+== Which hardware am I running on?
+
+There is no direct method for software written in MircoPython to discover whether it is running on a Raspberry Pi Pico or a Pico W by looking at the hardware. However, you can tell indirectly by looking to see if network functionality is included in your particular MicroPython firmware:
+
+[source,python]
+----
+import network
+if hasattr(network, "WLAN"):
+   # the board has WLAN capabilities
+----
+
+Alternatively, you can inspect the MicroPython firmware version to check whether it was compiled for Raspberry Pi Pico or for Pico W using the `sys` module.
+
+[source]
+----
+>>> import sys
+>> sys.implementation
+(name='micropython', version=(1, 19, 1), _machine='Raspberry Pi Pico W with RP2040', _mpy=4102)
+----
+
+So `if 'Pico W' in sys.implementation._machine` can be used to detect whether your firmware was compiled for Pico W.

 == Raspberry Pi Pico W
 
 Raspberry Pi Pico W adds on-board single-band 2.4GHz wireless interfaces (802.11n) using the Infineon CYW4343 while retaining the Pico form factor. The on-board 2.4GHz wireless interface has the following features:
 
-* Wireless (802.11n), Single-band (2.4 GHz)
+* Wireless (802.11n), single-band (2.4 GHz)

 The antenna is an onboard antenna licensed from ABRACON (formerly ProAnt). The wireless interface is connected via
 SPI to the xref:rp2040.adoc#welcome-to-rp2040[RP2040] microcontroller.
