ATMegaZero ESP32 in the News

The ATMegaZero was modeled after the Raspberry PI Zero to take advantage of its sleek design and form factor but in the form of a microcontroller board. Similar to the Raspberry Pi Zero the ATMegaZero comes with 40 GPIO pins that can be used as input or output for interfacing devices and can be programmed using CircuitPython or the Arduino IDE software.

The ATMegaZero ESP32-S2 ships with the latest version of CircuitPython that supports the ESP32-S2. Just plug your ATMegaZero into your computer and it will appear in your filesystem as a USB flash drive!. Copy your code over, or edit your code directly on the drive. Is that simple!

As newer versions of CircuitPython are released, you are able to update as you require from


  • 32-bit 240 MHz single-core processor
  • 256Mbit (32MB) SPI Flash but we can only use 16MB at the moment due to firmware limitations.
  • 64Mbit (8MB) extra PSRAM
  • 2.4 GHz Wi-Fi - 802.11b/g/n
  • 3D Antenna
  • microSD cardholder
  • RGB Neopixel
  • FPC Connector for an OLED display
  • Raspberry Pi Zero form-factor
  • Dimensions: 65mm × 30mm × 5mm
  • Micro USB power
