Espressif is Working on a New Wi-Fi and Bluetooth LE Chip with Hardware SSL Support

Espressif came to fame thanks to its low cost ESP8266 WiFi chip which was originally designed for connected lightbulbs, but soon got used in a variety of  applications, and ESP8266 modules must now be the most popular solutions to add WiFi to IoT projects, as long as they are not battery powered. The company has recently announced they were working on a new chip, whose name as yet to be decided, that will support both Wi-Fi and Bluetooth Low Energy. Details are sparse, but we do know the chip will come with 500KB RAM, support hardware SSL and possibly ECDH, deliver 500 DMIPS of performance, and consume 5 uA in deep sleep mode. The company asked for beta testers via their twitter account around 2 weeks ago, so I guess it’s a bit too late to apply. John Lee, working for Espressif, also said the new part should become available […]

Orvibo Wiwo S20 Smart Socket Now Sells for $16

Kankun KK-SP3 used to be the cheapest smart socket on the market at around $20, and it is hackable too, but only available with a Chinese / Australian plug, and for some reasons, many sellers stopped selling the device. Last year, a similar product called Orvibo Wiwo S20 launched with US, UK, EU or AU plug types, but sold for nearly twice as much as KK-SP3 at the time. The good news is that the price has gone down considerably, as it can be purchased for around $16 on GearBest, and it’s available on others for $20 to $26 including on Amazon US, DealExtreme, and GeekBuying. Let’s remind us of the specifications first: Material – ABC 94V-0 (fireproof) Wi-Fi 802.11 b/g/n Security – WEP, WPA-PSK or WPA2-PSK Power Plug – US, Europe, United Kingdom or Australia plug Output Current – 10A Output Power – 2000W max. Voltage Range – 100-240V […]

MXCHIP EMW3165 is an $8 CE/FCC Certified WiFi Module with an STM32F4 Cortex M4 MCU

A few months ago, Seeed Studio started selling MXCHIP EMW3162 Wi-Fi module with a STM32F2 Cortex M3 MCU clocked at 120Mhz for $9.95. It’s more capable than ESP8266 modules but also around 3 times more expensive. The company has now launched another WiFi module called MXCHIP EMW3165 with an STM32F4 Cortex M4 MCU @ 100 MHz, FCC certification, and listed for $7.95. EMW3165 module specifications: MCU – STMicro STM32F411CE ARM Cortex M4 micro-controller @ 100 MHz with 512KB flash, 128KB RAM, DSP, and FPU Storage – 2MB SPI flash Wi-Fi connectivity 802.11b, 802.11g, 802.11n (single stream) WEP, WPA/WPA2 PSK/Enterprise 16.5dBm@11b; 14.5dBm@11g; 13.5dBm@11n Receiver Sensitivity – 87 dBm Station, Soft AP and Wi-Fi direct Support EasyLink On-board PCB antenna (EMW3165-P model) or IPEX connector for external antenna (EMW3165-E model) CE & FCC compliant Peripherals: 22 GPIOs USART, I2C ADC, DAC Timer/PWM JTAG/SWD debug interface Connectors – 1×20 + 1x 21 half-through […]

Freescale Introduces a Coin-sized Single Chip Module (SCM) Based on Freescale i.MX 6Dual

As the Freescale Technology Forum 2015 is taking place in Austin, Texas, the company will announce a few new products over the 4-day conference. After the official launch of Freescale i.MX 7 series processors, Freescale unveiled a new product based on their existing i.MX6 platform with “i.MX 6Dual SCM” (Single Chip Module) that integrate a dual core i.MX 6Dual processor with 1 or 2 GB LPDDR2 (PoP), a 16MB NOR flash and a PMIC in a tiny, coin-sized module. Key feature of SCM-i.MX6D module: Freescale i.MX 6Dual application processor with two ARM Cortex A9 core @ 800 MHz and Vivante GPUs (2D/3D) System Memory – 1 or 2 GB LPDDR2 (PoP configuration) Storage – 16 MB SPI NOR (Micron N25Q128A13) Power Supply – Freescale PMIC PF0100 Dimensions – 17mm x 14mm x 1.7mm There are also 109 discrete components on the module. BSPs for Linux and Android will be provided. […]

Freescale Launches i.MX 7 Series Cortex A7 + Cortex M4 Processors for IoT Applications

Freescale announced plans for i.MX 7 and i.MX 8 processors in 2013, but it’s only in the last few months there have been some patchsets submitted to the ARM Linux Kernel mailing list, and so far all documentation was only available to companies and developers under NDA. Now the company has officially launched i.MX 7 series, and although all documents are not available yet, Freescale has released a factsheet providing an overview about the processors. Freescale i.MX 7 series processors targets applications such as wearables, e-readers, secure point-of-sale equipment, smart home controls, industrial automation products and other IoT solutions. Two processors are currently available: the single core i.MX 7Solo processor, and the dual core i.MX 7Dual processor. Both basically share the same specifications, but beside the extra Cortex A7 core, i.MX 7Dual also adds on extra USB host port, a PCIe interface, an extra Gigabit Ethernet port, and a 4th […]

IoT Wi-Fi Modules Comparison Table – ESP8266 vs CC3000 vs RN131 vs HDG204

We now have several options to add WiFi to IoT / embedded projects at relatively low cost, and ESP8266 based solutions clearly wins on costs, but are there some advantages to other higher priced modules? To help us find out, Mike Barela has put up a comparison table with some Wi-FI modules based on Espressif ESP8266, Texas Instruments CC3000, Microchip RN131, and H&D Wireless HDG204 processors. Note 1 – Also comes in Arduino Shield size with SD card slot for $39.95 Note 2 & 3 – Adafruit and Sparkfun sell tested units with AT Firmware for $6.95. lower prices are available on eBay, but quality may vary. Note 4 – Currents are probably somewhat higher than stock ESP-12 due to onboard LED and regulator. The comparison is not exhaustive, but it still appears to show ESP8266 solutions support most features than pricer competing modules. There are however case where competing […]

Allwinner R8 Module Datasheet and Price. Is the $9 C.H.I.P Computer Selling at a Loss?

Allwinner R8 Cortex A8 processor, very similar to Allwinner A13, but optimized for IoT applications, was first unveiled via the $9 C.H.I.P computer crowdfunding campaign, but at the time we did not have that many technical details. However, Olimex had already made several Allwinner boards in the past, such as A20-OLinuXino-LIME, so they decided to investigate if they too could use Allwinner R8 processor, or rather Allwinner R8 Module (R8M) with R8 SoC, 4/8GB NAND Flash and 512 MB RAM. So they managed to get R8M datasheet, and got quoted $4.8 for Allwinner R8 and $16 for Allwinner R8M with 512 MB RAM and 8GB NAND Flash for 5,000 unit orders. Wait… If R8M module is $16, how can C.H.I.P sell it for $9? One difference is that C.H.I.P module only has 4GB NAND flash, but the module quoted to Olimex appears to come with 8GB flash, but it’s not […]
