Pine64 Unveils $2 PADI IoT Stamp WiFi IoT Module with FreeRTOS SDK, Upcoming ARM mbed 5.0 Support

Realtek RTL8710 WiFi IoT modules came out as potential competitors to ESP8266 modules last month, with similar features. an ARM Cortex M3, and a pricing as low as $2 in quantities. However, documentation is often in Chinese only, and based on my experience with an RTL8710AF module limited to AT commands set for now. Software and documentation are likely to improve a lot however, as Pine64, the makers of Pine A64 boards, are about to launch their own “PADI IoT Stamp” RTL8710AF module for just $1.99 in any quantities. PADI IoT Stamp specifications: SoC – Realtek RTL8710AF ARM Cortex-M3 @ 83 MHz with 1MB ROM, 512KB RAM, and 1MB flash Connectivity – 802.11 b/g/n WiFi @ 2.4 GHz – 2.5 GHz (2400 MHz – 2483.5 MHz) with PCB antenna; Station / SoftAP / SoftAP + Station modes; Expansion headers – 22 half-holes with Up to 1x SPI @ 41.5 Mbps […]

Zidoo X9S Realtek RTD1295 Android & OpenWrt TV Box System Info & Benchmarks

Zidoo X9S is the first Android TV box based on Realtek RTD1295 quad core Cortex A53 processor that I’ve received for review. So in this post, I’ll show some system information with CPU-Z, and Android & OpenWrt Settings, and run typical Android benchmarks such as Antutu 6.x, Vellamo, and 3Dmark. Zidoo X9S / Realtek RTD1295 Android System Info CPU-Z detects Realtek RTD1295 is a quad core ARM Cortex A53 processor clocked between 600 MHz and 1.4 GHz with an ARM Mali-T820 GPU, and uses an unknown governor… But in adb shell, tje command “cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor” reports an ondemand governor is used. The system runs Android 6.0.1 on top of Linux 4.1.17 (I think it’s the first time I see a Linux 4.x kernel used in a TV box…), and with 1920×1080 resolution. Total RAM is shown to be 1672 MB, most probably because some RAM is reserved for the GPU […]

Development Resources for Realtek “Ameba” RTL8710, RTL8711, and RTL8195 WiFi SoCs

We were made aware of a potential ARM based ESP8266 competitor last week with Realtek RTL8710 WiFi modules selling for about $3.5 shipped per unit, and under $2 per unit for larger orders (100+ pieces). Hardware is good, but for a platform to be successful, or even just useful, you also need software support. So I started doing some research into IoT-Tech BBS and asked ICStation for an “SDK” for the module they sold. I ended up on this forum post providing an “Realtek RTL8710 SDK” via Baidu (password: brwp), which turned out to be about the same as the Google Drive link provided by ICStation, and only contain minimal documents, as well as cracked Windows IAR Embedded Workshop and JLink tools. There are also some more technical details in Chinese only in another forum post, and well as B&T RTL8710 module datasheet (PDF). However, if you don’t read Chinese […]

How to Flash Firmware to Realtek RTD1195 Media Players

Android TV boxes based on Realtek RTD1195 SoC are cheap (about $60), with a relatively slow dual core Cortex A7 processor, but include fast interfaces such as USB 3.0, Gigabit Ethernet, and sometimes SATA, and are said to be very good at playing videos. After several months of development since they’ve first been spotted, RTD1195 media player are finally shipping. One of the models is M-195, which had its firmware recently released, and can be downloaded from copy.com, filefactory, mediafire, or solidfiles servers. This firmware is based on Android KitKat 4.4.2, with build number rtk-phonenix-eng 4.4 krt160 eng.ton.20141024.094201. Firmware update is pretty easy, and is operating system agnostic, since all you need to do is to basically copy the firmware file to a USB flash drive. A PC is not even necessary, as you can download the file and extract it directly from the mini PC itself. The same procedure […]

AsiaRF AWM002 Wi-Fi Module and a Tiny IoT Server Kit Get Crowdfunded for $15 and Up

VoCore Wi-Fi module selling for $15 to $20, and it’s corresponding VoCore Dock with Ethernet has been quite popular, and at the time of writing, the project has already received $40,000 in funding with 50 more days to go. But if you’d rather get something for the same price, a few months early, and an already FCC/CE certified and proven module and tiny IoT server, AsiaRF has also launched a crowdfunding campaign for their AWM002 Wi-Fi module running OpenWRT on the same Ralink RT5350 found on the VoCore. as well as AWM002 Tiny Kit which adds Ethernet and USB, and a larger board with easier access to all ports and I/Os. As a reminder, let’s go through AWM002 specifications again: SoC – Mediatek/Ralink RT5350 MIPS 74KEc core @ 360 MHz dual band 802.11n Wi-Fi with data Rate up to 150Mbps, hardware NAT, QoS, TCP/UDP/IP checksum offloading. System Memory – 32 MB Storage […]

$15 Open Source Hardware VoCore Wi-Fi Module Runs OpenWRT (Crowdfunding)

There are already low cost Wi-Fi modules that can be used for the Internet of Things such as AsiaRF AWM002 and Hi-Link HLK-RM04. However, AsiaRF mainly caters to companies, and the Hi-Link module has a limited memory (16MB), which may or may not be an issue depending on your application. VoCore Wi-Fi module could prove to be an interesting option as it is the same $15 to $20 price range, runs OpenWRT with 32 MB RAM, will be open source hardware, and provides up to 20 GPIOs in a tiny (25x25mm) form factor. VoCore Wi-Fi module specifications: SoC – Ralink/Mediatek RT5350 MIPS processor @ 360MHz with dual band 802.11n Wi-Fi with data Rate up to 150Mbps System Memory – 32 MB RAM Storage – 8MB SPI Flash (for firmware) / 16 MB on limited edition Available Signals (Via through holes): 10/100M Ethernet USB UART, I2C, SPI I2S, PCM JTAG Over 20 […]
