--- title: 懶人包:我要如何購買 Meshtastic 裝置 / DigiResiTh0n tags: digital-resilience, resilience, internet-shutdown, digiresi, civil-defense, 民防, 數位韌性松, DigiResiTh0n, hackathon, meshtastic, mesh, lora --- # \[懶人包\] 我要如何購買 Meshtastic 裝置 作者:@dryden(g0v slack) source: https://www.facebook.com/groups/meshtastictw/posts/434624832280048/ [](https://www.facebook.com/groups/413628121046386/user/1648816647/) Meshtastic 使用的是 LoRa 的傳輸技術,而 LoRa 的特色是,在可以直視目標物且沒有阻礙物的狀況下,傳輸距離可以達到數十甚至數百公里。但一旦中間有建築物阻擋,訊號傳輸的距離就會大幅下降到十公里以下。 而在都市裡,高樓大廈會讓 Meshtastic 的傳輸距離下降,因此在此會推薦購買兩種裝置,**手持的 Meshtastic 裝置**與 **Meshtastic 太陽能節點裝置、自製窗邊節點**: ##### **手持的 Meshtastic 裝置** - 最適合入門的是 Heltec v3 ESP32 這台,可以直接在蝦皮的官方店購買到原裝版本、或是預安裝好 Meshtastic 版本。 · 需要自行參考教學文,透過電腦將 Meshtastic 韌體刷入,並在 app 內完成設定 · 購買連結 https://heltec.cashier.ecpay.com.tw/product/000000000612179 (可使用本社團專屬限量折扣碼 MESHTW101) · 頻率請選擇 863-928,才符合台灣法規(台灣用的是 923) · 配件爲鋰電池,若是搭配購買,未來在使用時會比較方便。 · 若沒有選購鋰電池,可以透過行動電源 + USB type-c 來供電。 ##### **放置於高樓頂端的 Meshtastic 太陽能節點裝置** 高樓樓頂因爲比較不會受到建築物的阻礙,可以發揮 Meshtastic 長距離傳輸的特色,因此當一個城市中,大樓的樓頂都裝設了節點,就可以確保訊息可以互相串聯,傳送到遠處,將網路覆蓋範圍擴展開來。但由於高樓樓頂的電力往往不易取得,又或是考量到大型災害時需要確保大樓節點可以正常運作,因此推薦在高樓樓頂放置太陽能節點。 而目前在台灣尚未有廠商推出整套的 Meshtastic 太陽能裝置。 - 因此可以選擇自行購買太陽能板、防水盒、充電電池、天線,組合出適合的太陽能節點 - 或是購買由板主我,將市售太陽能電池改裝後製作的太陽能節點 · 根據使用的開發板不同,分爲兩種版本 · 使用 Heltec v3 開發板,搭配 3 顆 18650 鋰電池 ·· 開發板成本較低、且容易取得,但開發板本身相對耗電,因此較適合放置在日照多的地區,例如臺灣南部 · 使用 RAK 開發板,搭配 2 顆 18650 鋰電池 ·· 開發板更省電,因此更適合用於太陽能裝置,尤其是容易多天不見太陽的台灣北部地區。但台灣沒有官方代理,需要從海外購入,成本較高。 · 購買連結 https://myship.7-11.com.tw/general/detail/GM2403162994445 ##### **放置於窗邊的 Meshtastic 自製窗邊節點** 畢竟不是每個人都有頂樓可以使用,但絕大多數的人都可以在窗邊放置一個節點,也對於提升整個區域的訊號有幫助! 會需要以下配件 - Heltec v3 開發板一個 - 塑膠盒一個(我使用的是 18650 電池盒,需要自己動手挖兩個洞) - USB type c 電源線一條、USB 充電器一個 - 品質良好的天線一個 組裝成果可以參考附圖,如果需要購入材料,一樣可以參考這個購買連結 https://myship.7-11.com.tw/general/detail/GM2403162994445 看完後如果有疑問,可以在爬完其他人的留言以後,在底下留言發文唷 下一篇:\[懶人包\] 購買後要如何設定 - 刷韌體 https://www.facebook.com/groups/meshtastictw/permalink/414578450951353
