Hello, are they fully compatible with each other?

Should be fine, it uses standard UART Pinouts | Adafruit Ultimate GPS featherwing | Adafruit Learning System

Thanks. Does the combo allow me to capture analog data at 1msec resolution?

No, it allows you to capture GPS data.

What product allows me to do that? Previously I bought an Adalogger FeatherWing with RTC but the clock is at 1sec resolution. The resolution is too low and some changes in analog sensor data were not captured/saved. I want to get the data of time [msec] and corresponding sensor reading ideally in indoor environment.

GPS doesn’t work well indoors, the antennae need a clear view of the sky

GPS boards usually report at 10Hz…while the Thing Plus can certainly do analog data @ 1ms, coordinating those readings with GPS requires the GPS module to wait and have satellites pass by before updating. You could log analog data every 1 ms, but GPS updates will be less frequent

You might be able to edit the RTC logger’s code to log faster

OK. Forget about the GPS then…

If I want something like:

0 msec, corresponding output from sensor
1 msec, corresponding output from sensor
2 msec, corresponding output from sensor
:
1000 msec, corresponding output from sensor
:
10000 msec, corresponding output from sensor

Do you have any product that can get this job done? If not, how about 10, 20, 50 or 100 msec intervals? Of course the shorter the interval the better.

The Adalogger RTC cannot do 1msec time interval.

SparkFun OpenLog Artemis - SparkFun Electronics can do 1900Hz analog; see OpenLog Artemis Hookup Guide - SparkFun Learn

Thanks. Can the built-in IMU report the absolute orientation about the X, Y and Z axes accurately in degrees? How is it compared with the BNO055 which I have been using? Can I integrate the BNO055 to this OpenLog Artemis to get the absolute orientation?

Yes. Compare their specs. Yes but not easily, but why bother if you can use the built-in one?

Thanks. If the built-in one can also report accurate absoluate orientation, sure I shall use the built-in one.

  1. When you said it can do can do 1900Hz analog, you mean the time intervals can even be 1/1900=0.53msec? How many channels of analog data at 1msec?
  2. Is the microSD socket using SDIO? Not mentioned in the specs. If it is slower than the one in ESP32-S3 Think Plus, can I use the one in the Think Plus.
  3. The video shows that it starts data logging when a button is pressed. Can this also be controlled by software running in the ESP32S3 Think Plus?
  4. What battery is needed for the RTC. There is no mention in the specs.
  5. Looks like the Artemis is a standalone product. Can it be connected to the ESP32S3 Think Plus and act like other breakout boards that can be fully controlled by the ESP32S3 and Arduino C++?

Please review the docs/materials.

  1. 3
  2. No
  3. Yes
  4. It comes with it, specs in schematic
  5. No
