Happy New Year everyone, hope you enjoyed the holidays !!
Today we are going to talk about the latest trends of our hardware architecture.
New PCB disposition to drive the petals
We used to try to drive each LED with its own processor. However we could not manage to get every component to fit on the PCB petals. Moreover, the processors were underused as we barely needed half of their timer outputs. Therefore, further inside the Phyllo, we decided to add a layer with slightly bigger PCBs (let’s call them the petal controllers). They have a STM32F207VIT6 which can drive up to 10 LEDs.… Read more
