9600 Baud Serial Output Drivers for the Handy Board

 

The driver uses Port A, bit 7 pin (which is labeled as digital input 9 on the Handy Board), configures it as an output, and provides a serial signal of 9600 baud, no parity, 8 data bits, and 1 stop bit (9600 N-8-1).

There are two options for the driver: a TTL-level output, and an inverted TTL-level output. For use with the Scott Edwards Serial Servo Controller, get the inverted TTL level output.

Remember that the signal ground (-) of the Handy Board must be connected to the signal ground of the device with which it is communicating.
