Ever since I got into electronics and embedded systems during college, Iโve worked with boards like Arduino, ESP32 dev kits, and Teensy. But deep down, I always had a dream โ ๐ ๐๐ฉ๐ข๐ต ๐ช๐ง ๐ ๐ค๐ฐ๐ถ๐ญ๐ฅ ๐ฐ๐ฏ๐ฆ ๐ฅ๐ข๐บ ๐ฅ๐ฆ๐ด๐ช๐จ๐ฏ ๐ข ๐ฅ๐ฆ๐ท๐ฆ๐ญ๐ฐ๐ฑ๐ฎ๐ฆ๐ฏ๐ต ๐ฃ๐ฐ๐ข๐ณ๐ฅ ๐ฐ๐ง ๐ฎ๐บ ๐ฐ๐ธ๐ฏ ๐ง๐ณ๐ฐ๐ฎ ๐ด๐ค๐ณ๐ข๐ต๐ค๐ฉ?
At the beginning of this year, I finally turned that dream into reality. ๐ง๐โ๏ธ
I designed a custom board using the ESP32-S3 module as the core. I made sure to expose all the GPIO pins and added dedicated I2C and SPI connectors for seamless integration with sensors and peripherals.
I created the schematic and PCB layout using ๐๐๐ฌ๐ฒ๐๐๐, and got the PCBs manufactured through Robu.in (๐๐ฐ๐ต ๐๐ฑ๐ฐ๐ฏ๐ด๐ฐ๐ณ๐ฆ๐ฅ). Once the boards arrived, I carefully soldered the components myself, plugged it in, and uploaded code using the ๐๐ซ๐๐ฎ๐ข๐ง๐จ ๐๐๐โ and to my surprise (and relief), it worked flawlessly on the very first attempt! ๐
This project has been an incredibly rewarding experience that brought together hardware design, hands-on assembly, and firmware testing. While it may be a small step technically, it represents a significant milestone in my growth as an engineer and maker. ๐ก๐ฅ
For anyone considering building their own development board โ I wholeheartedly encourage you to try it. The learning curve is absolutely worth it, and the satisfaction of bringing your own design to life is unmatched.
