The hardware was assembled by connecting the Arduino UNO R4 WiFi, the PZEM 004T, the current transformer, and the OLED ...
This Arduino library implements a direct Point-to-Point Protocol (PPP) connection between an ESP32 and a host via UART. Unlike IDF PPPoS examples that require a GSM modem, it can establish a direct ...
Volos Projects recently showcased an easy-to-reproduce, inexpensive DIY ESP32-S3 Internet radio based on a Waveshare ESP32-S3-LCD-1.54 development board ...
It’s always nice to simulate a project before soldering a board together. Tools like QUCS run locally and work quite well for ...
The ESP32 does everything a Pi Pico does, but costs less and lasts 100x longer on batteries ...
Makita batteries use a modified 1-Wire protocol at 5V logic levels. The ESP32-C3 operates at 3.3V and cannot reliably communicate with the battery directly. By splitting the system into two MCUs, each ...
