Hi @18257581
Sometimes our newer boards are lacking in full documentation, so thanks for your patience.
We have not publicly posted our uCoax pinouts and not sure yet if we plan to. For now it is required to use our full solution which is host adapters, cables, and sensor boards.
I'll bring it to the team. But, we are unlikely to open this up since in order for us to test the components, which are very fragile, they need to be bundled together and not separated, so it would actually cost us more (costing our customers more) to test units individually for customer designs.
Only the Coax cable we sell individually and that is pinned 1:1 with all 26 conductors present unlike some of the other COTS FPV systems.
However, for JST and other cable-to-board and board-to-board connectors, yes, we need to get that listed.
The pinout on J4 of M0201 (the replacement for M0153) is in the same Dronecode inspired format we use at ModalAI for UART + I2C, but in this case since it is not UART, it is 2 GPIOS.
So,
Pin 1 = 3.3V
Pin 2 = GPIO_1 (Undefined/Unavailable/Reserved for Future Use)
Pin 3 = GPIO_2 (Undefined/Unavailable/Reserved for Future Use)
Pin 4 = GIMBAL_I2C_SDA (3.3V Logic Levels, 2.2K pull-up resistor present)
Pin 5 = GIMBAL_I2C_SCL (3.3V Logic Levels, 2.2K pull-up resistor present)
Pin 6 = GND
