Notes
- Measurements: 85.6mm x 48.7mm x 10mm (L x W x H, including connectors). The mounting holes are M2.5 and 3.0mm in from each edge. The corner radius is 3mm.
- Badger W is fairly accommodating about input voltage (2.7V - 5.5V), so it's possible to use a variety of different batteries and battery packs. A 2x AAA battery pack fits behind Badger W nicely (double/triple AA and AAA battery packs will also work though). If you're using rechargeable (NiMH) batteries , we'd recommend using a 3x AAA battery pack.
- Alternatively, you can plug a LiPo/LiIon battery into the battery connector, with the following caveats. Please only consider this if the person wearing the badge is an adult and knows what they're doing with LiPos!
- A solid enclosure or backplate to protect the battery from damage whilst being worn is a very good idea (or you could use one of our Galleon hard case LiPo batteries).
- There's no battery protection included on Badger W, so you should only use it with LiPo batteries that include internal protection (all ours do).
- Badger W doesn't have battery charging circuitry onboard (this is so it's safe to use with either alkaline or LiPo batteries). You'll need an external LiPo charger to charge the battery (like a LiPo Amigo).
- * Badger W's onboard RTC (Real Time Clock) means it can go into a super deep sleep mode that only draws about 20uA of power, turning off the power that drives the Pico W and the display completely. It can be woken back up by the RTC or the front buttons. You can also read the RTC to keep track of the time and date, of course!
