Jade also viable, although purchasing directly from Blockstream incurs supply chain risk. Able to flash onto generic hardware (M5Stack).

Jade's entropy accumulator adapts #Bitcoin Core's approach to an embedded device.

Both use a 32-byte state updated by folding the previous SHA-512 hash output back in, mixing in a counter and fresh entropy.

Core pulls from OS sources, hardware instructions, timing, and events. Jade uses its own hardware sensors like power and temperature, CPU counters, stack data, esp_fill_random, plus user input and camera noise at boot.

I would flee from anything that does not replicate this pattern of accumulative entropy.
