Board Overview

UP100 is a compact LoRaWAN Gateway Module, making it suitable for integration in systems where mass and size constraints are essential. It has been designed with the mini-PCIe form factor, so it can easily become a part of products that comply with the standard, where they allow for cards with a thickness of at least 5.2mm.
The board has two UFL interfaces for the LoRa and GNSS antennas and a standard 52 pin connector (mini-PCIe).

Block Diagram

The UP100 LoRaWAN gateway module is equipped with one SX1303 chip and two SX1250s. The first chip is utilized for the RF signal and the core of the device, while the latter provides the related LoRa modem and processing functionalities. Additional signal conditioning circuitry is implemented for PCI Express Mini Card compliance, and one UFL connectors are available for external antenna integration.

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 register of SX1303 via a synchronous full-duplex protocol. Only the slave side is implemented.
• 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.

Federal Communication Commission Interference Statement

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:

• Reorient or relocate the receiving
• Increase the separation between the equipment and
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
• Consult the dealer or an experienced radio/TV technician for

FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

Radiation Exposure Statement:

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body.

This device is intended only for OEM integrators under the following conditions:

• The antenna must be installed such that 20 cm is maintained between the antenna and users, and
• The transmitter module may not be co-located with any other transmitter or antenna.
• Module approval valid only when the module is installed in the tested host or compatible series of host

As long as 3 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed

IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.

End Product Labeling

This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may be maintained between the antenna and users. The final end product must be labeled in a visible area with the following: “Contains FCC ID:
