Electronics Manufacturer Adafruit has launched the newest member of its QT-PY family of development boards, the QT PY-ESP32-S2 which comes with an incentive, a free Feather RP2040 for RP2040 Chip for orders starting at $99.00.

The 3rd board in a family which already features boards such as the Microchip SAMD21 based QT PY-SAMD21 Dev Board, and the Raspberry Pi RP2040 chip-based QT-PY RP2040, the QT-PY ESP32-S2 is a furtherance of the desire by Adafruit to create python-based development boards based on popular MCUs.

As the name implies, the QT-PY ESP32-S2 is based on the ESP32-S2 System-on-Chip (SoC) featuring a 32-bit Xtensa LX7 single-core processor with a clock speed of 240 MHz, 2 MB PSRAM, 4 MB Flash, and an ultra-low-power coprocessor based on RISC-V architecture. The SoC also features a 2.4 GHz WiFi, native USB OTG interface, ADC, 43 GPIOs, UART, I2C, LED PWM, LCD interface, SPI, I2S, camera interface, DAC, touch sensor, and a temperature sensor. The ESP32-S2 supports security features like eFuse flash encryption, integrated AES, SHA, and RSA algorithms, etc.

The board has the same form-factor and pin-out as the Seeed Xiao and can be soldered to a PCB through its castellated edges. It debuts STEMMA QT connectors for I2C bus and supports plug-and-play development with any MCU via a cable without B2B soldering. The board also features a 3.3V voltage regulator, USB-C, 13 GPIOs, UART, RGB NeoPixel with a power control pin, a reset button, a boot button, battery input pads, and 5x capacitive touch. Additionally, with a low regulator peak current output of 600mA and a deep sleep current of 100uA, the board is suitable for power-efficient application performance.

Key Highlights and Specifications of QT PY-ESP32-S2 Dev Board:

  • SoC: ESP32-S2; 32-bit Xtensa LX7 single-core processor @ 240 MHz, with 2.4 GHz WiFi, 2 MB PSRAM, 4 MB Flash, native USB, and an ultra-low-power coprocessor based on RISC-V architecture.

  • Power: 3.3V Power/enable pin, 3.3V regulator with 500mA peak current output
  • Serials: USB -C connector (for accessing built-in ROM USB bootloader and serial port debugging)
  • Connectors/Interfaces:
  • 21 x GPIO pins including;
    • 4x 12-bit ADCs (+1 more than Pico), 2x I2C, 2x SPI, 2x UART peripherals (one is labeled the ‘main’ interface in standard Feather locations), 16 x PWM outputs, 8 digital non-ADC/non-peripheral GPIO
  • Misc: Built-in 200mA+ Lipoly charger with charging status indicator LED, Pin #13 red LED for general purpose blinking, RGB NeoPixel for full-color indication, Onboard STEMMA QT connector, Both Reset button and Bootloader select button for quick restarts (no unplugging-replugging to relaunch code), Optional SWD debug port
  • Dimension: 50.8mm x 22.8mm x 7mm

The Adafruit QT PY-ESP32-S2 sold at $9.95, with the Pink Feather RP2040 given out as an incentive on the development board for orders starting from $99.00.
