|Project Building Glasgow|
|debugging PCB assembly so we can build a PCB to debug our PCBs|
If we make this work, then we can probably put a bunch of them together for <100eur each, but for now this is just an experiment.
Glasgow is described as an `open source multitool for digital electronics'; it's basically an FPGA with configurable level shifting for 16 ESD-protected I/O pins, so you can connect it to a whole bunch of random interfaces:
We ordered 50 revC1 PCBs and a stencil from JLCPCB.
- They asked for confirmation that the solder mask layer was meant to be missing the DNP parts, replied.
- They arrived and are in noopwafel's samla.
- We also have solder paste.
noopwafel plans to buy about 10 board's worth of components; the total BOM cost is about 70eur in these quantities.
- We managed to import a BOM into Mouser, and to break Digikey's BOM manager.
- YC248-JR-0710KL is fine (the 'L' is somehow an optional part of the part number...)
- The HX4K is 1eur cheaper..
- noopwafel has a BOM spreadsheet for managing this now; order split between mouser, digikey and TME.
We should put together some simpler boards in the reflow oven. noopwafel plans to try one of the iceGLITCH boards.
