(*) ODrive v3.5 and later
(+) On ODrive v3.5 and later these pins have noise suppression filters. This is useful for step/dir input.

Notes

• Changes to the pin configuration only take effect after odrv0.save_configuration() and odrv0.reboot()
• Bold font marks the default configuration.
• If a GPIO is set to an unsupported mode it will be left uninitialized.
• When setting a GPIO to a special purpose mode (e.g. GPIO_MODE_UART_A) you must also enable the corresponding feature (e.g. <odrv>.config.enable_uart_a).
• Digital mode is a general purpose mode that can be used for these functions: step, dir, enable, encoder index, hall effect encoder, SPI encoder nCS.
• You must also connect GND between ODrive and your other board.
• ODrive v3.3 and onward have 5V tolerant GPIO pins.
• Simultaneous operation of UART_A and UART_B is currently not supported.
