I am building my own Enviro from breakouts, a mini garden and some redundant rain and wind sensors. The code is an adaptation of nopheads EnviroPlusWeb.
I now want to connect the particle sensor PMS5003 using the Part.Mat.Breakout but the recommended GPIO connections, BCM22 and BCM27 are not available on my mini garden. This has prompted lots of questions!

PMS5003 requires
5V > 5V
GND > GND
TX > TXD
RX > RXD
RESET > BCM27
EN > BCM22
And EnviroPlusWeb requires BCM4 for the fan speed control.
The breakout garden does offer some GPIO connections, 5, 6, 13, 19 and 26 but it is not clear to me if these are Pin numbers or BCM numbers. Does anyone know?
Also, can I rename BCM22 & 27 in my code to two of the available ones (5 6 13 19 26)?
And finally, BCM4 seems to be a dedicated clock output so possible can’t be redirected, might I have to peel this wire out of the ribbon cable to get it?
