“Lovely little Arduino Uno compatable board with the larger B version of the RP2350 and a full compliment of everything you could possibly want including thoughtful little touches like a switch for reversing RX and TX on the UART pins! I was puzzled at first what they had done with all the copious GPIO on the 'B' chip as the Uno form factor is not particularly generous on IO pins. Turns out a lot of it comes out on the HSTX ribbon connector. Not sure I like that, depends on the availability of peripherals for that including a simple pin breakout. I notice Pimoroni does not stock anything else that responds to a 'HSTX' search except for a Feather format RP2350 board similar to this one.”
