GPIO Expansion For the eccentric makers among you, the ProtoLab comes with GPIO expansion pins pre-assembled – so you can add another board on top of this one for some really hardcore prototyping. If the rare white silkscreen doesn’t catch your attention, the features probably will. You sir, would be most incorrect with your wild assumptions! The stylish board in fact packs a lot of functionality in a subtle, tidy and low profile package. Without close inspection, you could be fooled into thinking it was just a perfboard-style breakout board with some terminal blocks around the side. Happy days! The ProtoLab is quite a deceiving little number. Lucky for me, the board comes pre-assembled, saving me a few burnt fingers. It had to be mine! Let’s take a look at the board and its features… I received my ProtoLab today – a Tuesday – a work day where I’m a lot less likely to have the motivation to get the soldering iron out. xScope is a powerful set of tools for Mac OS X that are ideal for measuring, aligning and inspecting on-screen graphics and layouts. It’s a bit of a fresh approach compared to some of the other offerings on the market, and its classy white ‘iPod-era’ colours caught my eye on eBay. This week another package came through the letterbox – a ProtoLab GPIO breakout board from AlienSpec. With any hobby I take an interest in, I always seem to end up buying masses of accessories, usually before I’ve even acquire the skills to use them! I’m a little further along on my Pi journey now, so I think these impulse purchases are becoming more relevant with time (wife…are you reading this?). Visualization of the signals and controlling the oscilloscope is done on the PC interface software (open source). It consists of a simple DIP module with a USB interface. It is the most inexpensive but feature rich oscilloscope in the market. On my board, I switched these two around, so when the COM port is connected, the red LED turns on.I love breakout boards. The Xprotolab Plain is a multi scope board created by Gabotronics. The bottom LED (LED1) is the 'Status' LED and is typically red. 5540 Pioneer Creek Drive Maple Plain, Minnesota 55359 (763) 479-3680 Fax: (763) 479-2679 ApDear Fellow Shareholder: The Board of Directors of Proto Labs, Inc. 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. 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. Nabízí zvýhodnné sluby z oblasti 3D tisku a konstrukních prací malým a stedním firmám v Moravskoslezském kraji i mimo nj. Aktuáln patí mezi nejvtí centra 3D tisku ve stední Evrop. Therefore, this breakout board converts the two analog inputs, arbitrary waveform generator, and trigger pins to BNC jacks. Centrum 3D tisku Protolab vzniklo v roce 2017 a zamuje se na profesionální prmyslový 3D tisk. The latter is much better - just a few cycles intrusiveness compared with an in-lined UART tx function. sensors, frequency counters, etc.) or with oscilloscope probes. XK-1 can only use xscope via UART (which is what you are specifying in your source code) whereas the XK-1A has the link pinned out to the XTAG2 connector. However, it is sometimes necessary to use this oscilloscope with other instruments that use BNC connections (i.e. xscopes-qt/xprotolabinterface. The XMEGA Xprotolab is a convenient mixed-signal oscilloscope (MSO) with an arbitrary waveform generator fitted to a DIP form factor.
