Based on the ESP8266 module, this WeMos D1 Mini makes programming and interfacing a breeze. With its built in reset/programming circuitry you no longer have to worry about pressing any buttons when uploading your code to the device. It also comes with a handy micro USB jack for power and communication and a little side mounted reset button. +1, tried with 2 different wemos d1 mini (old one and a v3), 2 different types of ld2410 sensors, all sensors report unknown, using Esphome 2023.11.6. Tried compiling the firmware with a macbook, a thinkpad running ubuntu, and even the home assistant green board itself, to no avail. This is a powerful IOT development board, with 16MB flash, external antenna connector and built-in ceramic antenna based on ESP-8266. Same size as D1 mini, but more light. WeMos D1 Mini PRO development board is compatible with Arduino, MicroPython, NodeMCU. And can be programmed in the Arduino IDE. New CP2104 USB-TO-UART IC, built-in ceramic I have a WeMos D1 Mini. Here is the board information: Here is the board information: Arduino: 1.8.9 (Windows Store 1.8.21.0) (Windows 10), Board: "LOLIN(WEMOS) D1 R2 & mini, 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), 4MB (FS:2MB OTA:~1019KB), v2 Lower Memory, Disabled, None, Only Sketch, 115200" Yes you can power the Wemos D1 Mini by supplying 3.3v to the 3v3 pin. Then I dont understand the 3.3v chip thing and why not just use a 3.3v source to power the Wemos and all other to the Wemos connected modules/sensors? Well this one's easy. If it's got to have a usb port on it anyway, might as well use it; and that means stepping 5v down to 3.3. Vay Tiền Nhanh Chỉ Cần Cmnd Nợ Xấu.
