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...
Today i started to test some RF Modules that i have got from a friend. RF( Radio Frequency) Module that i have is a Transmitter and a Receiver, which communicate at a frequency of 433.92 MHz.
These modules are awesome because i have to feed serial data to it and it transmit using ASK or AM Modulation method. Still i am doing tests on the circuits and for the time being, the data transfered was successful. I will update you all once i complete the tests.
