  • In order to get this to work properly in Linux, the include of NewSoftSerial.h is necessary. Otherwise the tx will be stuck on and you will have problems communicating with it.

  • Thanks for doing this guys. I'm new to the field and find the products you sell to be interesting and educational at the same time. I really appreciate getting $30 off my order.

No public wish lists :(
