Who’s behind it

Made in York by Carefully Coded.

LittleSpec is designed and built in York by Carefully Coded, a small software and hardware studio.

LittleSpec is us building something a bit different and making a product that we've wanted to see for a while. After getting into SDRs we always wanted to explore on the go without a laptop (or without looking like a supervillain). So we built it ourselves, and hope it'll make getting into RF simpler on the go!
