$59.00 kit w/1 adapter (no LCD)

GLI2 - The new GL series 20Mhz controller board. Same compact size as the original GLI board but has an on-board -15v power supply to drive LCD panels up to 256x128 in size. Low cost adapters available for most of the popular graphic controller LCD displays, such as the SED1330, T6963C, KS0108, and the HD61202. Uses a PIC16F877 mcu, Max233 serial transceiver, 24LC256 I2C eeprom, a Max637 voltage booster and an LM7805 voltage regulator. The controllerís PORTA and PORTB pins are available for other uses and are brought to pin outs for easy connections. Requires 7-20v DC power supply.

GLI2 Controller is supplied with one LCD adapter (5 adapters to choose from)

GLI2 Adapters available (each has a trim pot for the LCD contrast) shown with their pin outs

More adapters will be added as the availability of different economical graphic LCDs becomes possible. If you already have a graphic LCD display and if its connections match any of the the adapters below then it can possibly be used with the GLI2 board, but may require some programming changes.

Demo firmware and docs*

*Existing firmware for the original GLiPIC board will be converted and be made available as soon as the code changes are made to accomodate the new GLI2 board

The GLI2 board uses different mcu pin assignments than the original GLiPIC board therefore all firmware written for the GLiPIC board will have to be re-compiled with the pin assignment changes. beyond that, no other changes on code should be required.
