There's nothing stopping a person from putting an ESP on a RPi B board format (or a Zero one), other than certain IO limitation. The upcoming P4 might be a candidate [0]. If you are interested in sbc in Pi form factors (B, Zero, CM3, CM4), then something I follow is CNX [1]. It will typically have notifications of any new Orange Pi, Libre Computer, etc.

- extraduder_ire 3y agoIt would be amusing if they used a pi2040 chip to drive the IO pins on such a board. I'm sure there's cheaper chips out there to do this.
- adolph 3y agoIt might make sense given pi2040’s PIO capabilities. Additionally, the RPi5’s io chip, RP1, might have some similar tricks inside. The Raspberry Pi Pico has a fascinating peripheral known as the “Programmable Input/Output” (PIO). This device allows us to write very simple assembly programs to emulate a number of different peripherals and communication protocols. https://www.digikey.com/en/maker/projects/raspberry-pi-pico-and-rp2040-cc-part-3-how-to-use-pio/123ff7700bc547c79a504858c1bd8110 https://www.digikey.com/en/maker/projects/raspberry-pi-pico-... RP1 is our I/O controller for Raspberry Pi 5, designed by the same team at Raspberry Pi that delivered the RP2040 microcontroller, and implemented, like RP2040, on TSMC’s mature 40LP process. https://www.raspberrypi.com/news/introducing-raspberry-pi-5/ https://www.raspberrypi.com/news/introducing-raspberry-pi-5/
