在不断发展的电子元件领域，继电器——作为切换电路的关键设备，正在经历前所未有的技术变革。固态继电器（SSR）和机械继电器之间的争论由来已久。然而，从未来发展的角度来看，固态继电器正逐渐占据上风。本文将从耐用性、速度和能效三个方面，全面 ...

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 ...

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 ...
