Innovateking Schematics

[cosmarchy]

Hi,

I bought one of these Innovateking-EU Nodemcu ESP8266 OLED Wifi Module with 0.96" Display and I'm looking to see whether anyone has any schematics for this board?



In order to be able to use this, I'd like to know the type of OLED and how it is connected.  I would also like to know how the 5 way button is connected as well any other I/O.

Does anyone have or know where to find the schematics for this?

Thanks

Hi.
A simple google search of "Innovateking-EU Nodemcu ESP8266 OLED Wifi Module with 0.96" Display" yields this as the first result:
https://www.amazon.co.uk/Innovateking-EU-Nodemcu-ESP8266-Arduino-Compatible/dp/B07JFD21SW

Where if you scroll down, you can read more about the product description:

Product description
Features:
1. One AD inputs.
2. micro USB inputs.
3. one programmable LED (D0).
4. Integrated 18650 charging and discharging system.
5. One switch controls whether the 18650 battery is running or not.
6. SDA OLED and SCL are connected to D1 pin and D2 pin respectively.
7. Five buttons controlled by FLATH, RSET, D5, D6 and D7 respectively.
8. 5 digital contacts can set up read / read / interrupt / pwm / I2C / one-wire supported separately.
9. Operation and NodeMCU sequentially, by adding a programmable LED, you can use GPIO16 to monitor,
Display 8266 status and other features. Integrated OLED and five buttons are more convenient for development.
10. The design concept is based on the open source project NodeMCU,
And the Development Board integrates 18,650 charging and discharging systems with charging and discharging protection.
At the same time, OLED and five directional buttons are integrated to promote development.

Notes:
1. Manual measurement, please allow 1 ~ 5mm error, thanks.
2. This product does not contain 18650 batteries. If the battery is in the wrong direction, the charging chip will be destroyed.
3. I recommend using a 5V 500mA charger, more than 5V 1A there will be a fever,
Does not affect the normal operation, but in the process of charging the chip does not touch or wear,
The measured charge charge will rise by about 60 degrees with a diode chip,
Without heat during normal business hours, be sure to carry around.

Package Including
1 * ESP8266 Module 0.96 inches Display

The OLED is no different from the ones you see in every other hobby project. Only difference is that it's not on a separate board, but integrated into the PCB.
Keywords for google: 0.96'' OLED I2C

If you need to see a schematic from the manufacturer, you can look at some info here:
https://www.winstar.com.tw/products/oled-module/graphic-oled-display/0_96-oled.html

These are usually with SSD1306 chip on flex, so you only need to decide what interface to use.

Anyway, also in that same first link:

Also found some more info about a similar board here so you could check if the connections are the same:
https://www.tindie.com/products/lspoplove/dstike-wifi-deauther-oled-v6/

There are written connections for most things you could be interested.
If you need the schematics you could take a multi meter and beep the connections.

There should be enough info here to get you going.
