Adafruit Feather nRF52840 Sense [ID: 4516] (M4F, IMU, PDM mic, BMP280, LSM6DS)

Description: Adafruit Feather nRF52840 Sense (Product ID: 4516) https://www.adafruit.com/product/4516 Bought many of these for a project, but ended up replacing this board with a custom solution using different sensors. If you want to place a bulk order and want a discount, feel free to make me an offer or send me a message. Here's a copy of the description from Adafruit. Note that the board I'm selling uses the LSM6DS33 (an excellent and quite sensitive 6 DOF accelerometer and gyro), which was recently replaced with the LSM6DS3TR-C on this SKU. --- The Adafruit Feather Bluefruit Sense takes our popular Feather nRF52840 Express and adds a smorgasbord of sensors to make a great wireless sensor platform. This Feather microcontroller comes with Bluetooth Low Energy and native USB support featuring the nRF52840! This Feather is an 'all-in-one' Arduino-compatible + Bluetooth Low Energy with built in USB plus battery charging. With native USB it works great with CircuitPython, too. Like the Feather nRF52840, this chip comes with Arduino IDE support - you can program the nRF52840 chip directly to take full advantage of the Cortex-M4 processor, and then calling into the Nordic SoftDevice radio stack when you need to communicate over BLE. Since the underlying API and peripherals are the same for the '832 and '840, you can supercharge your older nRF52832 projects with the same exact code, with a single recompile! This Feather is also a BLE-friendly CircuitPython board! CircuitPython works best with disk drive access, and this is the only BLE-plus-USB-native chip that has the memory to handle running a little Python interpreter. The massive RAM and speedy Cortex M4F chip make this a good match. Make centrals or peripherals with the ease of CircuitPython. A chorus of supporting sensors surround the module so you can do all sorts of environmental and motion sensing: ST Micro series 9-DoF motion - LSM6DS3TR-C Accel/Gyro + LIS3MDL magnetometer APDS9960 Proximity, Light, Color, and Gesture Sensor PDM Microphone sound sensor SHT Humidity BMP280 temperature and barometric pressure/altitude Features: ARM Cortex M4F (with HW floating point acceleration) running at 64MHz 1MB flash and 256KB SRAM Native Open Source USB stack - pre-programmed with UF2 bootloader Bluetooth Low Energy compatible 2.4GHz radio (Details available in the nRF52840 product specification) FCC / IC / TELEC certified module Up to +8dBm output power 21 GPIO, 6 x 12-bit ADC pins, up to 12 PWM outputs (3 PWM modules with 4 outputs each) Hardware SPI, UART, I2C and I2S on any pins Pin #13 red LED for general purpose blinking, Blue LED for general purpose connection status, NeoPixel for colorful feedback Power/enable pin Measures 2.0" x 0.9" x 0.28" (51mm x 23mm x 7.2mm) without headers soldered in Light as a (large?) feather - 6 grams 4 mounting holes Reset button SWD debug pads on bottom of PCB Works out of the box with all of our Adafruit FeatherWings! (Even the UART-using ones like the GPS FeatherWing)
