Hardware

The hardware is categorized into several parts. It discusses the interfacing, pinouts, and its

corresponding functions and diagrams. It also covers the parameters and standard values of the

board.

Interfaces

 SPI Interface – SPI interface mainly provides for the HOST_SCK, HOST_MISO, HOST_MOSI,

HOST_CSN pins of the system connector. The SPI interface gives access to the configuration

 USB Interface – The USB interface mainly provides for the USB_D+, USB_D- pins of the system

connector. The USB interface gives the access the configuration register of SX1303 via an

MCU STM32L412. Only the slave side is implemented.

 UART and I2C interface – UP100 integrates a ZOE-M8Q GPS module which has UART and I2C

interface. The PINs on the golden finger provide a UART connection and an I2C connection,

which allows direct access to the GPS module. The PPS signal is not only connected to SX1303

internally but also connected to the golden finger which can be used by the host board.

 GPS_PPS – UP100 includes the PPS input for received packets time-stamped and Fine

Timestamp.

 RESET – UP100 SPI card includes the RESET active-high input signal to reset the radio

operations as specified by the SX1303 Specification. UP100 USB card’s RESET is controlled by

MCU.

 Antenna RF Interface – The module have one RF interface over a standard UFL connector

with a characteristic impedance of 50Ω. The RF port supports both Tx and Rx, providing the

antenna interface.
