The entire system is powered by a single\u00a01.55V 75mAH silver-oxide button cell battery along with a boost converter to generate 2.8V supply required for the camera and other electronics. The main electronics board consists of the\u00a0STM32F411CE ARM Cortex M4 processor, memory for storing images, and the\u00a0nRF24L01+ RF transceiver chip. The ARM processor\u00a0implements the 8-bit parallel video interface to the camera\u00a0and\u00a0also provides a 6-24MHz reference clock required\u00a0by the image sensor. All\u00a0electronics will be enclosed in a sealed capsule made of\u00a0a bio-compatible material with the front face of the camera covered by a clear cap.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Capsule endoscopy lets doctors to see inside of your small intestine, an area that isn&#8217;t easily reachable with traditional endoscopy procedures.
