Getting two extra pairs of VCC/GND on Arduino Uno (and others) - SyedTips - 4

We often come across projects where we’d like to quickly hook up a sensor or an actuator that works on 5V to an Arduino (Uno and others) without using a breadboard. 42 more words

解難:圖傳訊號間歇地轉弱,跟電流有關 ?

我的 Diatone ET160/150mm (微型無人機) , 在安裝 OSD 之前,圖傳影像流暢。但當加裝 OSD 模組及升級了更大輸出的圖傳輸出後 (由 200mw -> 500mw) ,便發現圖傳訊號會間歇地轉弱、然後畫面跳動,最後就失去影像訊號的問題。 經多過番測試後,發現是由於電壓(V)由高至低轉換後,導至輸出電流 (A) 不足而產生問題。問題成因是跟 Diatone ET160 附帶的 Power Distribution Board 有關,以下的測試例子,表示問題跟 OSD 和圖傳之間的型號配搭無關。 76 more words
