Waveshare has launched one other accent for the Raspberry Pi Compute Module 4 within the official IO Board service, this time splitting the one PCI Categorical slot out into 4 1x slots — accessible utilizing a intelligent packet change chip.
Waveshare unveiled its need to develop the Raspberry Pi Compute Module 4 IO Board service with low-profile add-ons late final yr, with the launch of a flat board designed to cut up the board’s single PCI Categorical slot into 4 high-speed USB 3.0 ports. Its newest design is one other four-way add-on, however this time performing an obvious magic trick: Multiplying the one port into 4.

Delivered to our consideration by CNX Software program, the add-on board sits on the IO Board’s single PCI Categorical slot and gives 4 1x slots of its personal — utilizing an ASMedia ASM1184 PCI Categorical packet change chip to develop the one lane obtainable on the Compute Module 4.
The board installs with no software program required, however customers might want to feed it with a 12V enter — and in addition to pay attention to energy limits for the PCIe playing cards related to its ports, which should draw lower than 1.5A from the every slot’s 3.3V pins.
The four-port enlargement board is now obtainable to order on Waveshare’s Chinese language outlet, priced at CNY144.90 (round $23.)
