OPEN (default): GPIO3_1 will be pulled high. Getting Started Prerequisites Before you power up your HiKey board for the first time you will need the following: HiKey board. A power supply with 12V@2A (suggested). A HDMI or DVI LCD Monitor. -
Page 9: First Power On
First Power ON To start the board, follow these simple steps: step 1.Connect the HDMI cable to the HiKey HDMI connector and to the LCD Monitor. step 2.Connect the keyboard to the boards USB connector and the mouse to the USB connector. -
Page 10: Memory (Dram)
1-channel 19.2M digital clock output. Memory (DRAM) The HiKey (LeMaker version) uses a LPDDR3 DRAM chip as the memory. It provides 1GB or 2GB DRAM memory to satisfy the different requirements. a single embedded Multi Chip Package (eMCP) dual function LPDDR3/eMMC memory solution. -
Page 11: Display Interface
The ADE supports the RGB parallel interface that can connect to display interface IPs such as the MIPI DSI and HDMI. Below is a block diagram of the HiKey implementation. HDMI The Kirin 620 doesn’t include a built-in HDMI interface. The Kirin 620 deploys the built-in MIPI-DSI 4 lanes interface as the source for the HDMI output. -

H igh Speed Expansion Connector USB Ports There are a total of 4 USB ports on the HiKey board. Two Type-A host ports at J401 and J403, one microUSB AB 2.0 host/slave port at J402 and one USB host port available on the High Speed Expansion bus. -
Page 13: Audio
Audio The HiKey board uses HDMI audio as the audio output. It also has a PCM channel on the Low Speed Expansion connector. DC Power The 96Boards specification calls for power to be provided to the board in one of the following ways: An 8V to 18V power from a dedicated DC jack . -

HiKey is located beside the BT LED, this LED reflects the status of the Wi-Fi device. The BT activity LED is a Blue Type surface mount 0603 LED. The BT LED on the HiKey board is located next to the USB OTG connector; this LED reflects the status of the Bluetooth device. -
Page 15: Additional Functionality
The four user LEDs are surface mount Green Type 0603 LED. Additional Functionality JTAG The HiKey board includes the option for soldering a 10 pin header that brings out the SoC signals for JTAG debug. A FTSH-105-01-F-DV header can be populated at J803. Expansion Connectors The HiKey board features two expansion connectors: one low speed expansion connector and one high speed. -

The GPIO3−GPIO19 pins are multiplexed with other functional pins. SPI 0 The HiKey board implements a full SPI master with 4 wires, CLK, CS, MOSI and MISO all connect directly to the Kirin 620. 16/22... - Page 17 The HiKey board implements a PCM with 3 wires, CLK, FS and DO, the optional DI signal is not implemented on the HiKey board. The I2S signals are connected directly to the Kirin 620. Power and Reset The HiKey board routes the PMU_PWRON_N signal to the PWRON_N pin of the HI6553V100 PMIC.

- Page 19 The HiKey board implementation supports a full four lane MIPI-DSI interface that is routed to the High Speed Expansion Connector. Since the Kirin 620 has only single MIPI-DSI interface and it may be used to drive the DSI-HDMI Bridge, DSI Muxing is required.
- Page 20 SoC and the set of peripherals that are specific to that implementation. The HiKey board uses two buck regulators, U302 and U301. U302 takes the power into the board and generates 5V at 4A. This voltage feeds the USB HOST power limit switches and provides power to the Low Speed Expansion port.
- Page 21 Please note: t he SYS_DCIN can be as low as 6.5V on the HiKey board. The power supply which is used to power the board from the DC jack should be positive outside and negative inside. 2. 8V to 18V supply from the SYS_DCIN pins on the Low Speed Expansion Connector.
