Would be interesting if you could interface the Raspberry Pi to the baofeng so you could control its VFO and change frequency as well. Like, imagine having a Raspberry Pi with a GPS that would know your current location and know what repeaters you could hit.
Notes: August 1, 2016: The schematic showing the serial interface has been updated. Its Revision has been changed from Rev. X to Rev. X2. The circuitry was modified to allow me to use a USB-Serial Adapter Cable manufactured by FTDIChip in lieu of the Elecraft KXUSB cable I had been using.
New shield Real Time Clock is applicable to an Arduino Uno R3 card to a Raspberry Pi 2.0 / 3.0 / B +. Particularly suitable in all those applications that require the time information, which is obtained locally by circuits called RTC (Real Time Clock) or RTCC (Real Time Clock Calendar); among them the radio alarms, the registration systems for personnel access, those of timed on / off etc.
It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
The addition of a GPS receiver to a Raspberry Pi gives it both positioning and high accuracy time capabilities. Perfect for when you need to ascertain the location of equipment which is on the move and with systems that require accurate time.
