Custom ESP32-S3 development board — professionally manufactured by JLCPCB. A far cry from where it all started. It Started in a School Science Lab — Around 1998 Most people who get into electronics start with a kit, a tutorial, maybe a breadboard and some LEDs. I started by sneaking ferric chloride out of a school science lab to etch my first PCB. That was around 1998. I was living in the Maldives — a small island nation in the Indian Ocean — where there was no electronics supply chain, no maker community, no local PCB fab. Just a chemistry cabinet at school, a copper-clad board from somewhere, and a lot of curiosity. This post is about what the next 25+ years of PCB prototyping looked like from there. The early wins with proper chemicals, the years of improvisation when those chemicals disappeared, the real injuries, the failed boards, and finally — the moment JLCPCB changed ever...
Its been a while i have this LCD and today i thought of connecting the LCD display to Arduino. Unfortunately i could not found any pin outs of this from any where and from the manufacture. Actually this is very old model which i got from old FAX machine and this display is a very cheap from online sources.
Clover Display M302 PCB Ver 1.0 (16x2) which has 10 pin flat cable. After researching for a while from the internet i have seen in many forums people are asking for help on how to connect it and what is the pin configurations? so i thought of helping them as well as my self at the same time.
After going through some of my old collections of Russian data of displays and things i found a basic diagram of how 10 pin LCD display configuration.
PIN1 - VSS
PIN2 - VDD
PIN3 - CONTRAST
PIN4 - RS
PIN5 - R/W
PIN6 - ENABLE
PIN7 - DB4
PIN8 - DB5
PIN9 - DB6
PIN10 - DB7
I tried these configurations and wired up to the arduino with the LCD sketch and it worked on the first try. Adjusting the contrast and it was perfect. I hope this will help to those who looking for a solution.
