Building the TNC-Pi

Parts for the TNC-Pi as they arrive in packages
The unpopulated TNC-Pi circuit board
Collecting together the axial lead parts for the first steps
0.1u monolithic capacitors installed
100K resistors installed
1K resistors installed
10K resistors installed
1% resistors installed
Remaining parts gathered for next steps
Crystals installed
Closer look at crystals - note markings
IC sockets installed - don't put ICs in until later
Install remaining capacitors
Installed transistors, voltage regulator, LEDs
Be sure the flat side of the transistor is toward the inside of the board
And the flat side of the voltage regulator is toward the outside of the board
TNC-Pi mated to Raspberry Pi
Final screw holding TNC-Pi to Raspberry Pi
