Product Description

The gCore is a high-end ESP32 development board designed to be a platform for portable graphics and GUI-based designs. It was designed by Dan Julio to scratch his own itch for a board to support his tCam and other projects with features such as ultra-fast graphics, high performance file storage, a charging system that doesn't put the load in parallel with the battery (confusing the charge controller), soft power control, a built-in RTC with alarm capabilities and the ability to monitor internal voltages and currents.

If you've ever struggled to kludge together traditional dev modules, LCD displays and power management circuitry for you application then you'll appreciate the sophisticated feature set. gCore frees you to focus on your application be it a control device, sensor display, or game and deliver a polished solution.

Code for gCore may be written using the ESP32 Arduino environment, the official Espressif IDF or even MicroPython.  A gCore specific Arduino library, and both Adafruit-compatible and LVGL (Light and Versatile Graphics Library) LCD and touchscreen drivers are available as well as a whole host of demo code to help you get started.

tCam Thermal Imaging Camera (gCore + tCam-Mini)

Combine gCore with tCam-Mini and the tCam firmware for a full feature thermal imaging camera.

 

gCore Controlling LIFX LED Light Bulbs via Wifi

Use gCore as the base for all kinds of remote controls. 

 

gCore streaming from an ESP-CAM

Parsing and decoding a mjpg stream using gCore's dual CPUs and high performance display.
