## Hardware

- HPM6360IPA MCU
- Onboard Memory
  - 16bit 256Mb SDRAM
  - 128Mb Quad SPI NOR Flash
- USB
  - USB type C (USB 2.0 OTG) connector x2
- Ethernet
  - 100Mb PHY
- Others
  - TF Slot
  - CAN FD
  - FT2232
- Expansion port
  - Motor control port
  - Raspberry PI extension port

:::{note}

The sdram pins are multiplexed with the 15-20pin of the motor interface J26, so the motor interface and sdram can't be used at the same time.
