3V3 volt is not connected on PMOD side - wire can fix that. Once PINS A8 and B8 are set to 0 - PMOD side does the blinks on all pins Checked with 64x64 LED panel and it works * LEvel shifting for aoutput may not be needed - and for input could be done cheaper -…

MikroBusIO: common questions

How big is the MikroBusIO PCB?

The MikroBusIO measures 30 × 60 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the MikroBusIO?

55 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the MikroBusIO design files?

From the intergalaktik/Extension_Boards_for_Olimex_GateMate repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the MikroBusIO design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.
