Yeah, thats the guide that i used. Everything is soldered and done exactly how he said.... the only thing i wonder about is that yellow wire in step 3... i double checked my solder joints today, and miso and MOSI connect all the way in to the pcb from the module. When the tx and rx first make connection, i get a red LED flash on the sparkfun board, and then another quick flash when the throttle safety logic finishes. After that, just the green LED is on. Is there some way to verify that I am actually getting telemetry, and am going after the right problem?
