What is SMARS Mini SMARS Mini is smaller version of the original SMARS Robot. It is 1/10 the size of the original, barely wide enough to house the two N20 Motors. Tiny Electronics SMARS Mini is so small it needs to have special, tiny electronics, to fit in the chassis. These include the VL53L0X Time of Flight sensor, that uses a tiny laser to sense objecst up to two meters away. These are just as cheap as the original sensor but much, much smaller.

Pimoroni Tiny2040 The brains of the SMARS Mini is a Pimoroni Tiny2040, which uses the same RP2040 chip as the Raspberry Pi Pico. Infact this chip has more flash storage than the Pico - coming in at 8Mb of flash storage.
