If you're interested in something low-power and not running a general-purpose OS like Linux, watch for the launch of the Precursor [1]. The main processor (RISC-V on an FPGA) seems to be more powerful than an ESP32, and they rejected the ESP32 for the WiFi component specifically because of the low-power state transition issues. The intended application is a stand-alone secure enclave complete with LCD, keyboard, and audio, but it will be interesting to see what hacks are developed for this hardware.

- mwcampbell 6y agoTo be clear, it looks like they've had to compromise on power consumption versus performance in their FPGA-based prototype: https://betrusted.io/betrusted-architecture/ https://betrusted.io/betrusted-architecture/ They plan to move to a custom ASIC later: https://betrusted.io/dev-plan/ https://betrusted.io/dev-plan/
