# CORE_D4 Lite

The CORE_D4 Lite board is second board in the CORE series of Microstorm. It is designed to be used in even smaller space where power and connectivity is required.

Compared to the CORE_S3, the CORE_D4 Lite is 30% smaller. This size can be achieved by stripping all the sensors from CORE_S3 and changing the processor from an ESP32-S3 to an The ESP32-PICO-D4. This seems like a downgrade, but this is not neccesarly the case. ESP32-PICO-D4 has different features than the ESP32-S3, Like on board MAC. When you have a board that features the CORE_D4 Lite and a PHY like the LAN8720, you can achieve 10/100 Mbps Ethernet connectivity. Which is usefull in industrial applications.

Aside from a different feature set and formfactor, the CORE_D4 Lite is fully pin compatible with CORE_S3. Just keep in mind that the formfactor is different.

# Features

  • 4 MB Flash
  • 512 KB PSRAM
  • WiFi & Bluetooth 4.2 (LE)
  • USB Type-C
  • Onboard dimmable White LED (GPIO 13)
  • Arduino, CircuitPython, Micropython, ESP-IDF

But wait... There's more! The CORE_D4 Lite is based around the ESP32-PICO-D4 microcontroller. This means all the features that the microcontroller provides, the CORE_D4 Lite has as well.
