Banggood

these are great for powering little devices that you would like to have remote data access to. thoroughly recommend. run mine on 1 3.7 v battery. (shown in pics as red 26650, robots’ top load). love em

Good ESP8266 variant with low standby current LDO and small footprint ideal for my humidity/temperature sensors.

Güzel mikrodenetleyici. Wifi üzerinden haberleşme yapılacak projeler için küçük ve kullanışlı. Uygun fiyat.

Fantastic little remote sensor over wifi. Easy to flash with Tasmotiser to make management over Domoticz possible.

Product OK. Tested quickly and flashing without problem with esptool.

the modules were not programmed with micropython as described. Erasing and programming with micropython using esptool as usual was not successful. Module message after reset said "cserr". Same effect with all 5 modules i received.

Excelente para proyectos IoT, se programa con microPython, fácil de utilizar

Arrived in Serbia after 18 days. Tested, works fine. Wish it were packed better since it is sensitive electronics.

very happy with this product. i bought a lot of these and always satisfied. easy to use, small and efficient.

Everything is ok
