Badger 2040 W (Pico W Aboard) review

Reading Time: 2 minutes

Talking of power, you will want a portable way of supplying it. To this end, there’s a JST battery connector on the rear. If you buy the accessory kit version, you get – along with a lanyard – a 2×AA battery pack with a Velcro patch to stick it to the rear of the board.

Alternatively, you could use a standard USB power bank connected to Pico W. Both solutions are a little chunky, though, so you might prefer a slimline LiPo battery pack.

Easy to program

When first powered up, the Badger 2040 W launches into ‘Badger OS’ with a scrollable menu of icons to choose demo programs and tools. These include a badge, digital clock, e-book reader, interactive checklist, news headlines, and weather dashboard.

Naturally, you can connect Pico W to a computer via USB to customise the examples or create new programs – in MicroPython or C/C++. Pimoroni’s standard PicoGraphics library makes it easy to add bitmap images, and several fonts are supported. You’ll need to add your Wi-Fi credentials to try out examples such as news and weather, as well as setting the correct time via NTP.
