ALC is a dream. One request that is stopping me from pulling the trigger:
The ZED-F9P can communicate over Serial and I2C at the same time. This is required for many RTK projects where contention for the I2C bus on the rover prevents you from issuing commands AND streaming correction data.
On my ZED-F9P projects, I run both serial and i2c on the rover in order to get 17mm accuracy and read current values/issue commands without having to manage a sempaphore on the i2C bus (which never really works great anyhow).
ALC will only let me do I2C -or- Serial, which makes it less useful for RTK correction projects on Arduino/ESP32.
Tx!
