Error espcomm upload mem failed

Basic Infos

Hardware

Hardware: ESP-12F Devkit V3 from Banggood.com
Core Version: Not sure

Description

So I just got my ESP-12F today and I can’t seem to get past the flashing of the basic blink script.
I installed the libraries needed but I just can’t seem to make it work.
Getting this over and over again:

}

// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, LOW); // Turn the LED on (Note that LOW is the voltage level
// but actually the LED is on; this is because
// it is active low on the ESP-01)

digitalWrite(LED_BUILTIN, HIGH); // Turn the LED off by making the voltage HIGH
delay(2000); // Wait for two seconds (to demonstrate the active low LED)

I am new to the whole arduino scene. I have connected my wifi module (esp8266 v01) to my arduino Uno like this:

How to connect an ESP8266 to an Arduino UNO

And have downloaded the arduino ide framework so that I may be able to use the arduino IDE as opposed to sending AT commands through the serial monitor.

When trying to upload an example sketch that sends a http request that I found on github, I get the following error:

After looking online and researching, I can see that it has something got to do with flashing the firmware or something. I came across this question:

ESP8266 error: espcomm_upload_mem failed while uploading sketch

and the answer did say that he bought a converter.. what does this mean? Does it mean buying this?:

I really need help, been stuck on this for the past few days now and seriously contemplating whether to get the arduino wifi shield since it comes prebuilt with wifi.. even though it costs quite a lot!

I am having trouble trying to upload any sketch using Arduino IDE to my NodeMCU module, I have IDE version 1.6.10 — I have installed ESP8266 version 2.3.0 in boards manager (I have also tried older versions of both), when trying to upload the Blink sketch I see a blue LED blink twice on my board then I get this error from the arduino IDE:

warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed

— I am using this board from Amazon, nothing is connected besides the microUSB to the USB slot on my laptop:

https://www.amazon.com/HiLetgo-Version- … 010O1G1ES/

— Here are my settings
Board: NodeMCU 1.0 (ESP-12E module) — I also tried various other options
CPU Frequency 80 MHz
Flash Size: 4M (3M SPIFFS)
Upload Speed: 115200 (tried 9600)

— When I connect my serial monitor and press the reset button I see this:
<Garbage> n’t use use rtc mem data
Ai-Thinker Technology Co.,Ltd.
ready

— I tried using ESP8266Flasher with no luck, it gets stuck unable to find my board

— I tried a ton of various MicroUSB cables with no luck, also tried connecting to PC instead of laptop (just in case) — but still getting same error

Any help is greatly appreciated — I pasted in detailed log below in case it helps:
