    Zdravim a pridavam prispevek ve snaze usetrit spetku casu vsem co by chteli tenhle modulek pouzit s Micropythonem. Deska funguje s celkem v pohode, ale pri flashovani firmware je potreba zvolit mod Dual I/O (parametr esptool -fm dio), tedy: esptool.py --port /dev/ttyUSB0 --baud 460800 write_flash -fm dio --flash_size=detect 0 esp8266-ota-20220618-v1.19.1.bin .... v opacnem pripade nenabehne na UARTu python terminal.

    Zdravím, bastlíři. Nevíte, jestli má tento modul ochranu proti přílišnému vybití baterie a tím pádem jejímu poškození? Díky.

    Zdravím, modul mne zaujal, ale marně hledám informaci jak je na tom se spotřebou při spánku.

    Bohuzel se obavam ze to bude minimalne 1mA, protoze mezi 3,3V VDD a GND je pripojena pres 2K odpor cervena LED, ktera sviti neustale i kdyz je procesor v deep sleep modu (tedy jen LED bude mit odhadem tak 0,8mA).

    Dobrý den, tento údaj bohužel nevíme. Na stránkách výrobce jsme tento údaj nedohledali a osobně jej takto otestován nemáme.
