The DRO-350 is a three-axis digital read-out (DRO) for import Chinese scales. It is designed to be as capable as commercial DROs but at a lower cost for the metal-working hobbyist or small machine shop. The DRO-350 is a do-it-yourself (DIY) project, not a complete, commercially manufactured product. You will receive everything necessary to construct a fully functional DRO head and need only to select the scales to fit your machine.
Concerned that the DRO-350 is "obselete"? READ THIS.
Release 5 (beta 1) firmware for the DRO-350 is now available. Read about it here. Make your selection below under "Product Options".
The DRO-350 Complete Kit includes everything needed to build a 3 axis DRO-350:
- Product # DRO350PBK Processor Board Kit
- Product # DRO350CSK Case Kit
- Product # DRO350ICA Internal Cable Kit
- Product # DRO350FP Faceplate (Please refer to the Faceplate description for important information.)
- PIC MPU Socketed
- Does not included are external cables or power supply. (Cable components and power supply are found elsewhere in our catalog.)
This kit requires a moderate level of skill in soldering. The only tools needed for assembly are a phillips and common screwdriver, wire cutters, solder and a soldering iron (25w or temperature controlled with a fine tip is recommended).
Caution - This kit contains static sensitive items. Follow accepted static prevention practices when handling.

HINT: Whether you use rosin core solder or water-soluble flux core solder, your board should be cleaned when completed to remove any remnents of flux which remain on the board, you should clean the board after all parts on the components side of the board are installed. This is before you install the 7 segment LEDs, the indication LEDs or the switches.
There are two reasons for this:
- Portions of the solder side on the board will be covered by the LEDs and switches after they are installed.
- By cleaning the board without these items installed, you eliminate any chance of damaging them during the cleaning process.
After the LEDs and switches are installed, you can carefully clean the flux from the solder joints for these components on the component side of the board.
Check with your solder manufacturer's web site for information on what cleaners should be used with your solder.
