that connects to the Breakout Board.
Table 2 Data In/Out Connector – Pin-Out

used to cause triggering or recording. Pins 4 and 5 are used to transmit
output signals.
2.17.2 Prototype Rework Area
The Breakout Board contains a prototype rework area for making custom circuits for rapid
development. The area consists of plated-through holes, 20 columns wide by 27 rows
long. The top row of holes connects to GND, and the bottom row connects to +5 V. The
remaining holes are not connected. Use the rework area to insert custom components
