We got tired of flaky debuggers and cheap USB-to-serial converters, so we decided to design a more elegant and rugged solution to make debugging easier. Featuring an on-board Xilinx FPGA programmer, isolated dual USB-to-serial adapters, and dual USB-to-I2C adapters, you can bring-up and debug custom hardware faster. We’ve defined a standard pinout for the Samtec[…]
We routinely use off-the-shelf USB cables for debugging and testing of our designs. Whether we’re qualifying an off-the-shelf USB charger for a customer application or testing a custom design’s USB port, it’s convenient to have bare leads attached to a USB connector. With USB C, it becomes challenging to solder directly to the connector, as the pins are[…]
Santa brought us some early Christmas presents this year with a Vision Engineering Mantis stereo microscope and a Wiha screwdriver set. The microscope will come in handy when testing and debugging high-density, fine-pitch surface mount PCBs, like the design in our last post. Happy Holidays everyone!
The team is finishing up a week of serious engineering with a thorough peer design review of principal engineer Jonny‘s 16-layer HDI PCB designed with Altium Designer and SolidWorks. At the center: a massive Xilinx, Inc. Zynq UltraScale+ MPSoC (FPGA fabric + 64-bit ARM SoC) part. Two banks of DDR4 2400 MT/s memory (from Micron[…]
We are nearly finished with this prototype and manufacturing test PCB, designed with Altium Designer! This first-run prototype will be used to test the mechanical fit of connectors and the bring-up of crucial electrical circuitry.
These photos are from an optics project. This lens which has the half moon cut out of it is a hot mirror. Hot mirrors reflect infrared light and allow the visible light spectrum through. We cut these with a diamond-coated end mill. We cut through this mirror at a speed of 1 inch per minute.[…]
