Digital Readout for Kenwood TS-520S
This PCB was designed by Steve KV6O
http://www.kv6o.com/wordpress/projects/kenwood-dg5-emulator/
Parts Info:
http://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=03394fdd5d – Mouser parts, includes most of the components.
http://sfe.io/w97558 – SparkFun parts, includes RCA jacks, LCD display, 4″ jumpers for the display, etc.
The LCD is the most expensive part in the build (besides an Arduino), if you have one already the parts are about $20. Less if you have a well stocked parts bin. Arduino’s can be had for less than $10 on eBay, and the LCD display (a 16×2, HD44780 based display – very common) can be had for a few bucks if you look around and can wait on shipping.

Simple DC brushed motor driver using TI’s DRV8837 1.8 A PWM-controlled H-Bridges. Board is designed to be mounted onto a Teensy 3.X although it can also be used on a breadboard. The H-bridges allow the motors to be driven both forward and reverse, with braking and coasting options as well. SLEEP pin HIGH enables the motors. Added zero resistor jumper to connect VM and VCC and added GND vias.
