at TTL voltage levels.
⚠
Flow control should not be used with the RS-232 port.
2.3 Antenna
The kit includes u-blox ANN-MB L1/L2 active multi-band GNSS antenna with a 5-meter cable. There
is a female SMA connector (RF IN) available on the front side of the unit for connecting the antenna.
⚠
Do not use the SMA connector in the back. It is reserved for future use.
2.4 14-pin front connector
