“Not as versatile as some displays (it’s tricky to show certain letters), but works well and is good value for money.”

“I believe my zeroseg is working perfectly. I thought your assembly instructions were very clear. Also, I found the README in the ZeroSeg folder very useful. I used a long lead 40 pin connector instead of the one with the kit so I could add additional devices, which also work. now.”

“Interestingly, I cannot buy the 3 main components cheaper than the complete kit, so excellent value. Assembly was simple, although I will omit the chip socket next time so that the card can be mounted with the displays and switches protruding through a plain cover. My existing application is written in C/C++, and I found it easy to operate using just GPIO lines 8,10,11, thereby avoiding SPI activation and python libraries. In fact I can use any three GPIO lines because my zeroseg will not be mounted directly onto the 40 pin connector.”
