The company emphasizes open-source development; per Wikipedia, public reporting in 2022 noted its move to the RISC-V instruction set architecture.
Discussion in the show
Weekly #001’s chapter “ESP32 成为’新乐高’，全民发明家时代来了” in the Chinese transcript (ESP32 as the “new LEGO”) discusses the boom in small hardware projects. Guizang remarks that ESP32 dev boards “have become the new LEGO — sold out every day, never enough stock”. This is a host’s observation about the maker community, not official sales data.
