New units won't boot

[Will Boekel]

Hello everyone,

I have just built up 2 units in tandem of the Rev C with the S2 lidar. I have been trying to upload the firmware and turn on the units for the first time but the only thing I get is the LRF on each unit to beep and a bright flash of the LRF then the LRF goes to a dim constant on state. On both units the screens do not power on.

I have tried combinations of screens and chips between the 2 units and some extras I had.

I am not too sure where to start looking.

Thanks for any help anyone can provide.

Most likely you have problems either with teensy or LCD is connected the wrong way. I advise to connect LCD with short jumper cables just to check if it works

I also had to order 3 LCDs from buydisplay to get the one fully working unit so you may have faced just faulty screen
