 Microcontroller – LPC2377  Utilizing I2S, oscillator, UART, SPI  144 pins – most complex component  Voice Recognition Module  HM2007 has own PCB with many components  Microphone failure/inaccuracy = Module failure  Amplifier – LM4950  Regulators – LM317 and LM7805  Inputs are 12V and 5V, outputs are 5V and 3.3V

 High – safety risk  Medium – no safety risk, but device largely dysfunctional  Low – no safety risk, minor feature not operational
