I'm not sure if this is intentional or not, but it might be something to look at for future revisions:
The Pitaya Go has it's TX and RX pins (marked by silkscreen as pins P0.27 and P0.26, respectively. The pins that line up from the Pitaya-Link (when 3V3/GND/RST/SWDCLK/SWDIO are alligned) are marked "RX" and "TX", the reverse of the Pitaya Go. However, in order to use the CDC device created by the Pitaya-Link, the Pitaya Go must use pin P0.26 (marked "RX") to transmit on.
This took me a good bit to figure out, and if it weren't for the arrows in the diagrams, I might not have! 🙂
