Regarding power regulators: I have been very happy with https://www.pololu.com/product/2122 on the OMB (comparative list: https://www.pololu.com/search/compare/133 ). Curious: what is your design as of now? Are you "just" using the built in LDO regulator of the Artemis board and / or a LDO on your PCB? :)

gauteh commented 1 week ago

Currently we use the regulator on the notecarrier. Reluctant to use the artemis one since it appears to be less efficient (and it cannot take low voltage).

jerabaul29 commented 1 week ago

Agree that using the Artemis LDO is probably not a good way :) .

I have the PointPerfect account set up from ublox and got us a 2 month free trial of the L-Band broadcasted PPP correction data.

Here is also a link that the support staff sent me on the correct configuration of the combo ZED F9P and NEO D9S board. https://developer.thingstream.io/guides/location-services/pointperfect-getting-started/pointperfect-l-band-configuration

I was also following along with an example setup I found for the combo board and was looking into how to modify this to allow us to log the correction data. This example code configures the combo board through a qwiik connection with another board such as the Artemis nano I have been playing with. It is a little unclear to me if the configuration firmware is saved on the combo board or the main logger using this version. While I think having a firmware code that we can version control and reproduce for other buoys - a lot of the examples suggest using the U-blox platform to set it up.

Sounds great! I think for playing around with the configurations and figuring out what is good, the ublox platform is nice, but at some point we need to send the equivalent parameters over the firmware. We could probably even skip that for now (if we don't have time) as long as the configuration is saved persistently to flash or similar.

That means we run of of the subscription before the experiments, have to remember renewing that before we go.

Sounds good! I will make a note right now to renew the subscription before going in November. I have not activated the subscription yet either so I will activate it as soon as the new board arrives.

Great, thanks!
