If battery-operated sensors have to transmit data over a long period of time, LoRa is a suitable transmission method. LoRa uses a type of modulation that enables transmission over long distances with low energy. LoRaWAN, is a network protocol built on top of LoRa that manages communication between LoRa end devices and central servers. It…

After looking at the G1ZH Raspberry Pi HAT, in this article we will look at setting up the required software. This consists of the firmware for the CC2652, Zigbee2MQTT and Mosquitto. Preparation of the SD card We use a current Raspberry Pi OS Lite as the basis, which we copy to an SD card using…

After the boards had been lying around unassembled for a year, it was time to solder the components and run a simple program as a test. The components on the underside could be quickly soldered with a hotplate. Only the flat flex cable and the 2 mm plug for connecting the LEDs had to be…

In recent years, Zigbee has become widely used in home automation. A number of manufacturers offer devices that communicate with each other via Zigbee. A central hub or gateway almost always plays a role here, which takes over the coordination and at the same time enables a connection to the network. For maximum flexibility and…

In my last blog entry we looked at the basic layout of the LC1 LED controller. This post is now about the board design. The goal was to keep the design as compact as possible. The board has two layers and the dimensions are 20 x 70 mm². On the front are the display and…

To start this blog I decided to design an LED light controller. This was planned for lighting during the holidays. The controller should be able to control addressable LEDs. These are usually controlled either with only one data line in which the clock is also encoded or with two separate lines for data and clock.…
