In the interim I'm offering the MiniPCBv2 as a kit for $40, a $5 reduction.
The MiniPCBv2 is a bit more compact, but offers the same features in a less complex package. This makes assembly faster and less complicated. It is designed around the same Teensy 3.2/400 micro processor as the v1, but offers the WeMOS d1 mini wifi processor and additional auxiliary outputs. The Teensy is faster and mounting the OnStep firmware is a bit more straight forward than the STM32.
Let me know and I can get the MiniPCBv2 kit out to you right away. Shipping still $5 in U.S. $12 to 15 international.
