Your old ESP32 DevKit can run Zephyr too.
The DOIT ESP32 DevKit V1 is based on the ESP32-WROOM-32 with dual-core Xtensa LX6, 520 KB SRAM, Wi-Fi and Bluetooth.
But the fun part is using it with Zephyr RTOS.
You get access to GPIO, ADC, UART, SPI, I2C, I2S, PWM, timers, CAN/TWAI, watchdogs and more through Zephyr's hardware abstraction.
You can also experiment with MCUboot, OpenOCD debugging, Devicetree and Zephyr's RTOS architecture.
It is a great board for learning how embedded firmware moves beyond Arduino-style sketches.
ESP32 hardware + real RTOS concepts = a pretty good learning lab.

Made a new real-time fluid sim in WebGPU - "Particles4All".
Rigid bodies and fluid are all simulated by particles.
The combination of surface tension, anisotropic kernel and buoyancy makes the demo spectacular!
