To the average microcontroller, Ethernet networks are quite a step up from the basic I2C, SPI and UART interfaces, requiring either a built-in Ethernet MAC or SPI-based MAC, with tedious ...

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 ...

The P42 Pico2 M.2 may look like an M.2 module, but it's actually a Raspberry Pi RP2350 development board in M.2 2230 form ...

This flip-chip compatible library in Dongbu HiTek 130nm features a fail-safe GPIO, two standard GPIOs, a 5V GPI, and 5V I2C-compliant ODIO. The GFGPIO is a highly configurable 5V tolerant, ...
