Golioth IoT development platform offers Zephyr SDK, support for nRF9160, ESP32, and over 100 other platforms
There are already plenty of IoT development platforms, but here’s another one with Golioth that relies on a Zephyr SDK, “first-tier” support for Nordic Semiconductor nRF9160 (cellular) and Espressif Systems ESP32-C3 (WiFi), as well as a QEMU-based simulator for easy testing. The use of an open-source Zephyr SDK even enables them to support over 100+ hardware components, and the company, also called Golioth, says their platform scales from one device for evaluation to one million devices during deployment, thanks notably to a free Dev Tier account to get started at no cost. Some of the other highlights of Golioth include: “Secure by Default” communication over efficient protocols like CoAP and soon MQTT Access to Device Services like Software updates that include secure boot and firmware management Real-time NoSQL database (LightDB) that can be useful for creating Digital Twins and synchronization Time-series database (LightDB Stream) for storing and querying sensor data […]

Nordic Semi nPM1100 PMIC combines battery charger and regulator in tiny WLCSP package
Nordic Semi is well-known for its 2.4GHz multi-protocol chips such as nRF52840 or nRF52832 that are typically found in battery-powered devices such as smartwatches with Bluetooth connectivity. But once rechargeable batteries are involved that means a charging circuit is needed, and for instance, PineTime nRF52832 based watch relies on SGMicro SGM40561 Li-Ion battery charger and SGM2036 low-power regulator. So Nordic Semi has decided to get involved in the power management business and launched its first PMIC with nPM1100 combining a USB-compatible Li-ion/Li-Po battery charger and an efficient DC/DC buck regulator in a single, compact WLCSP package. Nordic Semi nPM1100 PMIC key features and specifications: 400 mA battery charger USB compatible input regulator Up to 150 mA of regulated voltage output at 1.8, 2.1, 2.7, or 3.0 V Overvoltage protection Ship mode disables power output Low quiescent currents Drivers for charge and error LEDs Supports Lithium-Ion and LiPo batteries with a […]
