- Grove コネクタを搭載 - 2、3 つのスルーホールが接続された状態になっており、ワイヤーを挿入してはんだ実装することができる（通常のユニバーサル基板はワイヤー実装面でスルーホールに挿入せず、スルーホール上のランドに接続して実装する） - 電源 5V 供給時に、3.3V を使用できるレギュレータを追加可能にする - ジャンパ JP1 を接続すると、ユニバーサル基板上の VCC に Grove の VCC を直結させることができる - I2C 用のプルアップ抵抗を接続可能

シルクでラインで繋がれたスルーホール同士は接続しています。ワイヤーを差し込んで配線することが可能です。一般的なユニバーサル基板とは異なることを留意してください。
