HydraNFC Shield v2 Delivers Up to 1600 mW with STMicro ST25R3916 NFC Chipset

When Benjamin Vernoux is not working on open-source firmware & tools for AirSpy R0/R2/mini SDR, he spends his time on other projects such as HydraBus STM32 board with NFC support which we covered back in 2014. The HydraNFC Shield that came with the board was based on Texas Instruments TRF7970A NFC chipset with limited features and not compliant with any RF/NFC standard. Benjamin has now launched HydraNFC Shield v2 powered by STMicro ST25R3916 NFC chipset and equipped with a differential antenna. The new version of the shield still works with the original HydraBus board and allows much more output power (1,600mW vs 200 mW) and supports a wider range of NFC features & standards. HydraNFC Shield v2 features and specifications: NFC Chipset – STMicro ST25R3916 high-performance NFC universal device supporting NFC initiator, NFC target, NFC reader and NFC card emulation modes Antenna – Differential antenna with power up to 1600mW […]

NFC Wireless Charging Coming Soon to IoT Devices and Wearables

NFC is better known for contactless payment and transferring contacts, but one interesting feature is the ability to provide power as we’ve recently seen with batteryless NFC powered E-paper displays. The current NFC implementations can only provide a limited amount of power, but the NFC Forum has recently approved the Wireless Charging Specification that enables wireless charging of small, battery-powered consumer and IoT devices with a smartphone or other NFC charging device at a power transfer rate of up to one watt. One watt is not as much as other similar technologies, but NFC wireless charging (NFC WLC) should be quite more cost-effective since device-specific wireless chargers are not needed. Just take a phone or charger with NFC WLC and all compliant devices could be charged that way. The specification is free to download for NFC Forum members but must be purchased by others. There’s still short abstract available: Wireless […]

4.2″ and 7.5″ NFC-powered e-Paper Displays Work without Battery

e-Paper displays have great readability under sunlight, and only consume power when updated. But their refresh rate is limited, and most displays are fairly expensive. One way to reduce the cost is to completely remove the battery from the display, and update it through NFC providing both data and power. I’ve just found out about that possibility through 4.2″ and 7.5″ displays offered by Waveshare. All you need is a compatible NFC smartphone, or the company’s ST25R3911B NFC Board to power the display and transfer your image of choice. This works best for signs you may need to infrequently update such as menus, daily schedules, conference badges, labels, etc… Waveshare NFC-powered e-Paper display key features and specifications: Screens 7.5″ display 800×480 resolution 2-level greyscale 170° viewing angle Refresh Time – 5s + data transfer time 4.2″ display 400×300 resolution 2-level greyscale 170° viewing angle Refresh Time – 4s + data […]

Omnichip Devkit 2 Features Nordic nRF52832 based zGlue ZiP Multichip Module

We first covered zGlue Integration Platform (ZiP) in 2018 when the company introduced its chip-stacking technology with a fitness tracker based on ZGZL1BA ZiP equipped with chips from Dialog Semiconductor, Analog Devices, Macronix, MCube and others. The concept is similar to SiP (System-in-Package), but zGlue claims the costs and lead times are much lower with the technology. Earlier this year, ZiP was back in the news thanks to Antmicro GEM custom RISC-V/Arm ASIC, and today, I was informed about zGlue Omnichip devkit 2 that is equipped with a ZiP of the same name, and that can be used to evaluate the technology. zGlue OmniChip ZiP zGlue OmniChip ZiP is a multichip module with the following ICs (aka Chiplets) and specifications: Nordic Semiconductor nRF52832 Cortex-M4F microcontroller with Bluetooth LE and NFC connectivity Texas Instruments BQ25120AYFPR battery charger, buck regulator Maxim Integrated MAX86140ENP+ optical pulse oximeter Texas Instruments TMP108AIYFFR temperature sensor Bosch […]

What’s the Cheapest Android Phone with NFC Support?

I have an Octopus payment card from Hong Kong using NFC technology, and I’d like to check its status, and if needed top it up to keep it valid. One way to do so is to install the Android app on an NFC enabled smartphone. However, none of my phones, including my current Xiaomi Mi A2 smartphone, support NFC. So I’d decided to look for the cheapest Android phone with NFC support that I could find since that’s the only feature I need, and the app is compatible with Android 4.0 or greater for now. Wileyfox Swift 2X – $75.90 I first went to GearBest to check out for NFC phones, as the cheapest one of the lot is Wileyfox Swift 2X going for $75.90 shipped. The phone runs Android 8.1 on a Snapdragon 430 processor coupled with 3GB RAM and 32GB storage. It is equipped with a 5.2″ Full […]

NXP QN9090 & QN9030 Bluetooth 5.0 SoC’s Come with Optional NFC Tag (NTAG)

NXP has recently announced the availability of its QN9090 and QN9030 Bluetooth 5.0 SoC with optional support for 802.15.4, Multiprotocol RF, and NFC technology. Both devices are powered by an Arm Cortex-M4 core clocked at 48MHz, but differ in terms of on-chip storage and memory with QN9090 equipped with 640KB flash and 152 KB SRAM, against 320KB flash and 88KB SRAM for QN9030. The “T” versions – QN9090T and QN9030T – add NFC integrated on-chip, enabling Bluetooth pairing by tapping a smartphone, tablet or other NFC reader device without the need for a battery-powered NFC tag. NXP QN9090(T) & QN9030(T) Bluetooth 5.0 SoCs Key features and specifications: CPU – Arm Cortex-M4 up to 48MHz Built-in Memory & Storage QN9090(T) – 640 KB flash, 152 KB RAM, 128 KB ROM QN9030(T) – 320 KB Flash, 88 KB RAM, 128 KB ROM External Storage – Quad-SPI for execute in place or data […]
