LED0..6 are also used for bootstrap settings. To avoid applying a
wrong voltage on the I/O pin coming from the LED, these GPIOs
should be sourcing current only, not sinking current.

GPIO0..28 are available, except GPIO25, which does not exist!
GPIOs can be set as input or output (GPIO13..17 are outputs
only), but they cannot be put into 3-state (high impedance or
disconnected)
GND
GPIO24
All GPIO pins are +2.5V tolerant only, voltage >
+2.8V may damage the module!
