Orange PI - overview of the various boards

There are a bewildering array of models -- and more all the time.

I have two of the "PC" ($15 with 1G and 10/100 network). The "PC plus" adds 8G of eMMMC and wireless (but drops ram to 512M for $20). The "Plus 2e" gives you 16G of eMMC and 2G of ram, gigabit ethernet and wifi, for $35. All of these use the H3 chip.

The "PC 2" is bleeding edge, using the H5 chip.

I am pleased by the devices with onboard eMMC since they can ultimately be used without an SD card. All of these have shipping charges in the $3 to $4 range and may require a microSD card (another $6 or so).

Allwinner SoC chip info

H2 based devices

The Zero is $6.99 and uses the Allwinner H2 chip (32 bit Cortex-A7).

The Zero with 512M is $8.99 (spend the extra $2).

H3 based devices

There are several models based on the H3 SoC:

I bought a pair of the Pi PC to get started. One also has to buy some 8G microSD cards which cost about $5 each, bringing the true cost up to $20. When you consider this, the Pi PC Plus looks quite attractive.

H5 based devices

The Pi PC 2 is $20 and uses the Allwinner H5 chip (64 bit Cortex A53). The word is that the H5 is very similar to the A64, for which data sheets are available. I bought one of these in 11-2016.

H6 based devices

They also have an Allwinner H6 based model (the PC 3). This adds 8G of eMMC and has 2G of ram. The price is $40. The H6 is essentially the same as the H5, but with a different GPU, which I could care less about. You can get it with less ram or without emmc for less money.

Rockchip based devices

The PC 4 uses the Rockchip 3399, which has 6 cores. Two of the cores are the large and faster A72, the other four are A53 like the H5 and H6. Price is $54. You do get 4G of ram and 16G of eMMC. The Orange Pi 4B adds a Gyrfalcon Lightspeeur 2801S Neural Processing Unit (NPU) and costs $77. So for an extra $23 you could get this crazy thing and try to play with it.
