The first Display module prototype (apart from the ones I did on a solderless breadboard) is being built on 90 x 70 mm veroboard.
- 6 pcs 788BS LED Matrix
- 24 pcs Resistors 220 ohms
- 5 pcs SN74HC595
- 6 pin connector
Having underestimated the needed size of the veroboard, I ordered 90 x 70 mm veroboard. I cannot fit all the components on one 90 x 70 mm veroboard, so I am placing the 6 LED matrices and the 24 resistors for the columns. On another 90 x 70 mm veroboard will be the SN74HC595s and the 6 pin connector to the Core module.
The two veroboards will be placed on top of each other and connected with ribbon cable.
This is a Work in Progress and specifications may change!
Here is a few pictures of the board so far:

As you can see, I need to practice soldering a lot :-)
