Desk of Ladyada - EYESPI 2.8" TFT revision & Scorpio revisit

Описание

With prices of TFTs back down to earth we're doing a lot of revisions and updates for our TFT breakouts. This week we looked at the 2.8" TFT with capacitive touch. We revised the board to go from having SOIC to TSSOP 74VHC245 level shifters, and with the space left over added an EYESPI connector. We're also trying to wrap the RP2040 Scorpio feather - this is an RP2040 board that is designed for driving 8 strands of NeoPixels with the NeoPXL8 library.

For the RP2040 SCORPIO, we have 8 level-shifted outputs that come out the end, and they may end up connecting to a looooong wire strand before hitting that first neopixel. To avoid ringing, we can add a small in-line resistor (say 100 ohm). But we are really tight on space! How can we fit 8 resistors into a 2mm wide strip of space? Behold the magic of 0804 resistor packs! We love packs for space saving and possibly even cost saving when manufacturing.
