Sparkfun SparkFun MicroMod Asset Tracker Shield
###############################################
Overview
********
The SparkFun MicroMod Asset Tracker Carrier Shield is part of the Sparkfun
Micromod standard, a modular interface ecosystem that uses the M.2 standard
to mix and match your choice of processor with specific Functions Boards.
The Asset Tracker Carrier Shield is built around the u-blox SARA-R510M8S
module, which offers Secure Cloud LTE-M and NB-IoT data communication for
multi-regional use and GNSS capabilities via an integrated u-blox M8 GNSS
receiver for accurate positioning information.
Besides, this shield has an integrated ICM-20948 Inertial Measurement Unit
(IMU) for Nine Degree-Of-Freedom, a built-in micro-SD card socket for data
logging as well as a nano SIM card port.

Programming and Debugging
*************************
Applications for the ``micromod/nrf52840`` board target can be
built, flashed, and debugged in the usual way. See
:ref:`build_an_application` and :ref:`application_run` for more details on
building and running.
Flashing
========
Follow the instructions in the :ref:`nordic_segger` page to install
and configure all the necessary software. Further information can be
found in :ref:`nordic_segger_flashing`. Then build and flash
applications as usual (see :ref:`build_an_application` and
:ref:`application_run` for more details).
The flashing tool will depend on the carrier used along with the board.
In the case of `Sparkfun asset tracking carrier`, it is possible to use
the SWD interface along with a J-Link.
Here is an example for the :ref:`hello_world` application.
First, run your favorite terminal program to listen for output.
.. code-block:: console
$ minicom -D <tty_device> -b 115200
Replace :code:`<tty_device>` with the port where the board nRF52840 DK
can be found. For example, under Linux, :code:`/dev/ttyACM0`.
Then build and flash the application in the usual way.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: micromod/nrf52840
:goals: build flash
Debugging
=========
Refer to the :ref:`nordic_segger` page to learn about debugging Nordic boards with a
Segger IC.
In case of using a Nordic Segger Jlink, it is possible to configure the app to use Segger Real
Time Transfer (RTT) for debugging. In this case, build your app with the
:ref:`RTT snippet <snippet-rtt-console>`.
Testing the on-board LED
************************
There is a sample that allow you to test the LED on the board is working properly
with Zephyr:
* :zephyr:code-sample:`blinky`
You can build and flash the example to make sure Zephyr is running correctly on
your board. The button and LED definitions can be found in
:zephyr_file:`boards/sparkfun/micromod/micromod_nrf52840.dts`.
Testing the 128Mb qspi memory flash
***********************************
The ``micromod/nrf52840`` board target has a built-in NOR flash memory connected
to the qspi interface. It can be tested with the samples/drivers/jesd216 app.
.. zephyr-app-commands::
:zephyr-app: samples/drivers/jesd216
:board: micromod/nrf52840
:goals: build flash

GPIO pins exposed on micromod headers.
The micromod standard leverages the M.2 connector with 76 pins for
swap between a myriad of supported boards and carriers.
The micromod standard consists of two lanes with the following
supported buses:
* An 6-pin Power Supply header. No pins on this header are exposed
by this binding.
* Reset, Boot pins and SWD pins not exposed by this binding.
* 2 UART buses. First with RTS and CTS pins, while the 2nd with only
RX and TX pins. Neither of them are exposed by this binding.
* 2 i2c buses. Only the corresponding interrupt pin is exposed by
this binding.
* 2 SPI buses not exposed by this binding. Only SPI CS control pin
is exposed by this binding.
* Audio line not exposed by this binding.
* 2 analog pins (A0 and A1).
* 2 digital pins (D0 and D1).
* 12 General purpose pins (G0 - G11).
This binding provides a nexus mapping for the analog, digital and
general purpose gpios in the order depicted below:
- 00 -> A0 PIN 34
- 01 -> A1 PIN 38
- 02 -> D0 PIN 10
- 03 -> D1/CAM_TRIG PIN 18
- 04 -> I2C_INT# PIN 16
- 05 -> G0/BUS0 PIN 40
- 06 -> G1/BUS1 PIN 42
- 07 -> G2/BUS2 PIN 44
- 08 -> G3/BUS3 PIN 46
- 09 -> G4/BUS4 PIN 48
- 10 -> G5/BUS5 PIN 73
- 11 -> G6/BUS6 PIN 71
- 12 -> G7/BUS7 PIN 69
- 13 -> G8 PIN 67
- 14 -> G9/ADC_D-/CAM_HSYNC PIN 65
- 15 -> G10/ADC_D+/CAM_VSYNC PIN 63
- 16 -> G11/SWO PIN 8
- 17 -> SPI_CS PIN 55
