Realtek RTL8710AF (PADI IoT Stamp) vs Espressif ESP8266 (ESP-07) WiFi RF Performance Comparison

After I posted about PADI IoT Stamp IoT kit based on RTL8710AF ARM Cortex M3 WiSoC yesterday, I was soon asked whether I could compare the RF performance against ESP8266 modules like ESP-12. I don’t have any equipment to do this kind of test, except for some simple test like testing range with WiFi Analyzer app, but I remember Pine64 told me they had some comparison data a little while, and accepted to share their results. The test setup is comprised of Litepint IQ2010 multi-communication connectivity test system and PC software, as well as the device under test (DUT) with PADI IoT Stamp (version with u.FL antenna connector) and ESP-07 ESP8266 module as a u.FL connector is required to connect the test system. They’ve tested 802.11b, 802.11g, and 802.11n, but for IoT projects 802.11b is the most important as usually long range is more important than data rate. Test results […]

Samsung Introduces $5 ARTIK 0 and $50 ARTIK 7 Smart IoT Module Families

Samsung unveiled ARTIK 1, 3 and 5 boards for the Internet of Things in 2015, and started to sell them, together with development with WiFi, BLE and Zigbee connectivity earlier this year. The Korean company has now announced two new family with ARTIK 0 modules powered by an ARM Cortex-M MCU and destined to be used in HVAC, lighting, industrial sensors, personal health monitoring and more, as well as ARTIK 7 family powered by an Octa-core Cortex A53 processor, and targeting IoT gateways. ARTIK 0 Family ARTIK 0 family is now comprised for ARTIK 020 with Bluetooth, and ARTIK 030 for applications requiring Thread and/or Zigbee. Beside the different radios, both modules share the same key features: MCU – ARM Cortex-M4 up to 40 MHz with Floating Point Unit, 256KB flash, 32 KB SRAM, advanced hardware cryptographic engine with support for AES-128/-256, ECC, SHA-1, SHA-256, and a Random Number Generator […]

Quirky Linux 8.1 Lightweight Linux Desktop Distribution Released for Raspberry Pi 2 and Pi 3

Barry Kauler, the creator of Puppy Linux, may have retired from maintaining Puppy Linux a few years ago, but he appears to be still active, as he’s just released Quirky Linux 8.1 for Raspberry Pi 2 and Pi 3 boards, a lightweight Linux desktop distribution based on Ubuntu Xenial Xerus 16.04, and including LibreOffice & Inkscape to have the same out of the box experience as Raspbian, but with a 360 MB download size instead of 1.3 GB for Raspbian. A build for ODROID-XU4 development board should also be coming soon. The image has been designed for 8GB micro SD card, and needs to extracted and dumped onto the card with the usual Win32DiskImager or dd tools. There are three mirrors for quirky-pi2-sd-8gb-xerus-8.1.img.xz firmware: iBiblio.org, nluug.nl, and archive.org. You can read the full release notes if you want more details. In case you don’t have a spare micro SD card, […]

Pine64 PADI IoT Stamp WiFi IoT Kit Review – Part 1: Hardware, Debuggers, and Soldering

Back in September, Pine64 unveiled their $2 PADI IoT Stamp based on Realtek RTL8710 ARM Cortex M3 WiFi SoC aiming to compete with Expressif ESP8266 solutions. The company has now sent me their complete kit for review, which beside the module itself includes a breakout board kit, and some hardware debug tools. In the first part of the review, I’ll check out the hardware, and solder the kit. I received a package with four antistatic bags. From top left to bottom right, we have PADI IoT Stamp, JLINK-OB debugger based on an STM32 MCU with some jumper wires (aka Dupont cables) for SWD signals, and a USB cable to your computer in order to flash the firmware or do some bare metal programming, a breakout board kit including two headers, a RED LED, and a resistor, and finally a USB to Serial board based on CH340G with 4 jumper wires […]

ARM Introduces Secure Cortex-M23 and Cortex-M33 ARMv8-M MCU Cores, and Bluetooth 5 Cordio Radio IP for IoT Applications

ARM TechCon 2016 is now taking place in Santa Clara, California, USA, as ARM has made three announcements for the Internet of Things, the focus of SoftBank going forward, with two ARM Cortex-M ARMv8-M cores integrating ARM TrustZone technology, namely Cortex-M23 low power small footprint core, and Cortex-M33 core with processing power similar to Cortex-M3/M4 cores, as well as Cordio Radio IP for Bluetooth 5 and 802.15.4 connectivity. ARM Cortex-M23 ARM Cortex-M23, based on the ARMv8-M baseline architecture, is the smallest and most energy efficient ARM processor with TrustZone security technology,and targets embedded applications requiring both a small footprint, low power, and security. Its power consumption is low enough to be used in batteryless, energy harvesting IoT nodes, and is roughly a third of Cortex-M33 processor size, and offers more than twice its energy efficiency. Cortex-M23 is a two-stage pipelined processor, software compatible with other processors in the Cortex-M family. […]
