Really Large Size 7 Segment Display with SPI Interface – 8 Channel SPI Relay Board
https://www.electronics-lab.com/project/really-large-size-7-segment-display-with-spi-interface-8-channel-spi-relay-board/
This is an SPI Interface multichannel relay board for high voltage AC or low voltage DC loads. It is ideal for controlling LEDs lights, coffee machines, fans, pumps, or other high-voltage electrical appliances. The board also breaks out the SPI header, so controlling other boards is still possible. Each relay can handle current up to […]
