![]() The original Arduino, the Raspberry PI, the Adafruit Feather and maybe the Raspberry Pi Pico, perhaps the BeagleBone, and one we’re seeing more and more, the BBC micro:bit. If we were asked to name some boards whose interfaces have become unintended de facto standards, those we’d end up with wouldn’t surprise most of you. Instead they’re left to the designer of the board who may not expect the device to become a widely adopted standard and thus may not think ahead as to how their creation might be used. Some are well designed and others not so much, but none of them are designed in the same way as the USB socket to be independent of specific hardware and with convenience for the desired application in mind. Almost all of them have an expansion connector, which serves the purpose of bringing out as many of the available interfaces in one place as possible. ![]() Oddly, many car accessory sockets are now unsuitable for their original purpose, being no longer designed to withstand the heat of a cigarette lighter element.Īnd so we come to the connectors on single board computers. Because there was no other handy way to access a 12 V power supply in a car it became the power source for the few electronic in-car accessories that were available, and has since evolved into the standard automotive power socket. The car accessory socket is by any standard a pretty awful power connector system, originating decades ago as the receptacle for an electric cigarette lighter. Sometimes though, an interface standard comes around by chance. How on earth did this become a power standard? Consider for example the USB-C port, instead of merely happening because a manufacturer decided to put a reversible high-speed data port with power capabilities on a machine, it was the result of many years experience and work on the part of an industry consortium. In most cases, an interface standard is the result of an effort specifically to create it. ![]() Do these standards make any sense? Let’s talk about that. There’s another aspect to these boards which has evolved certain among them have become de facto interface connector standards for hardware peripherals. USB TO MOLEX CONNECTOR SOFTWAREThey can be had from well-established brands such as Arduino, Adafruit, or Raspberry Pi, or from a Wild West of cheaper Far Eastern modules carrying a plethora of different architectures.Įveryone has their own favourite among them, and along with that comes an ecosystem of operating systems and software development environments. We are spoiled for choice when it comes to single board computers, whether they be based around a microcontroller or a more capable SoC capable of running an operating system such as GNU/Linux. ![]()
