Hi!
I am thinking about implementing an OpenIMU300ZI into my project.
The problem is the following:
I need at least 200 hz data output rate and connect the device via UART.

According to the datasheet:
https://navview.blob.core.windows.net/web-resources/6020-3885-01_G OpenIMU300ZI Datasheet.pdf?_t=1606313626280
the OpenIMU300ZI is capable of providing 200 hz data output rate via UART.

According to the docs on the other hand:
https://openimu.readthedocs.io/en/latest/300ZI/electrical-specs.html
the maximum rate is 100 hz.

Which value is the correct value?

Best,
Y

Hi, I used 200Hz before and OpenIMU300ZI worked properly at that time.
Please note that if the length of packet is a bit long, you also need to adjust baud rate to 230400 or higher.

Hi @ysong,

Please note that if the length of packet is a bit long, you also need to adjust baud rate to 230400 or higher.

how can we set baud rate higher than 230400?
since the available options are
{ "paramId": 2, "category": "General","paramType": "select", "type": "int64", "name": "Baud Rate", "argument": "baud_rate","value_range":[-1,1], "value_accuracy":6, "options": [115200, 57600, 230400, 38400] },
