HL-2154R PCB Layout 零件圖檔 PCB & DXF

HL-2541R-UC是BLE Central端. 能快速自動的搜尋并連線附近的HL-2541R-UP(BLE Peripheral端).

本模組能快速直接升級傳統UART成為無線藍牙傳輸, 讓將有線的UART設備簡單的轉換為藍芽無線
傳輸. 可適用RFID, 血壓計, 條碼掃描器, 字幕機, 藍芽實驗, 專題製作 ... ...

採最新藍牙v4.0 BLE技術, 與傳統藍牙和無線網絡相比功耗更低, 連接速度更快.

本款內建天線設計, 解決DIY天線的困惱, 避免造成天線不匹配、訊號強度損耗、訊號反饋等情況. 本
款解決這個惱人的RF問題,將2.4GHz天線內建置模組內,讓您輕鬆徜徉體驗藍海。

主要特色:

●採用 Bluetooth v4.0 BLE 低功耗晶片

●支援 BLE Peripheral

●UART TTL界面

●接收距離可達10~30公尺(開放空間環境)
