Plain and Simple LoraWan (LowPower) Library for STM32
It took a lot of time for trying, testing, debugging, but finally I managed to create a plain and simple LoraWan LowPower Library for STM32. Especially for the STM32L051C8T6 microcontroller …
Real life Low Power measurements STM32L
Thanks to Kim, who attended me on the Nordic Power Profiler Kit II, my tests on power measurements got a lot easier. Now I have a little post about power …
Li-Ion/Li-Po Power Supply controller
For another project I wanted to use a Li-Ion or Li-Po battery charger and controller that gave a 3V3 and 5V output. The power demands were not high. After searching …
Soladin600 PV monitor
In April this year (2020) a friend of mine asked if I could make a device that monitors his more than 10 years old Solar System (Photo Voltaic). The power …
Considerations of Power consumption on LoRa Nodes
After designing and building 2 types of Low Power LoRa nodes I did some measurements and calculations. I hope it will benefit your considerations how to use and program Low …
Interfacing Dutch Smart Meter
Due to the small form factor, low power consumption I’ve used the Orange Pi Zero LTS to make an interface to the Dutch Smart Meter (DSMR). In earlier post I …
Raspberry Pi – Smart Powermeter P1 Interface
In the netherlands we use smart power meters in our homes. Every smart powermeter has a standardized interface. You can see the electrical interface here: When the Data_Request line is …
