良好なパッケージ、良好な状態で受け取ったと優れた納期 ( 注文から11暦日)。 これは、一般的にLCDバックパックとしてではなく、一般的な「ポートエクスパンダ」として使用します。 PCF88574は非常に有用であり、私は強くお勧めします。

Well packaged, received in good condition and excellent delivery time ( 11 calendar days from order). I generally use this as a general "Port expander" rather than as an LCD back pack. The PCF88574 is super useful and I highly recommend it.
