$20 pcDuino4 Nano is Yet Another Allwinner H3 Development Board (Sort of)

Orange Pi Development Boards

We already have plenty of low cost Allwinner H3 development boards thanks to several Shenzhen Xunlong Orange Pi boards and FriendlyARM NanoPi boards among a few others. Here comes another one with pcDuino4 Nano.


pcDuino4 Nano (preliminary?) specifications:

  • SoC – Allwinner H3 quad core Cortex A7 @ 1.2 GHz with an ARM Mali-400MP2 GPU up to 600 MHz
  • System Memory – 1GB DDR3 SDRAM
  • Storage – micro SD card slot
  • Video & Audio Output – HDMI and 3.5mm jack for CVBS (composite + stereo audio)
  • Connectivity – 10/100M Ethernet
  • USB – 3x USB 2.0 host ports, 1x micro USB OTG port
  • Camera – DVP Interface
  • Expansions – 40-pin Raspberry Pi compatible header with UART, SPI, I2C, PWM, GPIOs, etc…
  • Debugging – 4-pin header for serial console
  • Misc – Power and reset buttons; 2x LEDs; IR receiver; on-board microphone.
  • Power Supply – 5V/2A via micro USB port; 5V via VDD_5V pin on 4-pin serial header.
  • Dimensions – 64 x 56 mm

Hmmm.. that board looks familiar…, and the specifications are exactly the as NanoPi M1 board, and actually copied / pasted from that post on CNX Software… The main difference appears to be that the PCB will be white instead of blue. I don’t know if FriendlyARM and pcDuino cooperated, and the latter simply copied the design, but we’ll find out very soon [Update: FriendlyARM is manufacturing the board for pcDuino]. For documentation, I’ll just refer you to NanoPi M1 Wiki

pcDuino4 Nano can be pre-ordered for $20 + shipping ($20 extra in my case) with delivery scheduled to start on September 24th. For reference, NanoPi M1 board with 1GB RAM is now sold for $16 + shipping ($5).

Considering the price, I would rather continue purchasing Oranges …


Whats the point when H5 is right around the corner ?


That’s definitely not for $20.
I wonder who will buy this overpriced board while Orange pi’s (PC or One) are floating around with one-fourth of the price of this


Funny. Orange Pi PC has exactly the same feature set, the better voltage regulator allowing to clock faster (1.3 GHz) and is way cheaper if shipping costs are also considered. ‘Power Supply’ and ‘Dimensions’ are wrong in description above and on seller site.


Dimensions are now correct, powering is also possible through the 4 pin header (pin 1 GND, pin 2 VDD_5V) but that’s not that important since I doubt they will also sell FA’s nice PSU-ONECOM module (very convenient!)


Not only that, I read that Orange Pis have some ‘heatsink’ inside the circuit board, which makes the CPU a bit cooler. The NanoPis run hotter.


FriendlyARM fixed at least with the NEO some thermal problems with PCB revision 1.1: http://forum.armbian.com/index.php/topic/1580-nanopi-neo/?p=15635

Maybe they come up with similar fixes for the M1 too… but it’s true that even the small Oranges remain cooler than NanoPi M1 due to ground plane acting as one large heatsink.
