Innovateking-EU Nodemcu ESP8266 OLED Wifi Module 0.96 inches Display ESP8266 18650 5-12V 500mA Compatible With NodeMCU Arduino

It took a while to find suitable libraries but once found the device works well.Code for a clock is here:/** * The MIT License (MIT) * * Copyright (c) 2016 by Daniel Eichhorn * Copyright (c) 2016 by Fabrice Weinberg * * Permission is hereby granted, free of charge, to any person obtaining a copy * of this software and associated documentation files (the "Software"), to deal * in the Software without restriction, including without limitation the rights * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell * copies of the Software, and to permit persons to whom the Software is * furnished to do so, subject to the following conditions: * * The above copyright notice and this permission notice shall be included in all * copies or substantial portions of the Software. * * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

This Module had a builtin 0.96" Oled, and a battery holder (which can charge an on-board 18650 Lithium battery) This makes it a compact self contained unit, which is very convenient to use. Care has to be taken that the 5v battery charger used does not supply more than 500ma, to prevent damage to the battery, but provided that this caution is observed, there should be no problem.So far I have used it as NTP clock & a WiFi scanner and all has worked well - recommended!

Value good

Small compact but recommended for skilled persons only due to the scripting requirments

Very officiant small circuit board computer

Arrivato prodotto....non si accendeva causa anomalia HW........contattato il venditore,mi e' stato rispedito nuova scheda perfettamente funzionante !Garanzia di ottima professionalita' in caso di anomalie al prodotto.

Verwende die Platine zum testen als Deauther. Die Firmware 2.1 (OLED v2) in der 1MB Version läuft bei mir sehr stabil.Mittlerweile konnte ich bei einigen Geräten die deauth Funktion erfolgreich deaktivieren.Da ich bewusst auf die pigtail variante verzichtet habe ist die Reichweite mit der verlöteten Antenne natürlich nicht gigantisch aber für meine Zwecke ausreichend.

produit arriver avec l'écran casser!!!!!!!!!!

Super Gerät, funktioniert fehlerfrei und ließ sich ohne probleme Programmieren ein Pin für erweiterbare Antenne wäre schön gewesen. Bin Mal gespannt wielange mein OLED Display lebt

Nulla da eccepire sulla scheda, un chipset 8266 completo di display, alloggio per una batteria 18650 (con relativo caricabatterie integrato), interruttore a slitta di accensione e un "joystick / multiswitch" che praticamente da solo è equivalente a 5 pulsanti (alto, basso, sx, dx e centrale). Il connettore microUSB funge da ingresso "dati" (per programmare il chip) ed alimentazione della scheda (e del sistema caricabatteria-batteria).Un mini-laboratorio completo di tutto.... il top sarebbe stato avere un ESP32 (uscito da relativamente poco) invece dell' 8266, ma questi sono dettagli.Il grosso problema è l'imballaggio... schede assemblate del genere (l'unica cosa non saldata sono i pin) non possono essere semplicemente buttate dentro una busta antistatica, e dentro una busta millebolle (stile arduino micro), ma DEVONO avere un'imbottitura che spessora componenti delicati e/o che sbordano (vedi display, interruttore e pulsante/joy).Difatti..... Al primo ordine: il display aveva qualche riga non funzionante (si erano staccati alcuni dei contatti del cavo del display sulla scheda), al secondo ordine lo switch di accensione era arrivato storto (e si era staccato del tutto dopo alcuni utilizzi), al terzo ho trovato direttamente il pulsante/joystick a pezzi dentro la busta antistatica.Tre resi, e cambiato venditore.
