Joyy Technology's Muse Gadgets ESP32 is being hyped as a potential breakout hardware hit that could fuel the next wave of IoT and maker projects.
Comparing the positioning differences between the ESP32 and STM32: the ESP32 is Espressif's low-cost connectivity solution with integrated WiFi/Bluetooth — higher power draw, but deep sleep can reach 10µA; the STM32 is ST's industrial-grade low-power series, with the L series drawing under 1µA in Stop mode, but requiring an external wireless module. Selection should balance connectivity needs against power targets.
