I found the TeenAstro-Project and I am quite impressed. A big thank you to all the people that have contributed.
I intend to build a TeenStar controller and would like to ask if anybody has to sell the PCBs? I'd like to build a Mini Main Unit V2.4.1 and a SmartHandController V0.1 2,4" OLED. If there is nobody who has something to sell, I would order at JLCPCB.
If I would do an order I could easily order more than I need. So If there is further interest in PCBs, tell me.
