GLO-416Y 4x16 Multifont Serial OLEDs

GLO-416Y displays receive serial data at 9600bps and display it on a bright, high-contrast OLED screen in a range of six font sizes. With this display we've implemented just about every serial-display user's wishlist: high brightness/contrast, wide operating temp range, low power consumption, multiple font sizes, compact footprint and low cost. Looking for a smaller display with similar features? See GLO-216Y/G.

GLO-416 Features

NEW v2: GLO-416Y has undergone a significant upgrade to a faster, more-capable interface. See the upgrade guide for details.

  • Brilliant OLED (organic LED) display
  • Fits standard 98x60mm LCD footprint (i.e., std 4x20 size)
  • Six font sizes from regular 4x16 to huge 1x4 characters
  • Accepts normal inverted serial or UART-direct noninverted
  • EEPROM storage of startup screen, 16 custom characters
  • Uses a superset of our terminal-style instruction set (BPP, ILM, etc.)
  • Deep inventory for no-lead-time delivery

OLED Instructions

GLO-416 works like a mini-terminal, displaying text and responding to traditional control characters like linefeeds, carriage returns, tabs, etc. via a superset of the instructions used by our other advanced displays (BPP, ILM, VFD, SGX). GLO also offers six font sizes, and EEPROM memory for a startup screen and custom characters.

Control codes not listed below are ignored.

Instruction (ctrl code) ASCII Hex
