Is there any Adafruit product that I can use instead of a nice!nano for a split wireless keyboard build.
Been googling this for a while now and can't find any definitive answer.
The nice!nano can be used without a TRRS cable for communication between the two halves. So there are absolutely no wires involved.
So far the information that I found indicates that this cannot be achieved with for example the Adafruit Feather 32u4 Bluefruit LE.
Can anyone confirm this?

Re: nice!nano alternative for split wireless keyboard
The 32u4 can't implement the same solution:
The board you mentioned uses an nRF52840, which can act as a BLE central. This code shows how to use it as a dual-mode device that acts as a central for a second peripheral, but registers as a peripheral (like a HID keyboard) to talk to a phone or a computer:

You need a board that can work as a BLE central device, and the '32u4 doesn't have enough RAM to run that code.Do you still need a TRRS jack?
No, there's a connection via BLE between the two boards. The central half reports back the keystrokes of both the central (usually left) and peripheral (usually right) sides.
