PecanPico4 is in the works

I just sent out the Gerber files for a new version of PecanPico to the PCB house. It has the following improvements:
– Optimized resistor network for a finer tuning of the VCXO
– Pin GPIO0 is now directly connected to the ATmega (PD4)
– Added piezo speaker / beeper
– Added RGB sensor (TCS3471)
– Added EEPROM
– Changed pressure sensor from BMP085 (depreciated) to BMP180
The PCB has still the exact same size (about 2 x 1 inch)
