The Desk of Ladyada - Ring a Ding Ding it's time for a PiCowbell Duet
45This week we've got two PiCowbells we're testing - one is our MCP2515 CAN Bus 'bell we designed a few weeks ago. It uses the SSOP version of this chip to stay nice and slim for the narrow Pico footprint. we tested this board successfully using our Feather M4 CAN as the 'other side' - speaking of, we've also been refactoring our CAN/MCP2515 arduino libraries (https://github.com/adafruit/Adafruit_MCP2515) to be a little easier to use. the other bell is DVI output, using a mini HDMI connector. we designed this a few Desks ago, now it's time to try it out! we just had to make a new picoDVI pin definition and we have video out! we also got some UWB design prototypes ready for testing, these are kinda neat chips that are designed for indoor location/triangulation. finally we're working on a new design to allow QT Py (https://www.adafruit.com/?q=qt+py&sort=BestMatch) or Xiao boards to use our EYESPI cables for the small SPI displays in the shop (https://www.adafruit.com/?q=eyespi&sort=BestMatch)
The Great Search - Narrow-body FPC connector with 18 pins and 0.5mm pitch
https://www.digikey.com/short/fptn3hh3
We've searched for FPC cables connectors before on the Great Search (https://blog.adafruit.com/2020/08/02/desk-of-ladyada-when-searching-for-fpc-connectors-its-good-to-be-flexible-adafruit-digikey-deskofladyada-thegreatsearch/) but this time we're going to try to find a specific size: we need a 18-pin 0.5mm pitch bottom-contact connector for use with our EYESPI cables and boards (https://www.adafruit.com/?q=eyespi&sort=BestMatch) but we don't want it to be too wide! Most are 13.4mm wide, which is 0.525" wide, and we want it to be no more than 0.5"! Lets look for a slimmer cable connector that will fit on the PCB at 0.45" or less - but still fit all our specifications.
