PCBs for an alternative console and simulated amplifier interface for the ESP32-S3 microcontroller interacting with Logitech® Z906 Surround Sound Speakers
Open-source TLS 1.3, WiFi, and Ethernet ISA card for vintage PCs (XT/AT/386/486). ATF1508AS CPLD + ESP32-S3
This dual-MCU repository features a heterogeneous architecture pairing an ESP32-P4 application processor with an ESP32-C5 Wi-Fi 6/BLE hub. Linked over a high-bandwidth 4-bit parallel SDIO interconnect, this design decouples heavy multimedia task execution from the networking stack to completely eliminate application interrupt starvation.
