LCD Displays can be costly in terms of precious i/o lines in a micro-controller project. A backpack pcboard LCD controller with a single serial line input is the common solution.

So ... this is yet another serial backpack controller board!
So ... why would you want this K107?

• Top quality double sided PCBoard, with solder mask and silkscreen. More value for your money. Costs less and does more!
  1. Needs only a single +5 volt dc supply @ 10 ma plus up to 200 ma for LED backlight
  2. For displays with LED backlights, intensity can be controlled in software to PWM hardware on board
  3. Can accept TTL level True serial, or RS232 level Inverted serial selectable by jumper
  4. Power/Signal input connector compatible with standard servo/lcd cable
  5. Built in test mode, selected by jumper
  6. beep and 2 software switched outputs available
  7. Can physically accept 1x10, 1x14, 1x16, 2x7 display connector pin arrangements and 1x16 Flat Flex with K107RA adapter
• For DIYers, bare board available.
  1. can accept 16F84, 16F628, 16F648 PIC chips
  2. full access to 628/648 USART pins
  3. even unused pins have plated through via's for hand wiring
  4. holes and traces for resonator on pins 15-16
• Main design to accept the PH Anderson line of controller chips. The K107 board will work with his LCD 106, 107, 108, 117, and 118 chips.
  1. Wulfden currently offers with its K107 kits the LCD117 (9600 baud), LCD117 (19200 baud), or LD118 (2400 baud w/4 MHz resoantor).
  2. Anderson controller firmware can handle any Hitachi HD44780 compatible display in 2x16, 2x20, 2x24, 2x40, 4x16 or 4x20 geometries, under user control
  3. Supports a 'large number' display mode with a four line display (4x16 or 4x20). User defined characters, xy positioning plus the usual range of commands.
• For ** PICAXE users ** - the K107 (Rev 3) with the Anderson #108/#118 chip and resonator will run at 2400 baud and interface perfectly with your processor. For more details see my K107 Blog. You also may want to take a look at my PICAXE products page.
• For ** ARDUINO/Freeduino users ** - the K107 (Rev 3) with the Anderson #117 chip at 19200 baud will interface perfectly with Arduino and Freeduino. For more details see my Freeduino page. I have written and Arduino Library as well as a demo program for the K107

Basic K107 Product Line

1. Board Only - exactly what it says, just the K107 PCBoard
2. Board and Chip - K107 PCboard and Anderson chip
3. Board and Parts - the K107 PCBoard plus all the support parts EXCEPT the Anderson chip - assumes you already have one or are planning to do a custom program to your own blank chip.
4. Complete Kit - K107 PCboard, all parts and Anderson chip
5. Ribbon Adapter - the K107RA pcboard adapter board allows interfacing to displays that have 16 conductor 1mmm pitch Flat Flex (FFC/FPC) connections. Kit consists of board, 1x16 pinheader, and FFC/FPC connector
6. Special Display and adapter for the AMQRP PIC-EL project or Tom Lackamp's All In One Remote can be found here.

The kit of support parts includes 1x16 and 2x7 socket headers and a 2x7 pin header to cover the range of LCD connections. The 1x16 socket header may need to be cut down for 1x10 or 1x14 connections.
