Product Description
The gCore, short for Gadget Core, 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. He wanted a development board that could be used for general purpose projects, but with advanced features often only found on commercial products. Just because it's a development board, doesn't mean you should skimp on features or functionalities.
Rather than wiring together several development modules, LCD displays, and power management circuitry, Dan has solved that problem with gCore's comprehensive set of features that you won't find anywhere else! Other development boards seem lack a lot of power related features that you would expect such battery power, sophisticated power management and monitoring, power up and down through firmware, and automatic low power shutoff.
Dan also wanted the best performance for graphics on the LCD and reading/writing to the local filesystem on a Micro-SD card. As a result, gCore became a sophisticated piece of hardware with a rich feature set and high performance. With gCore, users can focus on their application rather than worrying about the hardware. gCore is well suited for developers looking to greatly speed up development time for GUI based projects whether it's a personal project or for business.
Features
- LCD screen with capacitive multi-touch capability for great user interfaces and data displays.
- Dimmable blacklight controls to allow LCD operations in various environments.
- Compact size makes it easy to create handheld devices.
- Based on ESP32-Wrover module with 16MB Flash and 8MB PSRAM allow for complex firmware and features like Over The Air updates.
- Parallel interface to the LCD controller for better graphics performance.
- WiFi and Bluetooth.
- Micro-SD slot using 4-bit SD Mode communication for higher performance.
- GPIO headers and QWIIC I2C connectors for easy expansion .
- USB-C charging/programming port.
- Soft power controls (push button on/off).
- Internal voltage and current monitoring including charge status.
- Separate power management for powering and charging the system for optimal battery life.
- Code may be written using the ESP32 Arduino environment, Espressif's IDF or MicroPython. Both Adafruit-compatible and LVGL LCD drivers are available.
Support and Documentation
The gCore is an open source project and its GIT repository can be found at https://github.com/danjulio/gCore.
A great way to try out gCore without having to configure any environment or compiling code is to use gCore's Serial Programmer. There are many pre-compiled demos that are included to help you get started right away!
Please refer to the "Resources" tab to see all the other documents available.
What Can You do With gCore?
The possible applications are endless. Any application that needs to display information locally or wants a touchscreen display as the user interface can benefit from gCore's feature set. In addition, it's been designed for devices that can be portable or run on battery power making it great for projects that require the device to be mobile. Here are just a few of the projects that the gCore has been used for already.
Combine gCore with tCam-Mini and the tCam firmware for a full feature thermal imaging camera.
How about a lighting system remote control that turns on automatically when you pick it up?
Parsing and decoding a mjpg stream using gCore's dual CPUs and high performance display.
A video game emulator with 60 FPS graphics.
Explore your backyard using a remote controlled tank with video streaming.
Do all the math in hex or decimal with a programmer's calculator.
Stream from thousands of internet radio stations from around the world.
