好消息是目前 Pi 4 有小改版，型號為 v1.2。根據 theregister 的報導，新版修正了 USB-C 的供電問題，可適用大部分的充電線(器)。此外，新版還進行了絲印的調整，可以減少焊接過程中發生錫橋。
檢查的方式是在命令列執行 cat /proc/cpuinfo，如果是 Pi4/4GB 在版本號(Revision)的部份會顯示 c03112，型號(Model)會顯示 Raspberry Pi 4 Model B Rev 1.2 就是新版(v1.2)。如果在 Revision 顯示 c03111，Model 顯示 Raspberry Pi 4 Model B Rev 1.1 那就是舊版(v1.1)。我們販售的 Pi 4 都是新版。

Raspberry Pi Jam in Taipei 2020 是一個慶祝樹莓派生日的活動。樹莓派到了今年春天已經是第八年了，所以樹莓派基金會籌劃了這樣的活動：”慶祝來自世界各地的樹莓派的生日”。
從 2/15 和 3/15 這段期間，全球各地會有超過一百個慶祝活動，我們舉辦的 Raspberry Pi Jam in Taipei 2020 會在台北一同響應，活動將在 3/14 邀請各地的朋友分享有趣的專案，也會邀請之前的講者一起來聊聊天，並且發放 Raspberry Pi Jam 小禮物。
這次活動的內容包括有︰
1. 披薩和可樂 ==> 對的，這是慶生會必要的餐點!
2. 閃電秀分享。
閃電秀持續更新中…
