In this lab, you will establish UART based communication channels between the Pi 4 and the HiFive 1 boards. Part 0: Setup the UART connections (for TAs) In this part, we will connect the HiFive1 and the Raspberry Pi 4 boards via two UART channels. (Note that this step will be performed by the TAs.) […]

Thanks to their high accuracy and fast load recovery time, the R&S®NGM200 power supplies are perfect for challenging applications. Their two-quadrant architecture allows them to function both as a source and a sink to simulate batteries and loads. Their short recovery times enable them to handle fast load changes that occur, for example, when mobile communications devices

DIY LoRaWAN gateway with support The Thing Networks and Helium. I was always interested in LoRa, LoRaWAN, SigFox and other low-power and long range wireless technologies. A couple of years ago, I build a single channel LoRaWAN Gateway. Although this was usable for custom projects, it is not a fully compliant LoRaWAN gateway. A fully compliant gateway requires a LoRa
