Fusion for TIVA v8 Development Board Enables Debugging & Programming over WiFi

Texas Instruments TIVA Arm Cortex-M4 MCU family was first introduced in 2013, I tested a TIVA Launchpad the following years, and since microcontrollers have usually a long life span they are still in use today, and should still be available for many years. I’m writing about this TI MCU family today because MikroElektronika has just announced Fusion for TIVA V8 development board for TI TIVA, Stellaris and MSP432 microcontrollers with plenty of I/Os including some MikroBus expansion slots, as well as support for debugging and programming over WiFi in addition to the usual USB-UART interface. Fusion for TIVA v8 board specifications: MCU – Socket for MikroElektronika MCU CARD Display Interfaces 2x 20-pin TFT display connector 1x 16-pin LCD connector for 2×16 characters LCD displays in 4-bit mode, optional PWM backlight driving feature Programming – On-board CODEGRIP programmer/debugger, JTAG connector for connecting an external programmer/debugger Connectivity – Ethernet port, WiFI in […]

Seeed Studio W600 Certified WiFi Module to Support Arduino, Micropython

Last year, Seeed Studio introduced Air602 WiFi module, a competitor to ESP8266 based on Winner Micro W600 Arm Cortex-M3 microcontroller and selling for $1.90. The module was clearly optimized for cost and size since it offered only a few I/Os, and there was absolutely no mention about FCC or CE certifications. The company has now launched another W600 module, slightly larger to expose more I/Os, and pre-certified to comply with FCC and CE requirements. W600 certified WiFi module is offered standalone, or fitted to “Grove – W600” module for easy connection to Arduino boards. W600 Module Specifications: WiSoC – Winner Micro W600 Arm Cortex-M3 microcontroller with 1MB Flash, RF Transceiver, CMOS PA, BaseBand WiFi Connectivity – 802.11 b/g/n up to 150 Mbps Frequency – 2.4~2.4835 GHz Features – Wi-Fi WMM, WMM-PS, WPA/WPA2, WPS Protocols – TCP, UDP, ICMP, DHCP, DNS, HTTP Access Point and Station modes PCB antenna Expansion – […]

Mediatek MT7629 Dual Core Arm Processor to Power AC1900 Routers

MediaTek is working on a new dual core Cortex A7 processor that supports OpenWrt and targets AC1900 WiFi routers. That’s what I learned from a tweet by WidoraIoT detailing the main features of MediaTek MT7629 SoC as shown in the table below. So basically we have two Arm Cortex-A7 cores clocked @ up to 1.25 GHz, 8MB built-in? flash, HW accelerators and security/crypto engines, multiple Gigabit and Fast Ethernet interfaces, built-in support for 802.11n (WiFi 4) 3×3 MIMO and 802.11ac (WiFi 5) 3×3 MIMO, as well as various interfaces such as PCIe, USB 2.0, USB 3.0, and the usual slower I/Os like I2C, PWM and UART. A web search mostly shows code commits to Linux and U-boot, and we learn a few extra details such as MT7629 shares the same PCIe IP block as MT7622 dual core Cortex-A53 processor. It also reveals a forum post on Widora website with a […]

Intel Launches WiFi 6 AX200 M.2 Wireless Card

WiFi 6 (aka 802.11ax) can deliver up to 10 Gbps in theory, and provides better handling of high density scenario in train stations, conferences, etc… We’ve seen it implemented in some routers and smartphones, but most laptops don’t support the new WiFi standard, so in order to solve this little issue, Intel has now launched AX200 M.2 WiFi 6 card in the M.2 2230 and M.2 1216 form-factors. Intel AX200 works in the 2.4GHz band up to 574 Mbps, and in the 5.0 GHz band up to 2.4 Gbps. The “Cyclone Peak” card works with both USB and PCIe signals, support 2×2 MU-MIMO, and also supports Bluetooth 5.0. Drivers are/will be available for Windows 10 64-bit, Google Chrome OS, and Linux via the “IWLWIFI” driver. Pricing for the cards is said to be $10 and $17, but I could not find it listed anywhere just yet. A few more details […]
