What I am working on, and where each piece of it lives.

An augmentative and alternative communication device for autistic people who do not speak, or whose speech is not always understood by the people around them. It records short phrases and plays each one back from its own button, offline, with no internet involved. The point is the price: imported commercial devices cost more than most families in Piauí can pay, and the ones who need them most are the ones priced out.
The working prototype records into three slots on an ESP32-S3 with an ES8388 codec, on bare ESP-IDF. This site is the dissemination platform the project calls for: the technical documentation carries the pin map, the wiring diagrams and the build steps, so another institution can build the device instead of buying it.
