ClojureScript on Microcontrollers
summary
Shows running ClojureScript on an ESP32 using Espruino on ESP32 with a REPL over serial and Wi‑Fi, picking the WROVER module with WROVER 8MB RAM so cljs core (~30k js vars) fits; raises Espruino js var cap to ~55,000 and relocates flash partitions so cljs core loads (takes ~15s). Delivers custom PCBs with battery charging, LEDs and a solenoid lock demo, integrates UWB ranging, and publishes tools in the esprit repo on GitHub.
