Points distinguishing this board from others:

  • Raspberry Pi 3 compatible form factor
  • eMMC 4.x module port (8/16/32/64/128GB)
  • CE/FCC certification
  • Big push-pin heatsink with thermal tape, covering SoC and ram
  • Quality components, tier-1 ram chips

This board is produced in white colour and has 3 variants that only differ in SoC/ram used:

  • ALL-H3-CC H2+ 512MB (Tritium IoT)
  • ALL-H3-CC H3 1GB (Tritium 1GB)
  • ALL-H3-CC H5 2GB (Tritium 2GB)

Otherwise dimensions, component and port locations are identical.

Sunxi support

Current status

Give a brief overview of the current status of support under sunxi here.

Images

Optional. Add MANUFACTURER DEVICE specific sunxi ROM images here. E.g. a livesuit image or some other linux image which uses linux-sunxi code. Do not put non-sunxi images here, they should live under See also. If no sunxi based images are available, this section can be removed.

HW-Pack

Optional. Add MANUFACTURER DEVICE sunxi HW-pack specifics here. When empty, this section can be removed.

BSP

Optional. Add MANUFACTURER DEVICE sunxi BSP specifics here. When empty, this section can be removed.

Manual build

You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.

U-Boot

Tips, Tricks, Caveats

Power

MicroUSB power is routed through 2A fuse (1F1). Connecting power through GPIO pins bypasses over voltage protection circuit. Each of USB-A jacks is routed through 500mA fuse (so you can not connect 1A HDD, also, you can not draw more than 500mA combined from the same dual-jack).

CPU power

H2+ and H3 boards supply single 1.2V to CPU using AXP8036 (1.1V on H5), which means maximum cpu freq is limited to 1008MHz.

USB-OTG

USB-OTG port is located in one of USB-A jacks. That's top left one on v1.0.

FEL mode

The something button triggers FEL mode.

Buttons

  • UBOOT (K1)
  • Power (K2), PL2

LEDs

The board has three LEDs:

  • Blue LED (Status), connected to the PA07 pin.
  • Green LED (Power), connected to the PL10 pin.
  • Red LED, connected to the VCC3V3-IR.

Locating the UART

The UART pins are located between HDMI and power jack on the board. Marked on the PCB (simplified layout: ..board-edge..GND|TX|RX. Just attach some leads according to our UART Howto.
