IZIRUN open-hardware STM32 development boards expose GPIOs through M.2 connector (Crowdfunding)

IZIRUNF7 STM32F7 MCU board with M.2 socket

M.2 sockets are typically used to connect wireless or storage expansion boards to laptops, computers, and SBC’s. But nothing precludes them from being used for another purpose, and earlier this year we wrote about Sparkfun MicroMod MCU boards with an M.2 connector for GPIOs, I2C, SPI, etc… IZITRON has expanded the concept with three slightly larger (IZIRUN) STM32 boards routing more IOs to the M.2 connector, and additional features such as built-in EEPROM and buttons. IZIGOBOARD carrier board is then used to host the STM32F0, STM32F4, or STM32F7 board in order to ease development. IZIRUN STM32 development boards IZIRUN boards specifications: Microcontroller IZIRUNF0 – STMicro STM32F030CCT6 Cortex-M0 MCU @ 48 MHz with 256KB flash, 32 KB SRAM IZIRUNF4 – STMicro STM32F407VET6 Cortex-M4 MCU @ 168 MHz with 512KB flash, 192KB SRAM IZIRUNF7 – STMicro STM32F769NIH6 Cortex-M7 MCU @ 216 MHz with 2MB KB flash, 532KB SRAM On-board RAM – IZIRUNF7 only – 8MB SDRAM Storage 16KB EEPROM  IZRUNF0/4 – 512KB […]

SX1303 mpcie lorawan concentrator card

I first noticed Semtech SX1303 LoRa baseband processor for gateways was in RAKwireless WisGate Developer Base equipped with RAK5146 SX1303 mPCIe LoRaWAN concentrator card. But n-Fuse now offers another option with their LRWCC3-MPCIE mini PCIe card that is an update to their earlier SX1302 based n-Fuse LRWCC2-MPCIE card announced last year. n-Fuse LRWCC3-MPCIE specifications are very similar with the differences highlighted in bold: MCU – STMicro STM32 LoRa Connectivity Semtech SX1303 digital baseband processor with 2xSX1250 and 1xSX1261 Tx/Rx front-ends Frequency Range – 863 to 870 MHz or 915 to 928 MHz Sensitivity 868 Mhz <= -125dBm at SF7, BW 125KHz <= -140dBm at SF12, BW 125kHz 915 Mhz <= -125dBm at SF7, BW 125KHz <= -140dBm at SF12, BW 125kHz Max RF Output Power – Up to +27dBm Listen Before Talk prevents collisions while accessing the spectrum.

OpenMV PureThermal STM32H7 board overlays thermal map on RGB image

OpenMV PureThermal Camera

We’ve been writing about OpenMV open-source camera boards programmable with MicroPython at least since 2015, with the latest model OpenMV Cam H7 based on STM32H7 Cortex-M7 microcontroller introduced in 2018. But the company has now gone a step further with OpenMV PureThermal board equipped with a more powerful STM32H7 dual-core Arm Cortex-M7/M4microcontroller, and supporting FLIR Lepton 2 to 3.5 thermal imagers, allowing the system to overlay the thermal map on top of the image like an augmented reality app would do. It can do so on the integrated LCD display or on an HDMI display. OpenMV PureThermal features & specifications: MCU – STMicro STM32H7 Arm Cortex-M7 @ 480 MHz) and Cortex-M4 @ 240 MHz microcontroller Memory – 64MB SDRAM Storage – 32 MB of QSPI flash for the firmware, a microSD card slot for saving pictures and machine vision assets Display 800×480 touch Screen LCD DVI out for driving an external display (compatible with HDMI TV up to 1080p30, or […]

Board::mini development tools offer a complete Vehicle-Hacking Platform (Crowdfunding)

board::mini base CAN bus automotive development board

If you are looking to connect to a vehicle’s CAN bus, then the newly launched open-source board::mini development tools include a board and expansion boards that will aid your application. BMC labs have introduced a development board based on the STM32 MCU and supporting expansion boards to increase the capabilities of the baseboard via a crowdfunding project.  As mentioned earlier, the board:mini base development board features an STM32 MCU at its heart and comes with a CAN transceiver. For those who do not know what a CAN transceiver is, it just transmits and detects data on the CAN bus. The board:mini project also includes three expansion boards designed to fit on top of the base development board.  The bmc::board project was born to produce development tools appropriate for both field- and industrial-prototyping work. These boards were not designed to sit on a workbench. We ourselves have a habit of strapping them to vehicles, but…the qualities that make them suitable for […]
