Tiny, but mighty! This board with a powerful ESP32-S3 MCU measures in at 24.8mmx18mm (23.5mm for just the PCB, the USB-C connector sticks out a little bit). Despite it's small size it still exposes a wealth of GPIO connections - a whopping 34 in total. It does however have 'only' 4MB of Flash storage rather than the more typical 8MB found on most ESP32-S3 boards (and even 16MB on some).
- ESP32-S3FH4R2 dual-core Xtensa® 32-bit LX7 processor - up to 240MHz
- USB Type-C Port
- ME6217C33M5G low dropout LDO, 800mA (Max)
- WS2812 RGB LED
- BOOT button Press it and then press the RESET button to enter download mode
- RESET button
- 34 GPIO contacts (18 available on breadboard friendly castelated edges, 16 on the bottom of the board through exposed pads)
- 2.4G ceramic antenna
- Supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth® 5 (LE) although CircuitPython at the time of writing does not offer proper Bluetooth supports for ESP32-S3 chips, a NRF52840 based board will serve you better in that regard
- Built in 512KB of SRAM and 384KB ROM, onboard 4MB Flash memory and 2MB PSRAM
- Castellated module and onboard ceramic antenna, allows soldering direct to carrier boards
- Supports flexible clock, module power supply independent setting, and other controls to realize low power consumption in different scenarios
- Integrated with USB serial port full-speed controller, 34 × GPIO pins allows flexibly configuring pin functions
- 4 × SPI, 2 × I2C, 3 × UART, 2 × I2S, 2 × ADC, etc.
Due to the limited flash memory available on this board it hasn't been 'build' with esp-camera support - if that's something you want to use you'll have to roll your own build and sacrifice some other feature to make space (like the at the moment non-functional bluetooth)
