The series of MicroMod modules by SparkFun presents a completely new approach to prototyping electronic devices. Instead of classic solutions based on goldpin connectors or bundles of connecting cables, laboriously connected by the user between individual boards, the constructors used ... an edge connector slot in the M.2 standard, used to connect hard drives in portable computers. Effect? A compact and fully professional platform that allows you to quickly create complete solutions in the field of modern embedded systems, based on any selected from a wide range of different processor models (ESP32, STM32, RP2040, SAMD51, etc.).
