Just for a context, There are two methods to fetch the data from server using GSM/LTE module. a] File download to module's FS b] partial data fetching uisng HTTP-GET method Bothe methods are working fine, but [a] is less time consuming, so we picked it. Last but not least, esp3...

问试图理解GSM代码上的ESP32 OTAEN看@FrostMiku最近一直在玩ESP32，而且看起来真的很有趣，所以就求了个链接买了一块板子自己玩。咱也很想玩玩嵌入式嘛。不过ESP32的板子倒是真便宜，基本都在二三十左右。我这块由于带了个TFT屏，所以稍贵，价格是38。到手之后发现屏幕虽然不大，但是分辨率有135×240，所以整体...

I use a buck converter to produce 4V for the GSM modem. I use another buck converter to provide 5V for the rest of the circuit. I use an LM117-3.3 to provide 3.3V for the ESP32 and the GPS module. All works perfectly on breadboard. However, when I built a custom PCB of it, th...
