GAPPoc AI development boards based on the GAP8 RISC-V Chip

GreenWaves has developed a development board based on the GAP8 chip which can be evaluated from a GAPuino board, a generic board that can run off a low power external power source or USB and is compatible with the Arduino ecosystem. Recently the company moved beyond the generic board to the GAPPoc, platform which stands for GAP8 Proof of Concept. The GAPPoc is focused on a class of applications which can be embedded on a single board and able to carry hardware such as crystal or external memory, sensors, a radio fit, and a battery. The board will be geared towards a set of low power functions for a particular class of applications. This is a family of boards designed to increase the range of abilities in edge Artificial Intelligence. At this time there is only a single board with a platform to enhance AI, targeting Computer Vision in the […]

Raspberry Pi 4 Features Broadcom BCM2711 Processor, Up to 4GB RAM

Long expected, the Raspberry Pi 4 model B has finally launched, and it should not disappoint with a much more powerful Broadcom BCM2711 quad-core Cortex-A72 processor clocked at up to 1.5 GHz, 1 to 4GB LPDDR4, 4K H.265 video decoding and output support, a proper Gigabit Ethernet port, as well as USB 3.0 and 2.0 ports. Raspberry Pi 4 comes with all those extra features, but the form factor remains the same, and importantly the price is still $35 for the version with 1GB RAM, making Raspberry Pi alternatives suddenly much less interesting. Raspberry Pi 4 specifications: SoC – Broadcom BCM2711 quad-core Cortex-A72 (ARMv8) @ 1.5GHz with VideoCore VI GPU supporting OpenGL ES 3.0 graphics System Memory – 1GB, 2GB or 4GB LPDDR4 Storage – microSD card slot Video Output & Display I/F 2x micro HDMI ports up to 4Kp60 (Currently 1080p60 max. in dual-display configuration, although 2x 4Kp30 is […]

Silicon Labs Demonstrates Bluetooth 5.1 Location Technology (Video)

Recently there are been advancements related to precise indoor positioning with the announcement for Bluetooth 5.1 and 802.15.4z. Both can provide 1 to 10 centimeters accuracy with minimal lag, and Bluetooth 5.1 achieves this through Angle of Arrival (AoA) and Angle of Departure (AoD) features and an antenna array. I had never seen the new feature in action, but Silicon Labs recently demonstrated Bluetooth 5.1 location technology at Arrow IoT summit with a DMX-512 connected light following a person carrying a Bluetooth 5.1 tag. It looks fairly accurate, and it does not have a 3-6 seconds lag like previous solutions based on earlier versions of Bluetooth? So what does one need to enable Bluetooth 5.1 location finding? First, we’ll need a Bluetooth 5.1 base station with an antenna array, The one used above includes a 16 antenna array (4×4 grid) used to calculated angles of departure and arrival and ultimately […]

Aconno Bluetooth Beacons Come with Various Sensors, Nordic Semi nRF52 BLE SoC

We first covered products from Aconno is 2017 with their Bluetooth LE development board powered by the company’s ACN52832 BLE module based on Nordic Semi nRF52832 ARM Cortex-M4 multi-procotol wireless SoC. Since then they’ve launched several small Bluetooth beacon modules based on ACN52832, and the company has what they call a presale promotion until May 21st, but it looks really like a group buying event for their existing BLE modules where the price goes down as more people purchase modules. Six Bluetooth modules are offered: acnSENSA multisensor Bluetooth tag with temperature, light, humidity, barometer, accelerometer, magnetometer, gyroscope acnBEACON programmable Bluetooth tag acnACT BLE beacon with button and RGD LED, magnetometer, phototransistor acnNFC programmable Bluetooth tag with NFC tag emulator acnRANGE distance measuring beacon with time-of-flight sensor acnFIND Bluetooth smart tag with LED, sound and accelerometer All modules come with a replaceable CR2450 battery, and IP65 enclosure.

MT3620 Mini Dev Board is a Cheaper Microsoft Azure Sphere Board

Announced nearly one year ago, Microsoft Azure Sphere is an ecosystem comprised of Azure MCUs with Microsoft Pluton Security System, Linux based Azure Sphere OS, and a secure cloud service called Azure Sphere Security Service. The first official Azure development board – MT3620 Development Board for Azure Sphere – was launched last year for $84.95. The kit may not have attracted a large number of developers, so there’s now a cheaper version – MT3620 Mini Dev board – going for $34.90 on Seeed Studio. Note that’s a pre-order and shipping is scheduled for May 13, 2019.
