The bottom LED (LED1) is the 'Status' LED and is typically red. The top LED (LED2) is the 'Connect' LED for the Bluetooth module, and is typically green. The 3V3 for the module is derived from the 3V3 output on the Xprotolab therefore, it will work whether powered by the DC barrel jack or the USB connector on the Xprotolab. ![]() To connect the Bluetooth module, I had to use air wires to connect to the expansion jack on the right of the Xprotolab, since these pins are not broken out anywhere else. ![]() To connect these, I used 0.024 inch traces on the top layer, with vias connecting the top and bottom ground planes surrounding them in an attempt to shield the traces. Xprotolab PlainXprotolab Plain is an Oscilloscope, Logic Analyzer, Waveform & Clock generator all. The BNC jacks are from Sparkfun therefore, the parts used in Eagle are from the Sparkfun library (linked in the GitHub repository below). To make this board, I first created the schematic and board layout, then sent this to OSH Park for production. Two rows of I/O pin headers are used to bring the Xprotolab I/O pins to the edge of the board. In addition, this board also adds a 5V switching regulator so that the Xprotolab can be supplied by a 6.3-30V power supply, as well as a Bluetooth module that allows the wireless use of the Gabotronics Xscope computer interface. Therefore, this breakout board converts the two analog inputs, arbitrary waveform generator, and trigger pins to BNC jacks. sensors, frequency counters, etc.) or with oscilloscope probes. However, it is sometimes necessary to use this oscilloscope with other instruments that use BNC connections (i.e. The XMEGA Xprotolab is a convenient mixed-signal oscilloscope (MSO) with an arbitrary waveform generator fitted to a DIP form factor.
