Nordic Based Bluetooth Speaker Programming -- 2

Job ID: 33852094

Budget: €250 – €750 EUR

I have a board with just the NRF5340 as microcontroller and audio amplifiers through I2S.
It´s almost a standard bluetooth speaker and the job is the complete programming of it (buttons, energy management, audio receiving and playing, etc) based in the user manual. There is no SD cards or file management. There is a user manual already written.
