ARE THE RESISTORS MARKED 2-3-4-5 THE SAME AS 16-17-18-19 ON THE OLD INSTRUCTION SHEET. I'm the guy who asked about using the RRRB board from Modern device,about 20 minutes after ordering a Uno I got it to spin the motors.Now I have a strange thing with both, sometimes a G0X20 will go one way two times in a row and then it will go backwoods with the same command without a minus.Using the Thermite serial port it seems to fill up after 3or4 commands and then I have to reset,its like the buffer does not clear. It does the same if I just use the Arduino serial port too.

Sorry about the slow response. The resistors are correct as you have marked them R2 - R5 on the v2 correspond to R16 - R19 on the v1. This has been corrected on the wiki.
