the Raspberry Pi 4 has six SPI controllers, six I2C controllers, and six UARTs – all on its 40-pin header. You can’t make use of all of these at once, but with up to four different connections ...

This is a simple example of what you can do with a logic analyzer and a Raspberry Pi with a 40-pin header. Let’s ramp it up! On the Pi board alone, I2C is used in a few different places ...

The LCD display requires only two pins (I2C) on the Raspberry Pi GPIO to function, leaving the other pins available for your project. Features of the Pi display include : The LCD and Keypad Kit is ...

The Raspberry Pi board has a 40-pin GPIO header on it that needs through-hole soldering, along with bits like the Ethernet and USB ports. These require robust solder joints, which can't be done ...

The Raspberry Pi 4’s GPIO header also supports more connections, with UART, SPI, and I2C interfaces each supported on four additional pins, and with fixed support for clock stretching over I2C ...

For years, Raspberry Pi has been known for ... be connected via standard protocols like UART or I2C). It can also be used to convert some GPIO pins to existing protocols (such as extra SPI pins ...

The Raspberry Pi Pico is fitted with the Raspberry Pi ... MISO, and SCK), and one I2C/TWI (pins A4 and A5 as SDA and SCL). The Pico, however, doubles these numbers. It offers two UARTs: the ...

Multiple Kickstarter project creator Doug Gilliland has now launched his 17th project via the crowdfunding website, offering a Raspberry Pi I2C Multiplexer for the small single board PC.

The Raspberry Pi Pico is a very handy microcontroller with plenty of GPIO pins to tinker with. Each of these pins is designated to a particular protocol but none of that matters to maker and ...
