Hey Guys,

nearly finished the design for my MIDI USB DAW Controller. One thought I had was for future expansion Daisy Chaining teensys.

What would be best way for acheiving this? I was thinking about using UART to connect the 4.1 as the "Master" and the T4.0 as a future "Slave". I assume i'd have the slave do all the hard work and then pass the results back to the master which connects to the PC via usb?

Thats roughly what I was thinking. Id be using this library and using the pipes to merge the data.

Sorry and an added extra. if i have a slave which isn't being connected via USB am i able to connect its VIN to the 4.1's VIN and leech the 5v from that? I understand there would be a current limit from VIN (I assume 500ma total between the 2 boards?)

PC USB -> t4.1 (master) - master VIN -> t4.0 (slave) VIN
