pip3 install adafruit-circuitpython-bd3491fs

Usage Example

import board
import adafruit_bd3491fs
import busio

i2c = busio.I2C(board.SCL, board.SDA)
bd3491fs = adafruit_bd3491fs.BD3491FS(i2c)

bd3491fs.active_input = adafruit_bd3491fs.Input.A
bd3491fs.input_gain = adafruit_bd3491fs.Level.LEVEL_20DB
bd3491fs.channel_1_attenuation = 0
