First looks at the RAK8213 LTE Cat M1/NB1 IoT Modem

The RakWireless RAK8213 is a Quectel BG96 based 4G LTE Cat M1/Cat NB1/EGPRS modem in a PCI Express MiniCard Form Factor. LTE categories M1/NB1 combined with innovations including Power Saving Mode (PSM) and Extended Discontinuous Reception (eDRX) can rival power consumption and battery life of other IoT Technologies such as LoRa and Sigfox.

EDISON: The 12VDC to 220-380VDC Converter

In the modern home, a surprising number of appliances will operate on “high voltage” DC. More and more appliances (computers, LCD monitors and TVs, compact fluorescent and LED lamps, phone charges etc) incorporate switch mode power supplies. These appliances will rectify the incoming 50/60 Hz mains, convert them to DC
