micro：bit v2是流行的袖珍可編碼計算機的全新超級充電版本，它通過麥克風，揚聲器和升級的處理功能帶來了最新的發展
micro:bit v2 is a brand new, super-charged version of the popular pocket-sized codeable computer, brought bang up to date with a microphone, speaker and upgraded processing capabilities.
micro：bit v2是流行的袖珍型可編碼計算機的全新超級充電版本，它通過麥克風，揚聲器和升級的處理功能帶來了最新消息。
With over four times the processing power and eight times as much RAM as the original micro:bit this new model opens up a world of new possibilities! We're especially excited about how well MicroPython will run on the new model where previously the limited RAM was a struggle.
擁有超過四倍的處理能力和八倍之多RAM作為原始微：位這種新模式開闢了新的可能性的世界！我們對MicroPython在新模型上運行得如何感到特別興奮，而以前有限的RAM一直是個難題。 操作影片-1：https://youtu.be/pIUJ4kvJ_QU
