https://www.electronics-lab.com/meet-esp32-c3-board-on-top-of-a-rechargeable-16340-battery/
What can be better than ESP8266 and ESP32? Maybe a battery-powered ESP32-C3 board designed to provide lower power consumption. LILYGO® has just launched an ESP32-C3 board with a rechargeable 16340 battery holder. The new board, aptly named LILYGO TTGO T-OI PLUS consumes lesser power as its SoC single-core RISC-V processor uses 5uA and 130uA in deep and light […]
Convert your Raspberry Pi in an Open Source tablet with the RasPad 3
https://www.electronics-lab.com/convert-your-raspberry-pi-in-an-open-source-tablet-with-the-raspad-3/
Introduction Single-board computers based on the Raspberry Pi are powerful, low-cost, and compact. This makes them excellent for small tasks that require a real computer rather than a low-level microcontroller. However, they have a minor downside in that, they are compact but not easily portable when given as a simple circuit board. SunFounder offers a […]
