2023/9/22 14:58 Monitor One Datasheet | Reference | Particle Monitor One datasheet The pictures in this preliminary datasheet are of a pre-release unit. The production units will be a dierent color, and may have other minor dierences. The Monitor One is an o-the-shelf complete gateway design, like the Tracker One. The Monitor One is in a larger IP67 waterproof enclosure with room inside for an expansion card and additional connectors, allowing it to be used in more custom scenarios than the Tracker One. Ready to go with rugged IP67-rated enclosure with room inside for an expansion card. https://docs.particle.io/reference/datasheets/tracker/monitor-one-datasheet/

6/56 2023/9/22 14:58 Monitor One Datasheet | Reference | Particle By default the Monitor One uses the internal cellular and GNSS antennas, but can be switched to using the external connectors inside the enclosure. The cellular (1) and GNSS (4) antennas are not connected internally at the factory. In order to use the external connectors you must open the case, disconnect the internal antenna, and instead connect the U.FL connector for the external jack. The Monitor One is equipped with 2 external-facing SMA bulkhead connectors for both cellular and GNSS but are disconnected internally. The hardware is ready for use with external antennas giving the ability to connect a wide variety of application-speciic antennas. It is recommended that the user perform required RF certiications with the selected antenna installed as the Monitor One has only been certiied for use in select regions with the internal antennas. Mounting The Monitor One is intended to be mounted in the orientation shown at the top of the page, with the connectors facing down. You can also mount it with the mounting plate mounted on a lat surface as the GNSS antenna is angled to allow it to work in either orientation. When using external cellular and GNSS antennas you can orient the Monitor One in other directions. https://docs.particle.io/reference/datasheets/tracker/monitor-one-datasheet/

GPIO and port leakage current warning Be careful when you are connecting GPIO or ports such as serial that may have power when the Monitor One is not powered, such as when using shipping mode. If you have current lowing into GPIO or ports of the nRF52840 when it is powered down, it can cause it to enter a state where it cannot be reawaked without removing all power from it, including the internal LiPo battery. This may be diicult if you've sealed your Monitor One enclosure. https://docs.particle.io/reference/datasheets/tracker/monitor-one-datasheet/
42/56 2023/9/22 14:58 Monitor One Datasheet | Reference | Particle The Tracker One has a TI TS3A5018 Quad SPDT Analog Switch on the three GPIO pins (A3, D9/RX/SDA, D8/TX/SCL) to prevent this. The switch is normally open, and is closed when the CAN_5V is powered. By default, Tracker Edge enables CAN_5V when in normal operating mode and turns it o during sleep, however this behavior can be changed by using enableIoCanPower() and enableIoCanPowerSleep() in the TrackerConfiguration object. The Tracker One circuit looks like this, and you may want to implement something similar if you are in a scenario where you have externally powered peripherals. This is not necessary if your external peripherals are powered by 3V3 or CAN_5V. VIN disable By default, if power is applied at the VIN pin it will be used to power the Monitor One and charge the built-in battery. If you are supplying VIN from another, larger battery pack, and want to be able to disconnect the VIN power supply to minimize current loss, you can do so using the following circuit in lieu of using NFC2 as the relay pin, as the I/O Card does. https://docs.particle.io/reference/datasheets/tracker/monitor-one-datasheet/
43/56 2023/9/22 14:58 Monitor One Datasheet | Reference | Particle By disconnecting the VIN power supply, it reduces the current used by the VIN and PMIC voltage regulators. The Monitor One can still be powered by its internal LiPo battery. This is particularly advantageous if the Monitor One is in sleep mode while VIN is disconnected as the power supply loss will be large compared to the very low sleep current in this scenario.

45/56 2023/9/22 14:58 Monitor One Datasheet | Reference | Particle 2 Both internal and external GNSS and cellular are supported by physically changing the antenna connector inside the enclosure. 3 There is no external MCU USB connector on the Monitor One. 4 The Monitor One uses the Tracker SoM BLE chip antenna on the board and does not include a separate BLE antenna, but one could be added using the BLE U.FL connector. 5 The Tracker M uses a shared antenna for BLE and Wi-Fi geolocation. You can use the built-in trace antenna or an external 2.4 GHz/5 GHz dual-band antenna, selectable in software. 6 A small portion of the lash ile system is used by the system, and a conigurable portion can be used for store and forward, to optionally allow location publishes to be saved when the device is oline to be uploaded later. The remainder of the lash ile system can be used by user applications. Schematics https://docs.particle.io/reference/datasheets/tracker/monitor-one-datasheet/

(Guangdong, China) Datasheet Product handling ESD precautions The Monitor One contains highly sensitive electronic circuitry and is an Electrostatic Sensitive Device (ESD). Handling an module without proper ESD protection may destroy or damage it permanently. Proper ESD handling and packaging procedures must be applied throughout the processing, handling and operation of any application that incorporates the module. ESD precautions should be implemented on the application board where the B series is mounted. Failure to observe these precautions can result in severe damage to the module!
