Broadlink MP1 Quad Socket WiFi Power Strip Review and Teardown

Broadlink MP1 is an inexpensive ($20) power strip with four international sockets that can be controlled over WiFi. Since I was interested in finding out how the power strip was designed internally, I asked GearBest whether they could send a sample for evaluation, which they did, and I got it today. So I’ll first check the device, and hardware design, before trying it with the Android app. Broadlink MP1 Unboxing I don’t have much to say about the package, it’s just a bland white box with Broadlink logo. The bottom of the package is useful however, as it contains a sort of user guide in Chinese together with the specifications. I could not find any mentions of CE/FCC/CCC (for WiFi) or UL/TUV (safety) certifications on the package. There’s no more information inside the box, except what looks like a warranty card in Chinese. The power strip itself has four multi-standard […]

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 […]

Broadlink MP1 is a $20 WiFi Power Strip with 4 Independent Sockets

There are plenty of WiFi sockets going around such as Broadlink SP2 or Kankun KK-SP3, but in some cases it might be both more convenient and cheaper to get a WiFi power strip, and Broadlink MP1 offers just that with 4 sockets that can be controlled and programmed (timer) independently, and sold for just $19.88 on Banggood. Broadlink MP1 specifications: Connectivity – 802.11b/g/n WiFi, controllable over 3G/4G with smartphone 4 multi-standard (EU/US/AU, but not UK) sockets Power input – 10A/250V (max) Power output – 10A/250V (max) Rated power – 2000W Total Misc – Power button Dimensions – 254mm x 60mm x 32mm; 50cm sockets spacing; cord Length – 1.5m with AU plug (Adapter provided for other countries) Weight – 450g The power strip can be controlled via Broadlink ihc (Intelligent Hone Control) app available for Android and iOS, which lets you independently manually turn on or off or set timers […]

Realtek RTL8710 Witty-like WiFi IoT Board with micro USB Port Sells for $8 / 35 RMB

Realtek RTL8710 could eventually become a serious competitor to ESP8266, as it’s based on ARM Cortex M3, provides many of the same features, and sells for roughly the same price. While currently software support is still work in progress and community is very small, I’ve recently written a quick start guide using AT commands to control RTL8710 connectivity in station and access point mode, and commands are also available for GPIO, OTA firmware updates, servers… This however requires some soldering and a USB to TTL debug board, and is not quite as convenient as ESP8266 board like NodeMCU. Some RTL8710 and RTL8195 development boards are already available but they cost over $25, but I’ve been informed of a cheap no-name RTL8710 board with a micro USB port for programming and power, and well as headers with GPIOs, UARTs, NFC, and power pins, that looks somewhat similar to ESP8266 Witty board.
