is there a 300zi EVB Schematic?

include sensors connection, because i have a 407 dev but dont have much money to buy one ZI board.
but interested in the DR

@cheng
please refer to our user manual. If your are student and could contribute valuable soure code(application/algo) to our repo in github aceinna, maybe you could get free OpenIMU sample from sales guy.

@Li-YiFan i will try it, the openimu is not an open hardware?

OpenIMU hardware is not open, evb is open. you could check the schematic in our document.
