    #M5Stamp Pico: an ESP32 miniature and powerful module

    M5Stack, MicroPython, Product Reviews | 1 min | 6151

    M5Stack is a technology company based in Shenzhen China, which specializes in the design, development, and production of IoT development toolkits and solutions, and today they have just launched a new device in its core series: the M5Stamp Pico; and awesomeness comes in small packages.

    I thought the M5Stack ATOM would be the smallest core possible, but I was wrong!. The M5Stamp Pico is even smaller and still very powerful. The M5Stamp is the smallest ESP32 based development board in the M5Stack family. It features an ultra-compact design with two fully-programmable low-power Xtensa® 32-bit LX6 microprocessors that run at 240MHz and the PCB is as tiny and delicate as a postage stamp (thus the name!).
