Yeah, the ESP32 isn't exactly tiny. But, it's something I had lying around, so naturally I ported Snek to it. Somehow, I tend to collect tiny microcontroller boards. They're like coat hangers around here.

MicroPython uses a couple hundred kB of ROM; which is amazingly small considering how much Python that includes. Snek is a much less capable language, but it can squeeze down to about 32kB of ROM if you leave out the math functions.

Snek currently has ports for:

Adafruit Crickit FeatherWing (Atmel SAMD21)
Arduino Duemilanove (Atmel ATmega 328P)
ESP32
Adafruit Feather M0 Express (Atmel SAMD32)
SiFive HiFive1 Revb (RISC-V)
Adafruit ItsyBitsy (Atmel ATmega 32u4)
Arduino Mega (Atmel ATmega 2560)
Adafruit Metro M0 (Atmel SAMD21)
Arduino Nano 33 IoT (Atmel SAMD21)
Adafruit Circuit Playground Express (Atmel SAMD21)
POSIX (for testing and debugging)
QEMU for ARM (Cortex M3)
QEMU for RISC-V (rv32imac)
Arduino µduino from Crowd Supply (Atmel ATmega 32u4)

These range from 32kB of ROM and 2kB of RAM all the way up to several hundred kB of ROM and a bunch of RAM.
