The '''PineBuds Pro''' are open firmware capable ANC wireless earbuds. Some of the notable features include their light weight, 3 Microphones, ANC (Active Noise Cancellation), ENC (Environment Noise Cancellation) and high fidelity 6mm speaker. It is a fully community-driven side-project which anyone can contribute to, allowing you to keep control of your device even though hardware is proprietary.

== Buttons/touch sensors ==
=== Buds ===
One touch sensor is located on the outward facing surface of each bud near the Pine64 logo. In the default firmware these sensors are used to detect three types of user interaction:
# '''press/tap''' (touch and release in less than 1 second)
# '''long press''' (touch and hold, release after approximately 1 second)
# '''very long press''' (touch and hold, release after approximately 2 seconds)

=== Charging case ===
Charging case have a reset button in center under the lid, which when pressed happen a direct signal to both buds through the pins.

== Wireless charging ==
{{Under construction}}


PineBuds Pro doesn't have wireless charging by default, but you can add it. However, you need to know how to disassemble the charging case and solder bunch of SMT components to the PCB.

Pine originally planned to have wireless charging for the PineBuds Pro, but apparently for cost reasons they decided to cancel it. However, they left footprints on the PCB for wireless charging component. They also desiged COPO CP2021 component to be used. You also need a bunch of other components, such as resistors and of course [https://en.wikipedia.org/wiki/Electromagnetic_coil electromagnetic coil]. The places intended for the components, the footprints, are made for [https://en.wikipedia.org/wiki/Surface-mount_technology SMT (also called SMD)] components. That means you need [https://en.wikipedia.org/wiki/Soldering_station#Hot_air_soldering_stations a hot air soldering station] and experience.

'''Required tools:'''
* Picks/thin cards
* Screwdriver
* Hot air soldering station
* Tweezers
* Solder
* Flux
* Tape/glue

'''Required components:'''
* COPO CP2021
* WIP

'''So, let's do it:'''
# First open the lid and then try to press the case from the front edge with a plectrum or a thin card. There are two clips on each side. Soon the case will snap open.
# Carefully unscrew and remove the PCB from the case.
# Solder the necessary components to their respective footprints, use the PineBuds Pro Charging Case Schematic/COPO CP2021 2.5W Qi Wire Power Receiver Datasheet (below).
# Screw the PCB back into the place.
# There is plenty of space, tape/glue the coil to the bottom of the case.
# Close the charging case.
