Seon Rozenblum, better known as Unexpected Maker, has recently launched what they claimed to be the world’s smallest fully-featured ESP32-S3 module it packs all the peripherals, and wireless connectivity features of an ESP32-S3 module and features the tiny package size as the original TinyPICO Nano. The board will come in two varieties one with an Onboard antenna and the other with an u.FL connector onboard making sure that it will fit your needs.

The board centers on ESP32-S3FN8, boasting 2x Xtensa LX7 cores clocked at 240MHz, alongside 1x RISC-V, 1x FSM, 512K SRAM, 8MB PSRAM, 8MB Flash, and 27 GPIO pins.

Previously we have covered many different types of development boards and display modules powered by the ESP32-S3, including Waveshare ESP32-S3 GEEK, LILYGO T4 S3, Adafruit Metro ESP32-S3, feel free to check them out if you are interested in those.
