Excellent board if the differences work for you - please note the new OPTION (which I have not seen mention of on the forum before); OPTION PICO ON/OFF. (See manual page 83.  This gives access to the now externalised pins on this module.

OPTION PICO ON/OFF
When set to OFF pins GP23, GP24 and GP29 are not set up for normal
Pico use and are immediately available to use. Default ON


There was a useful introduction/discussion about this board back in January here:

As it is also possible to remove the Heartbeat LED and issue OPTION HEARTBEAT OFF and solder in a small jumper wire to the LED solder pads; and then hop another wire onto the GP24 solder pads as well, a total of 30 I/O connections would appear to be feasible!
