● Shenzhen Xunlong Software社の Orange Pi PC 2を買ってみた
中国深圳のShenzhen Xunlong Software社の製品。
ラズパイを意識した作りで、２匹目のドジョウを狙っているんでしょうか？
ラズパイよりも低価格で高性能です。また、オレンジパイは非常に多くの種類を出しています。
Orange Pi PC 2はその内の一つとなります。
What’s Orange Pi PC 2？
Allwinner H5 Cortex-A53(4core)を搭載
ギガビットLAN
AliExpressの公式ストア（購入はここからできます）
AliExpress - Store: Shenzhen Xunlong Software CO.,Limited
今回は、カメラモジュール付きを 25.30ドルで購入しました。
Orange Pi PC2 set 9 :Pi PC2 and Camera with wide-angle lens not for raspberry pi 2
Price: US $25.30
Shipping: US $3.31 to Japan via China Post Registered Air Mail
Estimated Delivery Time:13-21days
※ 「カメラセット」の「カメラ」を使う方法がまだ分かりません。
※ Orange Pi PC2は電源の相性が有るので「専用電源セット」を購入するのがオススメです。
"Orange Pi PC2 set 4 : Orange Pi PC2 + Power Supply Run Android 4.4, Ubuntu, Debian Image"
専用の携帯アプリでも買い物ができます。
