Firmata is a firmware and host-side protocol for controlling microcontrollers from a computer, but none of the candidate sources describe Firmata itself; the list below contains only tools whose sources show they do not implement Firmata, so no product here answers the request directly. Within this set, ESPHome 9 and MicroPython 5 are the closest matches for microcontroller control from a host, though neither is Firmata.
A question back: Do you mean the Firmata firmware protocol for Arduino-style boards controlled from a host, and which board or host language are you using?
