Transpeed P10 Android 10 Full HD projector features Allwinner H700 SoC

Allwinner H700 is a “new” processor that has found its way into Transpeed P10 Full HD “portable” projector running Android 10. It is sold on Aliexpress for $125 including shipping.

Allwinner H700 happens to be yet another derivative of Allwinner H616/H618 quad-core Corex-A53 processor, but adds an RGB LCD interface up to 1080p60 and video input interfaces that make it suitable for projector and smart displays. The processor also has two Ethernet interfaces (1x Gigabit and 1x 10/100M) like the H616, but no built-in PHY, so an additional Ethernet transceiver is needed on the board.

Let’s first have a look a the Transpeed P10 projector specifications:

• SoC – Allwinner H700 quad-core Arm Cortex-A53 processor @ 1.5GHz with Arm Mali-G31 mp2, 6K video decoder, and 4Kp25 H.264 video encoder
• System Memory – 2GB  RAM
• Storage – 16GB eMMC flash
• Projector
  • 1920×1080 native resolution
  • LED bulb
  • Brightness – 120 ANSI Lumens
  • Projection distance – 1.8 to 6.6m (image: 35-inch to 200-inch)
  • Contrast:1500:1
  • Manual Correction (Keystone)
  • Manual focus
• Video Input
  • 1x HDMI input port (The specs say 2x HDMI input, but I can find the second one)
  • AV port with composite and stereo audio
• Audio – 3.5mm audio jack
• USB – 1x USB 2.0 port for storage, keyboard, mouse, etc…
• Connectivity
  • Dual-band 802.11ac WiFi 5 and Bluetooth5.0 via AW859A wireless module
  • Wireless display support
• Power Supply – 19V DC via power barrel jack
• Dimensions – 135 x 107 x 145 mm
• Weight – 1.6 kg

The device ships with a remote control, a power supply, and a user manual. Allwinner H700 is using the same Android 10 SDK as Allwinner H616, and not the more recent Android 12 SDK for Allwinner H618. The projector does not have a battery, so the only reason it is “portable” is because of the hand strap and relatively small size.

Contrary to H618, Allwinner has published the datasheet for Allwinner H700 processor, and the block diagram is exactly the same as for Allwinner H616, except for the RGB LCD interface, the “Image In” interfaces (4-lane MIPI CSI and 16-bit paralle CSI), the Ethernet 10/100M PHY is gone, a new 4-channel GPADC block is shown, as well as an “SCR” block meaning “Smart Card Reader” for encrypted digital TV.

The applications block diagram shows the MIPI-CSI and BT1120 parallel CSI interfaces used for HDMI input or camera input, the RGB/LVDS interface connector to an LCD display, or in the case above a projector with the LRADC used for a keypad.

There’s no battery support, so it’s not suitable for tablets like the Allwinner A-series processor. Maybe the Allwinner H700 processor could be interesting for other HDMI input applications as well such as a low-cost PVR with USB 2.0 storage.
