BPK LCD Driver Board- Part Number 6-201,

Serial LCD 2x16, Part number 6-111

Serial LCD 2x20, Part number 6-121

Serial LCD 2x40, Part number 6-131

Serial LCD 4x20, Part number 6-141.

Suitability

The BPK Serial Driver Board is a daughterboard that attaches to LCD modules and converts

the standard 4 or 8-bit parallel interface to a more easily managed serial interface at either

2,400 or 9,600 baud. It is compatible with all Hitachi 44780 controllers (or equivalents by OKI,

Samsung etc) with up to 80 on-screen characters. It is not suitable for 4x40 displays.

Connecting the BPK Board

LCD Connection- Non Backlit LCDs

The BPK board is supplied with SIL and DIL connectors- select the most appropriate connector

for your LCD. Non-backlit LCDs will have either a 14x1 pin or 7x2 pin arrangement- the

supplied connectors are 16x1 and 8x2- trim these down to suit the LCD.

Solder the selected connector to the BACK (component, non-display side) of the LCD using

the shorter length pins. Place the two double-sided foam pads on the back of the LCD to

prevent the LCD and driver boards from touching. Position the driver board over the header-

ensure that pin 1 is connected to pin 1 and that BPK pins 15 and 16 remain un-connected.

Solder in place

LCD Connection- LCDs with Backlighting

The BPK board is supplied with SIL and DIL connectors- select the most appropriate connector

for your LCD. Backlit LCDs will have either a 16x1 pin or 8x2 pin arrangement- the BPK board

assumes the back-lighting will be connected to pins 15 (Anode) and 16 (Kathode) – check

this configuration is correct before proceeding further.

Solder the selected connector to the BACK (component, non-display side) of the LCD using

the shorter length pins. Place the two double-sided foam pads on the back of the LCD to

prevent the LCD and driver boards from touching. Position the driver board over the header-

ensure that pin 1 is connected to pin 1. Solder in place

Connecting up the Driver Board/LCD

The Driver Board requires just 3 connections, incoming signal, ground and +5v at

approximately 2mA (excluding back-lighting) making it suitable for driving from either of the

BASIC Stamps.

DB-9 Socket

Connect the signal line to pin 3 and ground to pin 5. Some PC software requires handshaking

so you may need to make the following connections:

1 to 4 to 6

7 to 8

DB-25 Socket

Connect the signal line to pin 2 and ground to pin 7. Additional connections that may be

needed are:

Pin 4 to 5

... Power for the back-lighting is supplied via the 3-pin header. The back-lighting is selected On or OFF by the B/L jumper. The back-lighting current is set by resistor RBL to approximately 200mA (0.8V/3R9) or 170mA (0.8V/4R7) for the 6-111 and 6-201 products. RBL may be adjusted to suit particular LCDs but always ensure the maximum back-lighting current is not exceeded ...
