The K3 testboard for 16F873
The K3 testboard is used for building
various experimental circuits. It contains a 28 pin socket for the 16F873.
K3 is a stripboard with predrilled holes. K3 measures 10 cm x 8 cm.
The main components are: A 7805 bolted to a small heatsink, a blue
reset button, a red LED, a serial I2C EEPROM (24LC256), four
DIL switches, the 16F873 with 4 MHz crystal oscillator, a real time clock
(DS1302) with lithium battery backup and a MAX232 for serial communication.
I'm using an external power supply which is able to provide 12V DC at 300
