Starting at $579, the LattePanda Sigma is really expensive. Not just for an SBC — at almost $600 (and more than that in some configurations), it’s a genuinely pricey bit of kit. But, with a 13th Gen Intel Core i5 CPU and up to 32 GB of LPDDR5 RAM, it’s much closer in specs to a fully-fledged desktop computer than its form-factor would initially suggest.
