Busdisplay is a small PCB that allows you to monitor the current data on an 8-bit bus. The data is shown on a 7-segment display. Both decimal mode (0-255) and hexadecimal mode (0x00-0xFF) are supported and could be set by a jumper.

This kit is useful for debugging your project, for example, showing current data on your retro computer bus. However, this is not a replacement for a logic analyzer and does not have that high bandwidth. You should verify that this board is suitable for your needs first!

This is a revision 3 of the project. It contains numerous improvements from previous versions, such as a functional ICSP header, a PIC microcontroller with built-in oscillator, and overall better solderability. The size is also optimized for 2x3 v-score panelization because it will firt 10x10cm panel perfectly, given that there are no edge rails.
