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.

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!
