Nordic Semi nPM1100 PMIC combines battery charger and regulator in tiny WLCSP package

nPM1100

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 […]

Power Profiler Kit II measures power consumption in Nordic Semi based embedded systems

Power Profiler Kit II

If you’re developing battery-powered products it’s important to optimize your application to consume as little power as possible to extend battery life. As we’ve seen with Qoitech Otii Developer Tool, getting the right tool for development can help developers work more efficiently, and save countless man hours. If you’re specifically working on products based on Nordic Semi nRF51, nRF52, nRF53 or nRF91 wireless chips, the company has just announced the Power Profiler Kit II (PPK2) that enables easy and affordable power measurement of average and dynamic power consumption in embedded solutions based on the aforementioned wireless SoC’s/SiP’s. Power Profiler Kit II key features: 200nA to 1A measurement range Resolution varies between 100nA and 1mA depending on the measurement range Instantaneous and average current measurement for all Nordic DKs, in addition to custom HW Ampere meter and source modes Built-in programmable regulator with a 0.8V to 5V output range and up […]

Nordic Semi nRF21540 RF front end module Extends the Range of nRF52/nRF53 Bluetooth SoC’s

A little while ago, we wrote about RFCat N32 board integrating Meshtek-H52 module with nRF52832 2.4GHz multi-protocol SoC and a Skyworks power amplifier increasing power by up to 30 times to extend the wireless range to up to 200 meters. It turns out Nordic Semi outed its own range extender module late last year with nRF21540 RF front end module (FEM) that integrates a power amplifier (PA) and low noise amplifier (LNA) optimized to boost the link budget of the nRF52 and nRF53 multi-protocol wireless SoCs. nRF21540 key features and specifications: Supported wireless standards Bluetooth Low Energy (incl.

Nordic Thingy:91 Cellular IoT Prototyping Platform Comes with 16 Sensors

Nordic Thingy:91

Nordic Semiconductor launched the Nordic Thingy:52 back in mid-2017 in the hopes of bringing app and web developers into the hardware ecosystem as fast and easy as possible.  The Nordic Thingy:52 was a Bluetooth 5 IoT sensor development kit based on the company’s nRF52832 WiSoC. Although the Nordic Thingy:52 kit is still very much available for purchase and support always available, Nordic Semiconductor has gone further launching a new development kit called the Nordic Thingy:91 targeting cellular IoT applications. The Nordic Thingy:91 is a cellular IoT prototyping platform with support for LTE-M, NB-IoT plus GPS option. Even though IoT connectivity standards like LoRaWAN, BLE, WiFi, ZigBee, and others are very much growing and expanding, Nordic Semi is fully backing cellular technology, something that has very much been available and most likely will still keep been available, and the adoption of 5G is another testimony to that. Cellular is here, and […]

$10 Nordic Semi nRF52840 USB Dongle Supports Bluetooth 5, Thread, ZigBee, 802.15.4, ANT and 2.4GHz Proprietary

nRF52840 USB Dongle

Several weeks ago, as I noticed the lack of Bluetooth 5 USB dongles, I found MakerSpot CC2640 Bluetooth 5 USB stick based on Texas Instrument CC2640R2F Arm Cortex-M3 WiSoC. It’s not exactly a consumer products, and instead it’s more like a development kit, but it can still be inserted into the USB port of your computer or development board. Today, I found out Nordic Semi also made their own Bluetooth 5  – or is it Bluetooth 5.0 now, I’m really confused at this point – USB dongle for evaluation & development based on nRF52840 WiSoC. It’s not only for Bluetooth 5 though, as the multi-protocol SoC also supports Bluetooth Low Energy, Bluetooth Mesh, Thread, Zigbee, 802.15.4, ANT(+), and 2.4 GHz proprietary solutions. nRF52840 USB dongle (PCA10059) key features: Wireless Connectivity – Bluetooth 5, Bluetooth Low Energy, Thread, Zigbee, 802.15.4, ANT/ANT+, and 2.4GHz USB – USB 2.0 ports Expansion – 15x […]
