Have you wrote to Holybro?
6X power connector supports I2c signals. If you follow the connection, and setting, you should write to Holybro.
Do you think you are using a older version of PM02D? What is your module hardware version? It said HV-v1.4. A clearer picture of connection.
I am disappointed with Holybro’s marketing their product with the same product name for two different usage sets, using the hardware version as the variance.
for example Cubepilot Power signal which work with PM02 V3. Holybro should rename the product to something like PM02-I2C, for example. do you see a “D” on your part?
