Orange Pi One
This is the little brother to the Orange Pi PC.
It has half the RAM (i.e. 512M rather than 1G),
other than that it is effectively the same.
You save $5 (It costs $10 rather than $15).
I don't own one of these, and perhaps never will
(I would rather spend $20 and get the PC Plus with
onboard eMMC and 1G of ram).
- Allwinner H3 SoC
- Quad Core 1.6 Ghz ARM Cortex A7 cpu
- Processor with 256K L1 and 1M L2 cache
- *** 512M of ram
- SD slot
- 10/100 Ethernet
- Three USB 2.0 connectors
- One USB "OTG" connector
- 40 pin IO connector "Pi B+ compatible"
- 85 by 55 mm in size
- 3 pin uart header
- two on-board LED's
- reset button
- Mali GPU (I never intend to use this).
- HDMI connector
- Camera connector
- Audio out via 3.5 mm jack
- IR sensor
- $10 on AliExpress
For those who don't want to endure the pain and suffering of patching and building,
Looking at the U-boot config files, I find that the "PC" has some kind of i2c bus
power control chip and this option is set for the "PC" and not for the "One".
To build U-boot (I use the v2016.11 sources with Armbian patches), I do:
The result that I really want is the file:
cp u-boot-sunxi-with-spl.bin ~/u-boot-orangepi-one-with-spl.bin
Have any comments? Questions?
