daisy-chain 4digit 7-segment SPI module
### DESCRIPTION
generic ebay/aliexpress modules do not have a 'feedthrough' .... so this is the pcb i designed to be able to loop through a number of SPI modules.
this is my first time designing and ordering a pcb so it will be quite a learning process.
### TECHNICAL DETAILS / COMPONENTS
uses 2 jellybeam 74HC595 in the SOIC version
because of space requirements current limiting resistors are omitted in rev1 and instead the limited current delivery of the 74hc595's i/o in combination with multiplexing is used.
>later revision intended to solve this with a 4 layer pcb/ expanded board.
v1 is designed for a 4 digit 0.56 inch display
### LEARN / TOPIC / BUILD INSTRUCTIONS
v1 to be assembled by hand by me ; but the 74hc595 chips could be reflow soldered on.
daisy-chain 4digit 7-segment SPI module
