Implement a Linux gateway that reads serial port ( USB, serial , bluetooth) commands and transfers to MQTT host. MQTT without ethernet or Wifi on a low cost micocontroller. Don't develop a serial command interface , just use MQTT UI's and features.

This project contains various GNAT Ada Run Time Systems (RTSs) based on FreeRTOS for MCUs: the Arduino Due, the STM32F4-series evaluation boards from STMicroelectronics and the BBC micro:bit (v1); working on Espressif ESP32-H2 and RaspberryPi RP2350 (risc-v core)

This library for MicroPython makes it easy to leverage the complex functionality of the Texas Instruments INA219 sensor to measure voltage, current and power.

This MicroPython library provides a framework for interacting with HD44780-based LCD displays through a PCF8574 I/O expander. It offers a high-level API for LCD control, including text display, cursor manipulation, and backlight settings, while also providing lower-level access to the GPIO operations on the PCF8574.
