Based on low cost esp32 development boards.
SAK32 is an interactive Forth REPL for the ESP32. Type commands at the prompt to control hardware, fetch web data, share sensor readings across multiple devices and automate tasks — all without recompiling.
Connect via Serial (115200 baud) or Telnet (port 23) and you get an immediate interactive prompt. Define words, save them to flash, and they survive reboots. Load complex word sets from remote files with file-exec.
SAK32 is designed to be generic — no hardcoded IPs or device-specific code in the sketch. All site-specific configuration lives in your .fth files.
