Is That a Raspberry Pi Zero? Nope. ATMegaZero is an Arduino Compatible Board

ATMegaZero is an Arduino Leonardo compatible board based on Microchip ATmega32U4 8-bit AVR microcontroller that mostly follows Raspberry Pi Zero form factor with the 40-pin GPIO header, MicroSD card slot, and one micro USB port in the same location.

The MIPI CSI camera connector makes place for an OLED display connector, and the HDMI port is obviously gone, but you also get an 8-pin  header to easily install an ESP8266 based ESP-01 module to add WiFi connectivity.

  • Storage – MicroSD card
  • Display – 32-pin OLED display port compatible with 30-pin SSD1306 and SSD1331 based displays
  • Wireless Connectivity – 8-pin header for optional ESP8266 ESP-01 WiFi module
  • Expansion – 40-pin Raspberry Pi-inspired GPIO header with UART/SPI/I2C
  • Debugging & Programming – Micro USB port, 6-pin programming header
  • Misc – 4x LEDs, button
  • Power Supply – 5V via micro USB port
  • Dimensions – 65 x 30mm
  • Weight – Around 43 grams

The board works out of the box with the Arduino IDE for Windows, macOS, and Linux. The developer – Eddie Espinal – provides updates on his Instagram account, so there are plenty of photos, but I could not find that many other details there, with most of the information coming from a news article.

The board is not available just yet, but we’re getting close as Eddie mentioned he was “finalizing the testing and getting quotes for the first production run from different PCB manufacturers” three days ago.
