Monitor One datasheet
Pre-release draft 2022-10-27 for review only. Do not distribute or share this URL!
This is an preliminary pre-release datasheet and the contents are subject to change.

The pictures in this preliminary datasheet are of a pre-release unit. The production units will be a different color, and may have other minor differences.
The Monitor One is an off-the-shelf complete design, like the Tracker One. The Monitor One is in a larger IP67 waterproof enclosure with room inside for expansion cards 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 expansion cards and additional connectors.
- Flexible power supply to easily add asset tracking to most devices with a 6 - 90 VDC power input and a large 18650 LiPo battery pack.
- Internal or external antennas for cellular and GNSS.
- Temperature sensors within the enclosure, and also a battery pack temperature sensor.
- Expansion cards allow for custom features.
- RGB LEDs for system status, and two user RGB LEDs for your own use, visible from outside the enclosure.
- User button, waterproof and accessible from outside the enclosure.

User button
A waterproof button is available from the outside of the enclosure.
- Long press (10 seconds) resets the device (as if the RESET button was pressed)
- Shorter press and multiple press can be handled by your user firmware for your own features
User LEDs (2)
- There are two small RGB LEDs visible from the outside on the side of the unit, next to the user button.
- You can program custom colors, blinking, and fade effects for each LED from your user firmware.
- LEDs are controlled by a ADP8866 I2C LED controller.
Connectors

The bottom plate of the Monitor One can be customized with different connectors for your application.

By default the Monitor One uses the internal cellular and GNSS antennas, but can be switched to using the external connectors inside the enclosure.
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 facing down 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 any direction.
The mounting plate contains two magnets that allow it to be easily mounted on a metal surface, or to a metal plate affixed to a non-metal surface, such as the wood post shown above.

The mounting plate is removable from the back of the unit after removing the screw on the bottom, near the expansion connectors.
Once removed, you can screw or bolt the mounting plate to a surface and reattach the Monitor One. This is good for rough conditions and to help prevent theft.

Expansion card interface
Tracker M is designed with easy-to-use expansion headers and an enclosure with sufficient space inside for an expansion card, and for additional expansion connector through the wall of enclosure.
- Expansion card size: 50mm x 90mm (approximately 2" x 3.5")
- Connectors: 24-pin 0.1" headers (two, one on each long side)
- Male header pins on the bottom of expansion card
- Attachment: 4 screws to standoffs (M3 screw recommended)
Pre-built expansion cards will be available, including a prototyping breadboard expansion card. You can also design and fabricate your own.

The standard M12 connectors are IP67 waterproof (connected or not), 12 mm in diameter, and have 8 pins or 4 pins. However, M12 connectors are available from 2 pin to 17 pins. The connectors with smaller numbers of pins often have higher voltage and current ratings.
The panel-mount 8-pin connector on the Monitor One is female, with the following pinout:

The panel mount M12 8-pin connector fits in the following hole in the enclosure:

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 flowing 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 difficult if you've sealed your Monitor One enclosure.
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 off 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:

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.

1On the Tracker One, the M8 can be configured for GPIO, I2C (SDA and SCL), or Serial (RX and TX) on two pins.
2Both internal and external GNSS and cellular are supported by physically changing the antenna connector inside the enclosure.
3There is no external MCU USB connector on the Monitor One.
4The 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.
5The 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.
6A small portion of the flash file system is used by the system, and a configurable portion can be used for store and forward, to optionally allow location publishes to be saved when the device is offline to be uploaded later. The remainder of the flash file system can be used by user applications.

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!
Battery warning
CAUTION
RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE. DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS.
Disposal
This device must be treated as Waste Electrical & Electronic Equipment (WEEE) when disposed of.
Any WEEE marked waste products must not be mixed with general household waste, but kept separate for the treatment, recovery and recycling of the materials used.
