Development kit version with laser trimmed VCO calibrated silicon
Question: How to determine the version of the development kit which has a laser trimmed VCO calibrated silicon?
Response: A radio module that has a black PCB then the silicon has the VCO calibration laser trimmed data from the factory. The final release of the development kit (part# CY3632) ships with black PCB radio modules.
General note: The final release of the development kit with firmware v1.3 or greater does not write to the REG_VCO_CAL register, as required by the non-laser trimmed ES-10 silicon. Until you receive the black PCB radio modules your firmware needs to write value 0xB0 to the REG_VCO_CAL register as done in the ES-10 firmware v1.2.
