Low Power TinyPICO ESP32 Board Ships with Micropython (Crowdfunding)

There are so many ESP32 boards available now, so why bother with another ones. Some of the key selling points of TinyPICO are that it is really small at 32 x 18 mm, it’s easy to use out of the box with MicroPython firmware pre-loaded, and supports LiPo batteries with an optimized power path for low-power battery usage. The developer, named Unexpected Maker, also provides various shields for TinyPICO adding a display, sensors, an audio amplifier, an RTC, Grove headers, and more. TinyPICO board specifications: System-in-Package – Espressif Systems ESP32-PICO-D4 SiP with ESP32 dual-core processor operating at 240 MHz, 4 MB SPI flash External System Memory – 4 MB PSRAM Connectivity – 2.4 GHz WiFi 4 802.11b/g/n, Bluetooth 4.2 LE, 3D antenna Expansion – 14x GPIO broken out to standard pitch headers Debugging / Programming – USB + serial/UART for programming Misc – Power (red) & charge (orange) LED’s, APA102 RGB LED Power Supply 5V via micro USB port 700 …

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. Pricing currently ranges from 15.96 Euros (Net) to 29.40 Euros (Net), but price may …

Seeed Studio W600 Certified WiFi Module to Support Arduino, Micropython

Last year, Seeed Studio introduced Air602 WiFi module, a competitor to ESP8266 based on Winner Micro W600 Arm Cortex-M3 microcontroller and selling for $1.90. The module was clearly optimized for cost and size since it offered only a few I/Os, and there was absolutely no mention about FCC or CE certifications. The company has now launched another W600 module, slightly larger to expose more I/Os, and pre-certified to comply with FCC and CE requirements. W600 certified WiFi module is offered standalone, or fitted to “Grove – W600” module for easy connection to Arduino boards. W600 Module Specifications: WiSoC – Winner Micro W600 Arm Cortex-M3 microcontroller with 1MB Flash, RF Transceiver, CMOS PA, BaseBand WiFi Connectivity – 802.11 b/g/n up to 150 Mbps Frequency – 2.4~2.4835 GHz Features – Wi-Fi WMM, WMM-PS, WPA/WPA2, WPS Protocols – TCP, UDP, ICMP, DHCP, DNS, HTTP Access Point and Station modes PCB antenna Expansion – 25x castellated holes with 2x UART, 2x SPI, up to …

Eclipse IoT Survey Report Reveals Arm & Linux Dominate, Security Concerns

The Eclipse IoT Working Group has just released a report asking the global IoT developer community to share their perceptions, requirements, and priorities. And with over 1,700 individuals taking the survey between February and March 2019, the key findings are interesting: IoT drives real-world, commercial outcomes today. 65% of respondents are currently working on IoT projects professionally or will be in the next 18 months. IoT developers mostly use C, C++, Java, JavaScript, and Python AWS, Azure, and GCP are the leading IoT cloud platforms Top three industry focus areas remain the same as last year: IoT Platforms, Home Automation, and Industrial Automation / IIoT. MQTT remains the dominant IoT communication protocol leveraged by developers The Eclipse Desktop IDE is the leading IDE for building IoT applications The last point may be slightly biased because the survey was done by the Eclipse IoT Working Group, so most respondents were already familiar with the Eclipse IDE. Security concerns dropped slightly compared …

FreeRTOS Kernel Now Supports RISC-V Architecture

FreeRTOS is one of the most popular operating systems found in embedded systems, and RISC-V open architecture is getting more and more traction, so it should come as no surprise that Amazon has now added RISC-V to their recently acquired FreeRTOS kernel. Jeff Barr, Chief Evangelist for AWS, explains both 32-bit and 64-bit RISC-V cores are supported, and several RISC-V boards are already supported out of the box: The kernel supports the RISC-V I profile (RV32I and RV64I) and can be extended to support any RISC-V microcontroller. It includes preconfigured examples for the OpenISA VEGAboard, QEMU emulator for SiFive’s HiFive board, and Antmicro’s Renode emulator for the Microchip M2GL025 Creative Board. There’s no a lot of information on Amazon announcement post, but FreeRTOS website has plenty of resources to help you get started with RISC-V. The page also lists some of the key features of the RISC-V port: Supports machine mode integer execution on 32-bit RISC-V cores only, but is …

NXP i.MX 8M Nano is a Power-optimized Arm Cortex-A53/M7 Processor

NXP introduced their first 14nm i.MX processor at Embedded World 2018 last year with i.MX 8 Mini processor equipped with up to four Cortex A53 cores clocked at 2.0 GHz and one real-time Cortex-M4 cores clocked at 400+ MHz, and optional 1080p video output and decoding/encoding. The company has now added another 14nm member to their i.MX 8M family with NXP i.MX 8M Nano family also featuring four Cortex-A53 cores at up to 1.5 GHz, but replacing the Cortex-M4 by a more powerful Cortex-M7 core clocked at up to 600 MHz. The processor is also power-optimized for less than 2W total dynamic power (TDP) and sub-watt in many IoT edge applications. NXP i.MX 8M Nano key features and specifications: Application cores – One to four Arm Cortex-A53 cores up to 1.5 GHz per core; 32KB L1-I Cache/ 32 KB L1-D Cache; 512 KB L2 Cache Real-time core – Arm Cortex-M7 at speeds of up to 600 MHz; 16 KB L1-I …
