open-source wireless graphical display - arduino code compatible

Discontinued


A general purpose wireless graphical LCD display unit. Powered by an Atmega328 with an Arduino bootloader.

The emonGLCD is designed to drive a 128x64 GLCD display based on the ST7565 driver. The board has a built in HopeRF RFM12B wireless module to receive data from the emonTx energy monitoring node or an emonBase (Nanode-RF web-connected basestation) which in turn could be pulled aggregated data from a web-sever to be displayed.

The emonGLCD has an on-board temperate sensor, light sensor and two tri-color ambient indicator LED's.

Features

  • ATmega328 with Arduino Uno bootloader
  • 128x64 ST7565 LCD display
  • White PWM LED backlight
  • On-board HopeRF RFM12B wireless transceiver module
  • Power supply: 5VDC via mini-USB conector
  • DS18B20 on-board temperature sensor
  • On-board LDR light-level sensor
  • Based on JeeLabs.org design. Uses Adafruit/JeeLabs GLCD library
  • Software RTC updated from the internet via emonbase.
