Hopefully the firmware development won't stall like it was with v4.
Rp2040 is a decent choice for relatively slow speed digital bus multi-tool, but the USB1.1 speeds will be somewhat limiting (IIRC I achieved somewhere around 700-800KB/s of serial data throughput). PIO is also flexible enough for some almost standard-but-nonstandard digital buses (for example, I used it to interface with 12-bit SPI-like interface- not many MCUs support word-widths that are not multiple of 8 for their hardware SPI interfaces).
- MegaDeKay 3y agoI think it was the case that they were just running out of memory to stuff new features in and gave up on it. If so, the RP2040 will give a lot more room for this. I have a V3 and it is a neat little tool. What isn't clear to me yet is what V5 will sell for. V3 was very cheap but this one has a display and some LEDs that will likely increase the price. Hopefully that increase isn't a big one. I gotta say though that the RP2040 is a game changer. It is popping up all over the place, from Bus Pirates to Switch mod chips. PIO, good docs, low price, and readily available is a solid combo of features.
