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 […]

Pockit modular Linux computer takes hot plugging magnetic blocks

There have been attempts to create modular computers and smartphones to reduce electronics waste and improve user-serviceability over the years with initiatives and products like Google Project Ara, PinePhone and Fairphone3 smartphones, DevTerm mini computer, Olimex TERES-I laptop, and many more. Here’s another modular computer project that looks really cool. Pickit modular computer is comprised of an STM32+ESP32 based mainboard with a socket for an optional Raspberry Pi Compute Module 3. The board includes magnets and electrical contacts to snap and hot-plug modules/blocks while the computer is running. The video demo embedded further below, is really impressive, but let’s check out Pockit preliminary specifications first: MCU – STMicro STM32 microcontroller Wireless MCU – ESP32 dual-core processor with WiFi and Bluetooth LE CPU module – Socket for Raspberry Pi Compute Module 3 Expansion 24+ feature BLOCKS ready to use with instant connection using magnetic-snaps including Ethernet, Display (HDMI), audio, sensor modules […]
