Every figure here is checked against Espressif’s official datasheets. We’ve taken every care to keep it accurate — but datasheets are dense and mistakes happen, so if something looks off, please report it.

Which should you choose?

Both are built on the same ESP32-C61 SoC, so CPU and radios are identical — the choice is about memory, form factor and antenna.

These two are closely matched on the spec sheet — decide on price, availability and which footprint fits your board.
