The dsnB is a variant of the usbprog that can be used with the JAWS Deployment Support Network application to connect BTnode target nodes. It has three main connectors: A USB serial port connected to a software UART on the ATmega (pins
PE4), an ISP programming port connected to
UART0 on the ATmega and an ISP remote programming port connected to
UART1 and GPIO lines on the ATmega for programming of a target.
A demo setup with a BTnode as DSN node and a BTnode and sensor board as target node can be seen here:
