Just wondering about the product, WR703N Expander, SKU: SS103990001. How does this product function? Does it have to be used in conjunction with the TP-Link WR703N, or can I use it on its own? Can I upload openwrt software of to it? Is there a data sheet that goes with it and potentially examples of projects that it is used with?
Thanks for getting in touch. That board is designed to be used with the TP-link WR703N router to provide DIY access and modifications to the usage. We haven’t had any time with it unfortunately as it’s a bit of a niche product, however, all of the documentation and info that Seeed Studio have made available for that product will be on their product page: https://www.seeedstudio.com/TP-Link-WR703N-Expander-p-1683.html
