Sure, after integrating USB 2.0 HS or 1Gb-Ethernet the pico2-board will cost more than $5. So, integrated high-speed interfacing with PC was not a nice-to-have option (for special chip flavor)?
- solidninja 2y agoI think the target here is low-power peripherals rather than speedy peripherals, and the price is very nice for that :)
- kvemkon 2y agoHere [1] someone asked to make RP1 I/O chip available, but actually RP2350 is what would fit the purpose.

- kvemkon 2y agoRP1 I/O chip on RPi5 has so many high-speed interfaces. I've been thinking RP2350 could be some smart I/O chip for a PC/notebook/network attached computers (with only 1 necessary high-speed connection).

- kvemkon 2y ago1.25 Gbps would be needed for low-pin-count SGMII interface to a PHY chip.
