The pinout of the two 7segement displays
for a modified version of the "LPC Debug Card" I would need the pinout of the 7segement displays.
The plan is to desolder the displays and then attach cables to the PBC and the other end of the cable will be attached to bigger 7segement displays or to an Arduino that has a Display which shows then the specific the message.
I hope that it is Ok to post it here.
Sounds like a cool project 🙂
See the below image, shown from the back of the board. The 7-segment displays are of common cathode type.
You don't necessarily need to remove the 7-segment displays to achieve what you want to do. You could solder wires to the 3.3V signal before the resistor network (ex L1_A for segment A of the least significant digit). This image is from the front of the board.
I have finished the first version for Arduino:
https://github.com/tankhunter8192/LPC_Debug_Card_Extension
In the folder "Arduino" is the specific data.
How is it working?
Hey!
I’m looking to take over this project with intent to make this a wireless system. Wanted to know if the schematics and cad files were open source? Also has the segment pinout have been changed for the new P80DB2 model? I’ve also noticed 6 pins to the left of the board, i’m assuming that is for programming?
Any help would be appreciated!

Hello,
Sorry this product is not open source. There are some differences in pinout compared to before, please see below. The 6-pin header pads are for JTAG programming of the CPLD.
