I have a Cobra II Wifi and an Extender (https://www.ghielectronics.com/catalog/product/439). I am unclear as to how to connect them. The Extender came without any gadgeteer cables or instructions. The product page similarly contains no information. It also seems like there is a battery slot.
- How do I actually connect the extender to the board?
- Does the extender need a battery. If so, what type?
