Arduino® Nicla Sense ME The BHI 260 is capable of capturing data for the training of the BSX that can be trained on a PC. The generated smart algorithum then operates on this chip. 3.5 Bosch BME688 Environmental Sensor The Arduino Nicla Sense ME is able to perform environmental monitoring via the Bosch BME688 sensor (U6). This provides capabilities for pressure, humidity, temperature as well as nolatile organic compound (VOC) detection.
Arduino® Nicla Sense ME Nicla Sense ME Back View The Arduino Nicla Sense ME can be powered via micro USB (J7), ESLOV (J5) or VIN. This is converted into the relevent voltages via the BQ2512BAYFPR IC (U9). A schottky diode provides reverse polarity protection to the USB and ESLOV voltages. When voltage is supplied via the microUSB, a linear 3.3V regulator also provides power to the SAMD11 microcontroller used for programming the board as well as for JTAG and SWD.
Arduino® Nicla Sense ME 4 Board Operation 4.1 Getting started - IDE If you want to program your Arduino® Nicla Sense ME while offline you need to install the Arduino® Desktop IDE [1] To connect the Arduino® Nicla Sense ME to your computer, you’ll need a micro USB cable. This also provides power to the board, as indicated by the LED. The Arduino core is operated on the ANNA-B112 while the Bosch Smart Sensor framework operates on the BHI260. 4.
Arduino® Nicla Sense ME 4.8 Board Recovery All Arduino® boards have a built-in bootloader which allows flashing the board via USB. In case a sketch locks up the processor and the board is not reachable anymore via USB it is possible to enter bootloader mode by double-tapping the reset button right after power up. 5 Connector Pinouts Note: All the pins on J1 and J2 (excluding fins) are referenced to the VDDIO_EXT voltage which can be generated internally or supplied externally. 5.
