    Hi Jin, I spotted your profile with your ESP32/GSM project. I want to design a single channel LoRa gateway for my sensors. It should be able to collect data from LoRa devices (868Mhz) and send it to the The Thing Network or custom IoT backend via WiFi (ESP32), GSM (GSM/LTE module) or satellite (Iridium service). There is already an existing Arduino based firmware witch do that via WiFi, but I n...

    I am looking for someone to design a simple high side PWM circuit. This will be running at 12-15vdc and could theoretically have a load of 15A max. It can't be low side because the negative terminal of my PWM controlled device is grounded to the frame. I prefer Kicad, or Fritzing as those two are easiest for me to customize my board layout in. If you can make the circuit entirely using digike...
