Allwinner A133 tablet processor pairs with XR829 or AW859A WiFi & Bluetooth chip

Allwinner A133 Tablet Block Diagram

Last year, Allwinner published an updated roadmap for tablet processors that included A100, A200, and A300 SoC’s. None of those have been launched yet, but I’ve just noticed the Allwinner A133 quad-core Cortex-A53 processor showed up on the company’s website. That’s yet another entry-level processor coupled with a PowerVR GE8300 GPU, but you’d get support for Android 10, instead of the older Android 7.1/8.1 SDK provided for the earlier Allwinner A-series tablet processors. This time around, the company also pairs A133 processor with its own wireless chips, either XR829 WiFI 4 and Bluetooth 4.2 chip, or AW859A dual-band 802.11ac WiFi 5 and Bluetooth 5 chip. Allwinner A133 specifications: CPU – Quad-core Arm Cortex-A53 @ 1.6GHz with 32KB L1 I-cache + 32KB L1 D-cache per core, 512KB L2 cache, and CoolFlex power management architecture GPU – Imagination PowerVR GE8300 with support for OpenGL ES3.2, Vulkan 1.1, OpenCL 1.2 Memory I/F – […]

The quest for a blob-free WiFi & Bluetooth stack for BL602 WiSoC

PineCone BL602 Board

I thought I was done writing about Bouffalo Lab BL602 WiFI & Bluetooth RISC-V SoC for a while after first covering the chip itself, and then an inexpensive BL602 development board this weekend. But the BL602 SDK has shown up in various Github repositories, including Bouffalo Lab’s own bl_iot_sdk repository, and as more people are looking into it, there’s now an effort to develop a fully open-source blob-free WiFi & Bluetooth stack for BL602, and other Bouffalo Lab WiFi and/or Bluetooth wireless chips. Last day we communicate with Bouffalolab, finally they release the SDK of BL602 (RV32 chip of wifi+bt), all code is open, except libblecontroller.a, libatcmd.a, libbl602_wifi.a (while they have all symbol inside)https://t.co/giHsQ4ezXxwe have a fork too https://t.co/FiaAIxLBc8 — Sipeed (@SipeedIO) October 27, 2020 First, Sipeed says the code is mostly open-source except for three libraries: ibblecontroller.a, libatcmd.a, libbl602_wifi.a, all of which are un-obfuscated, and easy to disassemble. Then […]

BL602 IoT SDK and $5 DT-BL10 WiFi & BLE RISC-V development board

DT-BL10 BL602 Development Board

Yesterday, we wrote about Bouffalo BL602 32-bit RISC-V WiFI and Bluetooth LE wireless SoC that should eventually compete with ESP8266 in terms of price but with more features, higher performance. and more resources like memory and storage. At the time, I noted I could not find any tools for the processor, but I was informed a BL602 SDK (Doiting_BL) and documentation had already been released on Github. The basic readme and a user manual are already available in English, but the main documentation is still in Chinese with various examples to configure GPIO, YART, WiFi, and Bluetooth. You’ll find the documentation in Github, as I could not find a website yet:

Go to Doiting_BL/docs/html folder and then open index.html in your browser to access the documentation. The SDK works both in Windows and Linux and relies on either Eclipse & OpenOCD or Freedom Studio & OpenOCD. A graphical software […]

BL602/BL604 RISC-V WiFi & Bluetooth 5.0 LE SoC will sell at ESP8266 price point

BL602 BL604 RISC-V WiFI & Bluetooth SoC

Hisilicon Hi3861 may be the first RISC-V WIFI SoC we’ve reported on, but due to political uncertainties and security concerns, supplies may not be available outside of China. So alternatives are welcomed, and Nanjing-based Bouffalo Lab (not a typo, 博流智能科技 in Chinese) has recently introduced BL602 and BL604 32-bit RISC-V WiFi and Bluetooth LE SoC for low-power IoT applications that are supposed to compete against ESP8266 in terms of price but with higher performance and additional features. The BL602 will also be integrated into an upcoming Sipeed Longan-series board, and potentially a new IoT board from Pine64. BL602 / BL604 key features & specifications: MCU subsystem – 32-bit RISC-V CPU with FPU with dynamic frequency from 1MHz to 192MHz, L1 cache Memory – 276KB SRAM on-chip Storage 128KB ROM, 1Kb eFuse, and optional Embedded Flash on-chip XIP QSPI flash support  Wireless Wi-Fi 4 – 802.11 b/g/n @ 2.4 GHz Bluetooth […]

UL-Certified TP-Link Kasa Smart Plug with Dual Outlet Sells for $19.99 (Promo)

UL-Certified Smart Plug TP-Link Kasa

WiFi smart sockets to control home appliances have been around for a few years, and one of my favorite companies is Sonoff as they offer a variety of affordable smart plugs pre-loaded with eWelink firmware and compatible with open-source firmware like Tasmota and ESPurna. The company is also attentive to safety. communicate issues with customers, and recently wrote a post entitled “Safety is our responsibility” where they detail all steps taken to make sure their mains connected device sare safe to use. Sadly that does not include safety certifications like UL/ETL, or TUV which may have implications for your home insurance depending on where you live, and for peace of mind, it’s always good to have a third verify your design for safety. Which brings me to the main point of this point, as a UL-certified dual-outlet smart socket, namely TP-Link Kasa Smart Plug, is currently on sale for $19.99 […]
