Add mode No.L2C
have the same technical construction including electrical construction and mechanical
construction with L2A. The difference lies only the model number and some minor circuit and
component, as follows:
1. The two cameras have been reduced to one, and the corresponding lens versions have also been
changed.
2. The filter of 2.4G SDR is changed from qorvo885136 to RSFP2421E, which is a pin to pin
replacement, but the RF parameters remain unchanged, and other RF circuits and RF chips
remain unchanged.
3. In order to optimize the PCB size, the circuit diagram and the PCB layout have been adjusted to
deleted some unused H bridge drive ICs, peripheral circuits and unused interfaces.
4. L2C enables SRD (5170-5250) MHz through software, but this frequency band is not enabled on
L2A.
5. Enabled Galileo receiver function through software
