Our development board (the link I sent) is big because it provides provisions for different configurations, it has big ass FTDI chip and external 10/100Base-T port transformers. You could highly optimize the size if you needed, in my opinion. Yes, you can use SPI Ethernet. However, de-soldering RJ4...

You cannot connect Ethernet directly via GPIO. Simply put, the signal on the physical medium (cable) is modulated to be able to be reliably transmitted over longer distances. Therefore transceivers (so called PHY's) at each node need to "understand" themselves. There are multiple standards with mul...

Hi, I have a project where electronics have to be extremely compact. I want to use ESP32 and connect it to an ethernet switch module ( https://shorturl.at/pzHO4 ). I know there are ESP32 variants that have a RJ45 Ethernet port, but I would very much like to avoid it because of how compact the electr...

Hi, I'm sorry if this question was already posted, but I gave it an honest search and didn't find anything. So here goes. I want my ESP32-CAM video feed to be available from any network, not just the local network. I want to be able to see what my ESP32-CAM sees even when I'm away from home, on my s...

Hi, I am designing a small robot with ESP32 at it's core. It will have two modes of operation - automatic (navigating with an ultrasound and other sensors), and a manual mode (controlled remotely via Wi-Fi). For manual control, I want to have a video camera feed from the robot over Wi-Fi. I've seen ...
