若要開發與 beacon 相關的應用程式，將需要準備一些硬體，如圖 13-4 中的產品。另外
還有價格較為低廉的選項，讓大家都能無痛進入藍牙技術的領域。
Qualcomm 公司的 Gimbal beacon（
https://store.gimbal.com
）支援 iBeacon 與 Eddystone
兩套格式標準，吸引人注意的是，Gimbal beacon 產品的體積、價格與耗電量，都相
當不錯。關於如何以 Node.js 操作 Gimbal beacon，入門文件可參閱「使用 Node.js 與
Raspberry Pi 來追蹤信標」（

and-raspberry-pi-794afa880318#
）。

RedBear 擴充板和開發板
若你正在尋找相容於 Arduino 的藍牙硬體，那麼必須得看看 RedBear Labs 推出的各種藍
牙產品：
RedBear Duo
此專案最近登上 Kickstarter 群眾募資網站，裡頭包含 BLE 模組與 WiFi 模組，其模
樣請見圖 13-5。這塊板子類似於 Particle 開發板，從圖中你可看出，可加裝電池連
到板子的 VIN 腳位，這麼一來，使得這塊板子適合用於設計響應式環境的情況。
