+# Caveats
+
+The default build for the board only exposes the Arduino compatibility pins plus the "Zio" ones up to D25 (i.e. the rest are not in `pyb.Pin.cpu` nor `machine.Pin.cpu`).  Tuple-based access is documented but doesn't seem to exist.  So you'll need to edit `pins.csv`, [add the rest](https://gist.github.com/zwbrbr/f9202e3cc9288b459b8b116b83125c06) and rebuild to get access to them.

 Probably requires newer OpenOCD than 0.9.0, which complained "Cannot identify target as a STM32 family" despite getting a device ID.
