  • We use a pair of tweezers to dig out the last bits behind the motherboard.

  • The missing piece: a small interconnect board for the power and volume buttons. We find the following chips:

  • IDT P9221 wireless power receiver

  • Lattice Semiconductor iCE40LM1K-CM36 iCE40 FPGA

  • Cirrus Logic CS35L35A audio amplifier

  • Texas Instruments LM3644 1.5 A camera flash LED driver

  • With the Mate's brains dissected, it's time to head towards the other end of the phone and check out its fancy footwork.

Usamos un par de pinzas para extraer los últimos bits detrás de la placa madre.

La parte que falta: una pequeña placa de interconexión para los botones de encendido y de volumen. Encontramos los siguientes chips:

IDT P9221 1827SC SL-15 Receptor de potencia inalámbrico IDT

LMIK36 B8283V26 PHIL
