    My first ESP32 Dev board design

    Hi everyone, I am relatively new to designing schematics and PCB's and have only ever done simple circuits up until now. I have tried my hand at designing my very first ESP32 based Dev board. I know that these can be bought for fairly cheap already, but wanted to have a go at actually designing...

    W5500 design issues.

    Hi, I'm trying to create a little ethernet board and I seemingly can't get it to communicate with an ESP32. I'm posting in this thread first as I suspect it's due to the design rather than the ESP32 ethernet library(could be). The design is based on the W5500 as its the chip LCSC has the most...

    What is the output of this VCO?

    I am using ROS-43-119+ from Mini-circuits. I need a VCO that can generate a 40MHz frequency. ROS-43-119+ can generate my required frequency by controlling the tuning voltage. I need sinewave output from the VCO. There is no mention of the output type in the datasheet. So what is the out type...

    Request a review of my first circuit design for a model airplane I'm building

    Hi I'm building a 1/48 scale DC-3 model plane and would like to add some interior LED lights and a pair of micro DC motors. This is my first circuit design so I would greatly appreciate it if someone could review my initial schematic to let me know if it is workable. Obviously once I build the...
