STM32WB5MMG Wireless Module simplifies Bluetooth LE, Zigbee, OpenThread connectivity

STM32WB5MMG Wireless Module

The STM32WB5MMG (STM32) is a wireless microcontroller module by STMicroelectronics. It is a compact ultra-low-power module that allows customers to design 2-layer PCBs and integrates everything up to the antenna, including an IPD (integrated passive device) for reliable antenna matching in order to reduce the overall costs. The STM32 wireless module is compatible with BLE (Bluetooth Low Energy) 5.0, OpenThread, Zigbee 3.0, dynamic and static concurrent modes, and 802.15.4 proprietary protocols. It also supports simultaneous dual-protocol mode that allows IEEE 802.15.4 radio-based protocols like Zigbee 3.0 and OpenThread for direct connection with any BLE device. Overview of STM32 Wireless Module The STM32 wireless module is a SiP-LGA86 package (System in Package Land Grid Array)  with various external components including:  STMicro STM32WB55 Cortex-M4/M0+ wireless MCU LSE crystal  HSE crystal Passive components for SMPS  Antenna matching and antenna  IPD for RF matching and harmonics rejection Key Features of STM32 Wireless Module Dedicated […]

Linux 5.10 LTS release – Main changes, Arm, MIPS and RISC-V architectures

Linux 5.10 release

Linus Torvalds has just released Linux 5.10: Ok, here it is – 5.10 is tagged and pushed out. I pretty much always wish that the last week was even calmer than it was, and that’s true here too. There’s a fair amount of fixes in here, including a few last-minute reverts for things that didn’t get fixed, but nothing makes me go “we need another week”. Things look fairly normal. It’s mostly drivers – as it should be – with a smattering of fixes all over: networking, architectures, filesystems, tooling.. The shortlog is appended, and scanning it gives a good idea of what kind of things are there. Nothing that looks scary: most of the patches are very small, and the biggest one is fixing pin mapping definitions for a pincontrol driver. This also obviously means that the merge window for 5.11 will start tomorrow. I already have a couple […]

Ollie USB board exposes isolated UART, CAN, USB, RS485 & RS232 interfaces (crowdfunding)

Ollie USB board

Just like months, we wrote about Tigard open-source USB FT2232H board for hardware hacking with easy access to OpenOCD, JTAG, Cortex, flashrom interfaces used to debug/flash boards, extra I/Os with UART, SPI, and I2C, as well as a header to connect a logic analyzer and observe signals. If the board does not exactly match your requirements, Ollie USB board might, also it may not serve exactly the same purpose(s). The board acts as a USB bridge to isolated UART (x2), CAN, USB, RS485, and RS232 interfaces. Ollie specifications: MCU – STMicro STM32F042 Arm Cortex-M0 microcontroller with CAN interface Host interface – Micro USB port Isolated interfaces (all with ESD protection) 2x UART ports up to 12 Mbps with 1.8/3.3/5 V voltage levels (set by slide switch) CAN bus based on CANable/CANtact open hardware, flashed with dual firmware CANtact and Candlelight (switch selectable) and equipped with termination resistor switch Downstream USB […]
