Makerfabs recently launched a compact board integrating the ESP32-S3 microcontroller along with a round LCD with capacitive touch. This product also includes a MicroSD slot for storage, a 3.7V battery connector and two Mabee connectors for I/O expansion.

As mentioned above, this new product from Makerfabs integrates the ESP32-S3 microcontroller compatible with the Arduino IDE.

According to the Wiki, this tiny board uses the SPI protocol to interface with the TFT display. The datasheet for this TFT module can be found here.

The two Mabee connectors shown below are compatible with Grove connectors. Each of these connectors seem to provide access to 1x 3.3V pin, 1x GND pin, and 2x I/O pins respectively.

Documentation related to this ESP32 board can be found on the Makerfabs Wiki. The company’s GitHub repository also includes a driver library and examples using the Arduino IDE. See the video below for a quick demo of the Makerfabs ESP32-S3 embedded platform.

Another company called Waveshare also recently launched a device with a similar form-factor integrating the RP2040 MCU along with a 6-axis IMU which can be suitable for portable applications that don’t require wireless connectivity.
