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 […]

Espressif ESP32 WiFi & Bluetooth SoC is Now Up For Sale for $2.85

Espressif ESP32 is one of the most awaited chip for IoT applications as it combines a dual core processor, WiFi, Bluetooth 4.0, and various I/Os. The good news is that you can now purchase ESP32 for 19 RMB ($2.85) on Taobao, or if you are not based in China, contact Espressif by email at sales [at] espressif.com. Availability is however limited, and the maximum order is now 5 pieces. ESP32 modules and boards, as opposed to just the SoC, are not quite ready right now, but should become available in a few weeks. ESP-WROOM-32 is the ESP32 module developed by Espressif, and NodeMCU is also working on an ESP32 board, so we’ll get more good news very soon. You can also find documentation, hardware and software resources on a Espressif ESP32 page , including a getting started guide, ESP32 SDK, ESP32 reference manual, ESP-WROOM-32 datasheet, and more. If you are […]

Yi Technology Releases an Open API SDK for Yi and Yi 2 4K Action Cameras

Yi Technology, the maker of Yi actions cameras, often wrongly reported as Xiaomi Yi cameras as they are sold in Xiaomi stores, has now released an Open API to allow software and hardware engineers to develop products – such as drones, robots, or 360 deg. video recording setups – using their cameras. YiOpenAPI supports three types of APIs available in Java or Swift languages: Camera control (start/stop recording, capture picture, turn on/off viewfinder, etc…) Camera settings (date/time, video resolution, photo size, video standard, etc…) Camera state (record started/completed, video finder started etc…) There are also some app samples, one of which being YI360Demo available in both binary and source code, and used to control multiple Yi cameras in order to shoot 360 deg. / VR  videos. You can find YiOpenAPI on github, get support on YiOpenAPI Facebook group, and sign-up for news updates on YiOpen.com. Via GeekBuying Blog Jean-Luc Aufranc […]

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 […]

VicoVR is a Wireless 19-Point Full-Motion Tracker for Virtual Reality Working with Android and iOS (Crowdfunding)

There’s a wide a virtual reality solution from cardboard kits that now sells for a couple of dollars to full featured headset with motion tracking selling for several hundred dollars or more. 3DiVi has designed a Kinect like motion tracking device that connects to your Android and iOS smartphone, and is supposed to offer similar tracking capabilities of more expensive head mount displays (HMD) such as HTC VIVE at about half the cost, while also replacing the cables of those kits with wireless connectivity through WiFi and Bluetooth 4.0 LE. The company offer three VicoVR devices part with the following specifications: VicoVR Sensor SoC – Unnamed Samsung Exynos processor Connectivity – Bluetooth 4.0 LE, WiFi 802.11 b/g/n Data stream Bluetooth – User pixel mask @ 30 fps, 3D coordinates up to 19 skeletal joints per user (max 2 users) @ 30 fps, 3D point cloud @ 30 fps up to […]

Wandboard Development Boards Get Android 6.0 Marshmallow Support

Wandboard development boards powered by Freescale i.MX6 Solo, Dual and Quad Cortex A9 processors were released over 3 years ago with Android 4.1 Jelly Bean. Contrary to many other boards that don’t get an updated version, Wandboard boards got support for Android 4.4 Kitkat, Android 5.x Lollipop, and now the community has recently released Android 6.0 Marshmallow. You can try the Android 6.0 SD card image as follows:

Where /dev/sdX is the device for your SD card. If you can remember the first Jellybean release had separate images for each version of the board, but thanks to device tree implementation, a single image is now released with all three versions. The full source code is also available in a 5.0 GB tarball. Since Freescale, now NXP, i.MX6 processors will be available until November 2022, we can most probably expect a few more Android releases for the board. Jean-Luc Aufranc […]
