Description

 

micro:IO-BOX 是一款micro:bit多功能擴展板,帶有板載鋰離子電池電源,外觀精美,易於使用。在6cm×6cm板上集成了許多功能,例如2路驅動器電機,9路IO端口,2路I2C端口,1路串行端口,1路蜂鳴器,4路RGB LED,鋰離子電池電池盒,充電電路,應急電源接口等。產品亦有一個外部保護罩,以使其更加耐用和堅不可摧。 此外,我們還密切關注產品使用的安全性,特別是為兒童設計的產品。在市場上,當前,一些製造商為其產品採用18650電池。 但是,這種電池由於其高容量和大尺寸而有爆炸的風險。 因此,經過長期測試,產品使用了1000mA的CR123A 3.6V鋰充電電池。 這種電池體積小,容量大,安全性高。此外,產品亦設置了短路和反向連接保護,以進一步提高使用鋰離子電池的安全性。 

為了提供穩定的電源,micro:IO-BOX採用了高成本的升壓/降壓電源管理解決方案。眾所周知,摩打在啟動時的瞬時電流可以達到1A,這對電源供應來說是一個巨大的挑戰。因此,產品進行了嚴格的測試:使兩個TT摩打保持正向和反向連續旋轉,即使在這種情況下,電路板和摩打仍可以工作約1.5個小時,直到耗盡電池為止。在正常操作中,電池可以工作6個小時以上。 

FEATURES 

  • 使用時間平均達6小時(實際時間可能因使用情況而與說明有所不同)外部電源:3.7V〜5V 
  • 充電接口:microUSB 5V  
  • 支援的摩打電壓:3V〜6V
