Hardware accelerated point cloud streaming with LattePanda Alpha and Realsense D400

This is more a technology than cool project. It takes advantage of the fact that Kaby Lake (in my case LPA with m3-7Y30) is the first Intel architecture that supports hardware accelerated HEVC Main10 (10 bit encoding). LattePanda Alpha grabs data from Realsense D435 depth camera, hardware encodes it...

Re: Questions for Battery Management.

I am much in favor of using the DC_IN power feed method. Simple and "even a caveman can do it". Caveman here ;-) You can use DC_IN also for battery but you will need step up DC-DC 12V power converter. Note that there is no BMS in this solution - you have to charge the batteries externally and make ...

The USB 2.0: [ 1057.752370] usb 1-3: new high-speed USB device number 10 ...

Powering from LiPo battery

Hi, In LattePanda Alpha/Delta user manual there is information about LiPo battery port: [...] and Alpha has an extra 7.8v Li-polymer battery port. You can power it by PD adapter, 12v DC input or recommended battery (alpha only) I have two questions: 1. Where is the LiPo battery port in Alpha? 2. Is ...
