MicroPython library for accessin the Quectel GNSS L76-L receiver over I2C. L76-L is a concurrent receiver module integrating GPS, GLONASS, Galileo and QZSS systems.
Using default I2C pins for ESP32.

utime.sleep_ms(1000)Custom I2C pins when using non ESP32 board.

i2c = I2C(scl=Pin(26), sda=Pin(25))
receiver = GNSSL76L(i2c)
while True:
for sentence in receiver.sentences():
print(sentence)
print("\n")
utime.sleep_ms(1000)More realistic usage with timer. If you get OSError: 26 or i2c driver install error after soft reboot do a hard reboot.
