10/28 在 Amazon.com 購買了這個型號的 DC Converter 共 6 顆,11/10 就收到貨了,速度還蠻快的。
攤提運費後,一顆約要 NT $160 元,不算便宜,但買得到比較重要。

Attention :
This is a DC-DC voltage converter module,Must be noted when using:
1 Input voltage can not be greater than the maximum input range
2 Output power can not be greater than the maximum load for a long time
3 Input power must be greater than the output power, because the power consumption of the module itself

原本是想配合 4 顆 AAA 鹼性電池,再做一個新的 ESP8266 翻頁器,買了才想到 AAA 電池出廠電壓有可能超過 1.5V,故 4 顆串聯可能會超過電壓工作範圍,如果是 3 顆串聯又達不到我想把電池用乾的需求,因為其最低工作電壓只到 3.5V。看來還是只能配合 18650 等電池使用。
這個大小比我之前買的升壓 Converter 都還要更小,也就是說更考驗焊接技術了。
