Compact Adapter Board Brings 5ms-Latency 60GHz Live Video Streaming to the Raspberry Pi

Compact Adapter Board Brings 5ms-Latency 60GHz Live Video Streaming to the Raspberry Pi

from hackster.io

Pseudonymous maker "NotNoiceComments" has designed an adapter board, which takes a 60GHz wireless video transmitter module and converts it for use with a Raspberry Pi — allowing for ultra-low-latency streaming from the Raspberry Pi High Quality Camera Module.

"I'm using it to stream 1080P up to 60fps [frames per second] from the RPI HQ Camera," NotNoiceComments explains of the compact board, designed to mimic the rough footprint of a Raspberry Pi Zero or Zero. [The latency] is 5ms or less."

The key to that low latency transmission: A commercial 60GHz video transmission module, designed to accept an HDMI input and transmit it wirelessly to a paired receiver, which converts it back into HDMI again.

"The reason why I'm using 60GHz is because of the extremely low latency. Normal Wi-Fi devices have 150-500[ms] delay depending on the network adapter," the maker explains. "Second thing is the cost of these modules. I was able to acquire a set of TX and RX for $30 vs $200 a set. It's a very [niche] use case."

NotNoiceComments is considering making the adapter board available to buy alongside the required transmitter module and receiver dongle, but notes that supplies would be limited: "[I] can sell a limited number of them unless someone wants to pay for $300 for them," the maker notes. More information is available on the project's Reddit thread.
